ABSTRACT
HAND-HELD PACER MONITOR
by
Shin-woong Rhee
- Master of Science in Engineering
January, 1979
Within the past few years, the clinician has witnessed the mpid
evolution in the field of electrical __monitoring of the heart.
Long term monitoring with a portable EKG(14) tape recorder has become
increasingly popular for outpatient use, but measuring the vital
pa.mmeters of pacemaker performance on the EKG strip is not good
enough(S). The reasons are the pulse width of implanted pacemaker can
hardly be measured and pulse rate of implanted pacemaker can-not be
measured directly from EKG strip. Therefore, we design here a new
hand-held pacer monitor featuring a digital display for immediate
readout in milliseconds (pulse width and pulse period) or pulses per
minute (pulse rate}. The hand-held pacer monitor is ideal for easy use
and portability in home, doctor's office and hospital.
The monitor incorporates an exclusive microprogram which offers
the practicing physician an accumte method for measuring the vital
vii
parameters of pacemaker performance. This monitor ban be used without
lead wires, cables or limb connections, also, no electrode gels or
pastes are required.

INTRODUCTION
Cardiac pacing with an implanted unit has a short history of about
20 years(?). Pacemaker technology has seen many improvements since
. 1960. For example, we have progressed from a two-tra.ns.istor discrete
component system to hybrid-integrated systems employing hundreds of
semi-conductor junctions(6). During this time, it bas become clear
that patients with implanted cardiac pacemaker have to be controlled
regularly. Furthermore, the increasing number of patients has made
.
it more and more difficult to check adequate performance of implanted
.
.
cardiac pacemaker, because the conventional methods are time consuming
and demand costly equipment(4).
Most of the pacemaker manufacturers have made the rate of the
pacemaker dependent upon the output of the batteries. In this way,
the doctor in the clinical field has obtained a simple method of
detecting impending battery deterioration which occurs in an orderly
manner with rate moving up or moving down depending upon the circuit.
This rate change helps determine the most appropriate time for
pacemaker replacement; both wastful premature replacements and .
emergency replacements of the pulse generators can thus be prevented.
However, from a clinical point of view, it is also desirable to be
able to control the electrode system, (especially as regards
1
2
fractures, isolation defects and displacement), and the physiological
threshold for pacing in a simple way(4).
Presently, implantable cardiac pacemakers are more reliable because
of the improving reliability of the pacemaker power source.
In 1970 a lithium-iodine battery(21) was introduced which uses a
lithium anode, an iodine cathode and a crystalline, solid-state
electrolyte of lithium-iodine with high capacity per unit weight and
volume. Since 1970, over 100,000 cardiac pacemakers powered by lithiUlll
-iodine battery have been implanted and manufactured in 9 countries
by 20 makers(20). Before the introduction of the lithium battery,
most implanted cardiac pacemaker had powered by zinc-mercury.batteries.
In practice, this battery usually fails before one-half its rated
charge capacity is delivered. In earlier years, average survival times
of 24 months or less were reported.l;ly Furman(11). But todays average
survival time is about 10 years.
Following implantation of a permanent pacemaker, the patient
should be examined periodically to determine i f the pacemaker is
operating properly and i f the patient is being paced adequately.
Surveillance is vital in determining impending battery depletion
and other events such as component or electrode failure.
Therefore, the goal of this paper is the design of a hand-held
pacer monitor which is easy to use, gives accurate measurement, and is
portable.·

TYPE OF PACEMAKER AND
ITS FUNCTIONAL CHECK
Almost two decades
ago~
Zoll developed lifesaving external pacing
for otherwise fatal heart block(2). In 1960 Chardack and Greatbatch
implemented the concept of an implantable, long-life, cardiac
stimulation system. The Chardack-Greatbatch pacer was an asynchronous
oscillator which functioned independently of normal cardiac activity.
In 1965 Berkovits and Harkin developed an non-competing demand pacer
system which withheld its stimulus in the presence of normal cardiac
activity. In 1970 Berkovits introduced
.,, an additional adaptive pacer,
the Bifocal pacer which offers improved cardiac output for certain
patients, by sequentially stimulating the atrium and ventricle, and
the modern age of implantable pacer had arrived(13).
There are four basic types pacing modes(1,8,13,14); fixed rate,
P-wave synchronous, R-wa.ve demand and bifocal. The pacemaker family
is shown in Figure 2. 1.
2.1 THE FIXED RATE PACEMAKER: The fixed rate (asynchronous) pulse
generator emit electronic impulses at fixed intervals and at fixed
pulse strength without regard to the :patients intrinsic rhythm.
The electronic pulse consists of a square wave or capacitor discharge
from
0.5 to 2.0 milliseconds duration. Pulses are usually emitted at
a rate of 70 per minute.

When the heart is in complete block (no natural depolarization occurs)
the_pacemaker initiates all ventricular contractions, and regular,
forceful pUlllping results. But i f the heart comes out of block, arid
resumes spontaneous conduction, then we have competing rhythms. It
often happens that the ventricles are affected by both the natural
and the pacemaker impulse. In each such case, the myocardial
contractions are badly coordinated, this causes ventricular
fibrillation by stimulation in the vulnerable zone of the "T" wave,
and pumping efficiency is thus impaired. This can be a serious health
factor in occasional patients. The occurrence of competing rhythms is
the major drawback of asynchronous pacemaker. The EKG strip is shown
in Figure 2.2. This pacemaker can be checked easily at any condition
with hand-held pacer monitor since the pacemaker generates the pulse.
2.2 THE P-WAVE SYNCHRONOUS PACEMAKER: The
P-~mve
synchronous
pacemaker has more complex circuitry than simple fixed rate pulse
generator. This pacer senses the atrial contraction (the P-wave),
waits about 0.1 second (i.e., generates the proper A-V delay), and
then releases·<a pacing pulse to the ventricles. So when the body
requires more
oxyg~l'l,
and atrial rate increase, the pacemaker follows
along, increasing ventricular rate accordingly. Therefore proper A-V
synchrony is maintained. If there is no atrial contraction (P-wave)
pacer begins to release its full time interval. It works on demand
mode. The Figure
2.3 shows EKG strip and the interaction between the
pacemaker and the heart. This pacemaker can be checked easily by the
hand-held pacer monitor because pacer is always pacing.
2. 3 THE R-WAVE DEMAND PACEMAKER: The R-wave demand pacemaker has

two types. The first is the R-wave synchronized pacemaker and the
second is the R-wave inhibited pacemaker.
2. 3.1 THE R-WAVE SYNCHRONIZED PACEMAKER: The R-wave synchronized
pacemaker, which operates on essentially the same principle as a Pwave synchronous pacemaker. As long as the heart is in block, the
pacemaker drives the heart at a pre-set rate (usually 70 beat), in the
same fashion as with the R-wave inhibited pacemaker. But when any
natural ventricular contraction occurs, the pacemaker senses each
ventricular depolarization, and releases its output within few milliseconds (i.e., essentially simultaneously). This pulse reaches the
myocardium after depolarization has occured which is refractory. So
the pacemaker pulse is ineffectual. The Figure 2.4 shows the EKG strip
and the interaction between the pacemaker and the heart. This kind
pacemaker can be checked easily
beca~se
pacemaker is always pacing.
2. 3. 2 THE R-WAVE INHIBITED PACEMAKERs The R-wave inhibited
pacemaker has become the most widely-used type of pacemaker in the
world. When the heart is in block, the demand pacemaker takes over,
feeding a pacing pulse to the heart. In this mode, the pacemaker
operates at a fixed rate. It cannot vary in rate to meet· changing
bodily oxygen requirements. If the heart comes out of block and begins
to pace itself, the pacemaker senses this - it "watchs for" any R-wave
picked up by the pacing electrode. In this event, the pulse generator
is inhibited, and no pacing pulses
a~
released. The EKG strip is
shown in Figure 2. 5.
2.4 THE BIFOCAL PACEMAKER(1,2,13,14): The bifocal pacemaker drives
both the atrial and the ventricles, and is an attempt to provide

proper A-V synchrony when pacing, so as to achieve• maximum hemodynamic
benefit (pumping efficiency), without the trauma involved in
implanting an atrial synchronous Jla.cema.ker. This pacemaker has two
electrodes that is one in the atrium, and the other one in the
ventricle. It has to be emphasized that the ventricular electrode has
a double function. It senses the electrical (ventricular) signal and
also stimulates the ventricles when required. The atrial electrode
only stimulates the atria, but has no sensing function. Therefore,
the signal detected by the ventricular electrode is responsible for
both atrial and ventricular pacing. When the pacellaker is pacing, it
releases two pulses for every beat, one is the atrial pulse, the
other one is a ventricular pulse which comes about 1/10 second after
the atrial pulse. This cycle preserves proper A-V synchrony. The EKG
strip is shown in Figure 2. 6.
'""
Most demand pacemaker has a magnetic reed switch that enables
physician to convert the pacemaker to fixed rate mode (free-running).
This enables hill to determine. if the pacemaker will stimulate properly
when it is in the nonpacing mode. A magnetic reed switch activated by
an exte:mal magnet is incorporated in the :pacemaker. This switch
transforms the R-wave inhibited pacemaker or the ventricular part of
the bifocal pacemaker from a demand to a continuous mode of operation,
and permits testing of these pacemakers with the hand-held pacer
monitor. The EKG strip with magnet is shown in Figure 2.7.

SYSTEM DESCRIPTION
The easiest method(10) of determining heart rate is to count the
. patient's peripheral pulse for one minute. Many patients do this
·themselves one or twice a day. Obviously, the possibility of premature
beats and the possible return of patient's own rhythm limits this
method. Under these same circumstances, activation of the magnetic
reed switch can also produce competition. The most readily available
tool for detecting pacemaker pulses
is~.~
portable radio. The radio
must be tuned between stations so the clicks it produces in response
to pacemaker stimui are audible. The built-in antenna can be directed
· to pick up the electromagnetic field of the current pulse flowing
through the chest between the stimulating electrodes. This field is
stronger with unipolar pacemakers than with bipolar ones; in bipolar
pacemakers the current is concentrated between the adjacent electrodes,
. therefore its effect is weak at the chest wall. Figure 3-1 shows
waveform from the implanted unipolar and bipolar pacemaker.
The simplified block diagram is shown in Figure 3-2. If the pickup device differentiates the picked up signal from the pacemaker, the
performance (pulse period and pulse width) of the pacemaker might be
checked easily at any condition. The pick-up plate as a pick-up device
with one resistor is a differentiator. Therefore, the input signal is
differentiated by the pick-up plate and next the differentiated signal

is amplified and filtered so that the leading and trailing edges may
be detected. The double-ended limit detector (window comparator) as
a detector is useful for the pulse width measurement of the pacemaker.
The digital display with BCD positive logic input including onboard decorder/driver and memory is s~ll size and easy to be used
with PROM. When a spike is detected, sense light flashes and the
measurement is displayed.
The hand-held pacer monitor is realized by the block diagram
shown in Figure J-J. The electromagnetic signal of the current pulse
flowing through the chest between.the stimulating electrodes can be
picked up by a pick-up plate. The resultant signal is then amplified
by a pre-amplifier. The gain of the pre-amplifier should be high
enough to trigger next stage because the signal which is picked up by
the pick-up plate is very small. Then-the noisy amplified signal from
the pre-amplifier is filtered. The signal out of the filter has a
positive and negative pair spike train; the distance between positive
and negative spike represents pulse width of implanted pacemaker. If
the pick-up plate is located far from the electromagnetic field
source, positive spikes might not be seen at the filter. This
condition makes it unable to detect pulse width of the implanted
pacemaker. The double-ended limit detector transforms the positive
and negative spike pairs to negative double pulses; these negative
double pulses are the mputs
to--a --ITlonostable
oscillator (one . shot)
whose output is used as a reset pulse for reseting all counter.
The crystal controlled oscillator generates a 100KHz square wave
which is used for counting. For the display of pulse width of the

implanted pacemaker, this 100KHz square wave feeds the BCD up counter
which is connected to numeric display (including decorder/driver with
5 bit memory
8-4-2~1
BCD positive logic input) through the switch SW1.
The counter is reset and starts counting from the first negative
pulse and stops at the second negative pulse of the double pulses
from the double-ended limit detector (window comparator), the number
of the square wave pulses during that time will be the pulse width
of the pacemaker in milliseconds. The 100KHz square wave is divided
by the factor 100 for the display of pulse period and pulses per
minute. For the display of pulses per minute (PPM) of the pacemaker,
the square wave pulses between the first negative pulse and following
first negative pulse are sent to 12 bit binary counter which drives
the programmable read only memory (PROM) which is 1024 x 8 bit
capacity. The PROM was programmed a~ .§0,000/number of counted square
wave pulses during the pulse period. For a 4 digits display, two
PROMs were used, the output (4 wires per each digit) drives the
display which shows pulses per minute (PPM).
The pick-up indicator was used for indicating that the pick-up
plate picked up a pulse from the pacemaker. Whenever a pulse is
picked up the LED indicator flashes, thus, i f the LED is not flashing
the number which is showing on the display is meaningless.

CIRCUIT DESIGN
This chapter provides descriptions of the circuits used to
implement each of the functional blocks described in chapter 3. For
the circuit design readily available components and intergrated
circuits were used.
PICK-UP PLATE
A piece of commercial PC card (1/16" x 1" x 2") with both side
coated by solder was used as a pick-up plate. The capacitance of this
pick-up plate is normally 35 pf, and the PC plate makes a
differentiator with R1(100
Kn).

It can be seen from the Fourier analysis that the parameters to
, be varied are the amplitude and frequency whose spectrum is 6.25 KHz,
18.?5 KHz, 31,25 KHz and etc. The frequency of interest in this design
is 6.25 KHz.
A active wide-band band pass filter is obtained by cascading a
active high pass filter whose cutoff frequency is 1 KHz with a active .
low pass filter whose cutoff frequency is 10 KHz.
For the maximally flat frequency response, damping factor should
be 0.?07 which is a Butterworth second order filter. The second order

ONE SHOT MULTIVIBRATOR
A one shot (monostable multivibrator) is a half analog/half digital
circuit that produces a pulse on its output in response to a trigger
signal at its input. And the circuit is sho;m in Figure 4-12.
The MC14528 which was used in this design is a C-MOS dual,
retriggerable and resettable monostable multivibrator. It may be
triggered from leading or trailing edge of an input pulse, and will
produce an accurate output pulse over a wide range of widths, the
duration and accuracy of which determined by the external timing
components, Cx and Rx. Once the presence of the signal from the
window comparator is detected, the falling edge will trigger the
multivibrator which is one half of MC1452B (U1-1). The output pulse
width is determined by Cx and Rx.
For Cx <. 0, 01 )lf, use graph for y,,= 5 Volt level.
For Cx)0,01

use :formula; PWo

connected to falling edge trigger input of U2-2. 'The noninverting
output of U2-2 whose pulse width is
50 ps from the graph was used for
reset pulse of all counters. The Figure 4-13 describes timing diagram.
PACING INDICATOR
The technique chosen for the pacing indicator is basic comparator
circuit which is diagrammed in Figure 4-14.
Eyef
is a positive voltage
(1.8V) applied to the inverting input of comparator which is the one
out of the quad comparator (A2-3) in the MM74C909 package. Ein is the
signal from the inverting output of U1-2, applied to the noninverting
input. When Ein is lower than reference voltage
En!f
(1.8V), the output
of A2-3 will be zero. If the output of A2-3 is zero, the LED will be
flashing because LED is under forward bias. As soon as Ein rises
higher than
LED
E~f•
the comparator output flips to the +5
will not be flashing any more. ,,,

OSCILLATOR
A crystal-controlled oscillator that can be used to generate the
clock in slower digital system is shown in Figure 4-15. The freerunning crystal-controlled oscillator is the versatility of the
comparator. The inputs are biased within the common mode range by R1
and R2. The value of R1 and R2 are equal so that the comparator will
switch symmetrically. DC stability at the inverting input, which
insures starting, is provided by negative feedback through R3. The
negative feedback is reduced at high frequencies by C1. At some
frequency the positive feedback through a quartz crystal will be
greater than the negative feedback; and the circuit will oscillate
when transmission through the crystal is at a maximum, so the crystal
operates in its shunt-resonant mode. The high input impedance of the
· comparator minimizes loading of the crystal and contribute to
frequency stability. For 100
KHz
square-wave output all components
value are shown in Figure 4-15. !n this design MM74C909 which is C-MOS
quad comparator and SX-1V-100 KHz which is package in T0•5 can were

UP COUNTER
Figure 4-16 shows CD4518 which is C-MOS dual BCD up counter
cascaded for four digits display with positive-edge triggering
configuration, The counter is cascaded in the ripple mode by
connecting Q" to the enable input of the subsequent counter while the
clock input of the latter is held low, The flip-flop QA has a weight
of 2" (or 1) when its output is logic "1". Flip-flop Q5 has a weight of
2' (or 2),
Qc
3
has a weight of 2 ;l. (or 4) and Q D has a weight of 2 (or 8).
The number stored in the counter at any specific time can be
determined by summ.ing decimal weights of flip-flop in the logic "1"
state. A counter that counts in a standard binary manner and recycle
per every 10 clock pulses is called an 8-4-2-1 BCD counter,
Every output of this counter is connected directly to display
(HP5082-7300) which includes decorder/driver with 5 bit memory, The
counter should be reset at the begining of every pulse and just before
reseting the counter all data should be latched up for pulse period
and pulse per minute measurement, And for the pulse width measurement
the counter should be reset at the begining of pulse and all data
should be latched up at the end of pulse. Figure 4-13 describes all
timing dia.gra.m.
DIVIDER
MC14518 (C-MOS dual BCD up counter) is used as a divider in this
design, In the dia~m 4-17 enable- input- (pin 2 & pin 10) is always
+5 V and reset input (pin 7
& pin
15) is always grounded. The highest
output (pin 6) of first half of counter is connected directly to
'
clock input (pin 9) of second half of counter, Any time clock input

received the 100 KHz pulse, the highest output of each counter comes
out divided by 10 output. Therefore over-all factor of division is
100. If clock input (pin 1) received 100 KHz clock, then output
(pin 14) comes out 1 KHz. 100 KHz pulse is used for pulse width
counting and 1 KHz pulse is used for pulse period/pulses per minute
counting.
12 BIT BINARY COUNTER
MC14040 which is C-MOS 12 bit binary counter was used in this
. design (Fig. 4-18)~ This device has 12 binar,y weighted outputs. But
only 10 outputs,
Q,
through Q,0 out of 12 outputs, were used because
the maximum capacity of prograJIIIla.ble read only memory (PROM) is 1024
words x 8 bits
(Z 0
= 1024). Every output of this counter is connected
directly to the address input of PRml. Every time a clock input is
received the corresponding output will be logic "1 11 state. This
,,,~K

•
•
counter should be reset at the same time of the BCD up counter.
PROM
825180 which is 8192 bit bipolar PROM (1024 x 8 bit) was used in
this design. 1024 words are used for the input which is connected to
12 bit binary counter and 8 bits for the output which directly drives
. the display. Any time the input address lines receive a pulse the
. output will be pulses per minute which is programmed as 60,000/pulse
. period in milliseconds
= PPM. The range of microprogram
is between
. 500 ms (120 PPM) and 1500 :ms (40 PPM). Most pacemaker manufacttll.'ers
are making pacemakers in this range (72 PPM pacemaker is standa:rd).
From this range, between words 0 and 499 are open and from wo:rds 1024
· to 1500 are over capacity. But this open 'range can take care of this

DISPLAY
Numeric HP 5082-7300 with right hand decimal point which includes
decorder/driver with 5 bit memory was used. This display has 8-4-2-1
BCD positive logic input and 4 x 7 dot matrix
array~
Positive logic
input is connected to the PROM. Figure 4-21 shows all connections.
For the pulse width display the decimal point will be the 2nd
digit and for the pulses per minute display the decimal point on the
Jm digit should be on. For the pulse period display all decimal
points should be grounded. The number on the display is the pulse
period or pulse width in milliseconds and pulses per minute in PPM.
If pacing indicator LED is not flashing, the number on the display
is meaningless.
