Diagram of the Heart
Teacher’s note to be removed before showing chn: Chn may be confused by the left and
right being apparently the wrong way round – tell them that the picture is of a heart as
though it was in somebody facing them and the teacher should hold the diagram above
their own heart so that children can see that the right chambers on the diagram are on
the teacher’s right side, holding their right hand up.

Electrocardiogram
An electrocardiogram or 'ECG' records the electrical activity of the heart. The heart
produces tiny electrical impulses which spread through the heart muscle to make the
heart muscles contract. These impulses can be detected by the ECG machine. You may
have an ECG to help find the cause of symptoms such as palpitations or chest pain.
Sometimes it is done as part of routine tests, for example, before you have an
operation.
You often see ECG on a heart monitor being used during TV hospital soap operas.
The ECG test is painless and harmless. (The ECG machine records electrical impulses
coming from your body - it does not put any electricity into your body.)
How is it done?
Small metal electrodes are stuck onto your arms, legs and chest. Wires from the
electrodes are connected to the ECG machine. The machine detects and amplifies the
electrical impulses that occur each heartbeat and records them onto a paper or
computer. A few heartbeats are recorded from different sets of electrodes. The test
takes about five minutes to do.
What does an ECG show?
The electrodes on the different parts of the body detect electrical impulses coming from
different directions within the heart. There are normal patterns for each electrode.
Various heart disorders produce abnormal patterns. The heart disorders that can be
detected include:



Abnormal heart rhythms. If the heart rate is very fast, very slow, or irregular.
There are various types of irregular heart rhythm with characteristic ECG patterns.
A heart attack, and if it was recent or some time ago. A heart attack causes
damage to heart muscle, and heals with scar tissue. These can be detected by
abnormal ECG patterns.
An enlarged heart. Basically this causes bigger impulses than normal.
