Study Guide for Cardiac Assessment
 Anatomy and Physiology
 Base
 Apex
 Pericardium
 Parietal
 Visceral
 Precordium, Apex, and Base
 Anatomy and Physiology
 Chambers of the heart
 Right and left atria
 Right and left ventricles
 Heart Valves
 Semilunar valves
 Pulmonic
 Aortic
 Atrioventricular valves (A-V)
 Tricuspid
 Mitral
 Conduction
 Heart has unique ability: automaticity
 SA node has intrinsic rhythm, it is called the pacemaker
 Current flows in orderly sequence, SA to AV to bundle of His, right and left bundle branches, and then
through ventricles
 Electrical impulse stimulates heart to do its work, which is to contract
 Small amount of electricity spreads to body surface, and can be measured and recorded on
electrocardiograph (ECG)
 ECG
 ECG waves arbitrarily labeled PQRST, which stand for
 P wave: depolarization of atria
 P-R interval: from beginning of P wave to beginning of
 QRS complex (time necessary for atrial depolarization plus time for impulse to travel through AV
node to ventricles)
 QRS complex: depolarization of ventricles
 T wave: repolarization of ventricles
 Electrical events slightly precede mechanical events in heart
 Conditions Related to Coronary Circulation
 Ischemia
 Infarction
 Angina
 Cardiac Output

 Landmarks – APE To Man
 A=Aortic 2nd ICS RSB
 P=Pulmonic 2nd ICS LSB
 E= Erb’s point 3rd ICS LSB
 T= Tricuspid 4th ICS LSB
 M= Mitral 5th ICS MCL
 Auscultation
 Warm stethoscope
 Listen to all ______cardiac landmarks
 Listen for at least a few cardiac cycles in each area
 Listen first for S1 and S2, then for possible S3 and S4.
Finally listen for murmurs, clicks and friction rubs
 Normal Systolic Sound: S1
 S1 – blood heaves against the closed mitral and tricuspid
valves in the heart
 High pitched – heard with diaphragm
 Heard best at Apex –____________area
 LUB – dub
 Normal Diastolic Sound: S2
 Represents closure of aortic and pulmonic valves
 Heard best at Base –____________area
 lub – DUB
 Auscultation: Normal Findings
 Aortic: S2 is louder than S1
Pulmonic: S2 is louder than S1

Midprecordial (______________) both aortic and pulmonic murmurs by be heard

 Tricuspid: S1 is louder than S2
 Mitral: S1 is louder than S2
 Mitral and tricuspid: S3 (gallop) may be heard in children, young adults, and pregnant women. S4 may
indicate cardiac decompensation
 Evaluating Cardiac Sounds
 Rate
 Bradycardia
 Tachycardia
 Rhythm
 Murmurs, Gallops Clicks or Rubs
 Abnormal Finding - Murmur
 Blowing, whooshing, or rasping sounds
 The result of vibrations caused by abnormal blood flow patterns
 valve does not close tightly (such as with mitral regurgitation)
 an irregularity in the shape of a heart chamber or one of the great vessels (such as an aortic
aneurysm)
 Blood is flowing through a narrowed opening or a stiff valve (such as with aortic stenosis).

 Does not necessarily indicate a disease or disorder, and all heart disorders do not cause murmurs.
 If difficult to hear
 Place in lateral recumbent position – low pitched, mitral – use bell
 Lean patient forward – high pitched, aortic or pulmonic – use diaphragm
 Murmurs – Seven Descriptive Characteristics
 Location (where it is loudest)
 Radiation (from valves to adjacent anatomic areas)
 Timing (systolic, diastolic)
 Loudness/Intensity
 Quality (description)
 ________________ (high, low)
 Pattern (crescendo, decrescendo)
 Grading Intensity of Murmurs
 The intensity of murmurs range from grade 1/6 to 6/6. A
murmur is said to be at least Grade 4/6 if associated with a ____________
 Abnormal Finding
 Click
 _________________Heart valves – mitral and aortic most common
 Click noted especially with mechanical valves, human tissue valves produce sounds similar to
human valves – but may produce a murmur
 Pericardial friction rub
 Caused by rubbing together of the inflamed visceral and parietal layers of the pericardium
 Noted in ____________________
 Characterize based on location, radiation, timing, quality and pitch
 Does not change with respiration
 Bruits
 For persons middle-aged or older, or who show symptoms or signs of cardiovascular disease, auscultate
each carotid artery for presence of a bruit
 This is a blowing, swishing sound indicating blood flow turbulence; normally none is present
 Lightly apply bell of stethoscope over carotid artery
 Avoid compressing artery
 artificial bruit and could compromise circulation
 Ask person to hold an exhaled breath so that tracheal breath sounds do not mask
 Sometimes you can hear normal heart sounds transmitted to neck; do not confuse these with a bruit
 Assessment of Arterial Pulses
 Evaluate carotid, brachial, radial, femoral, popliteal, posterior tibial, dorsalis pedis
 Patient position
 Characteristics: rate, rhythm, amplitude, symmetry
 Other CV assessments
 Carotid and Popliteal pulses
 Dorsalis Pedis and Post-Tibial pulses
 Capillary Refill
 Peripheral Edema

 CMS Check
 C (_______________)
 M (Motor function) – neuro function
 S (Sensation)- neuro function
 Homan’s Sign
 Sharply dorsiflex foot toward tibia
 Should be no pain in calf muscle
 Tenderness could indicate DVT
 If DVT suspected, measure calf circumference with nonstretchable tape measure
 Notify _______________________
 Not routine assessment; used in OB
 Cardiovascular assistive devices
 Artificial pacemakers, ICD
 Hemodynamic monitoring
 Antiembolic stockings
 Chest tubes
 EKG monitoring
 IV Catheters
 Infants
 Heart rate best auscultated because radial pulses are hard to count accurately; use small (pediatric size)
diaphragm and bell
 170 bpm or more with crying or being active to 70 to 90 bpm with sleeping
 Expect heart sounds to be louder in infants than in adults because of infant’s thinner chest wall.
 Murmurs are relatively common in first 2 to 3 days because of fetal shunt closure
 Children
 Physiologic _______________ is common in children
 Heart murmurs that are innocent (or functional) in origin are very common through childhood
 Most innocent murmurs have these characteristics
 Soft, relatively short systolic ejection murmur
 Medium pitch; vibratory
 Best heard at left lower sternal or midsternal border, with no radiation to apex, base, or back
 Pregnancy
 Enlarging uterus elevates diaphragm and displaces heart up and to left and rotates it on its long axis
 Heart sounds
 Exaggerated splitting of S1 and increased loudness of S1
 A loud, easily heard ____________________
 Heart murmurs
 Systolic murmur in 90% which disappears soon after delivery
 Aging Adults
 Chest often increases in anteroposterior diameter with aging
 More difficult to palpate apical impulse
7
Page 8 of 8
 S4 often occurs in older people with no known cardiac disease
 Systolic murmurs common, occurring in over 50% of aging people
 Peripheral blood vessels grow more rigid with age, resulting in a condition called arteriosclerosis
