What is an Electrocardiogram (ECG)?
This is a recording of the electrical activity of the heart.
What happens in an ECG test?
Multiple electrodes are placed over the chest wall and limbs in standard positions. The small electrical signal from the heart is then recorded. The procedure is totally harmless, painless and takes about 5 to 10 minutes to perform, although the chest electrodes may sometimes impinge some red marks on the chest wall, which will fade away in few days time.
Do I need to prepare for this test?
There is no preparation required for this test.
Why do I need an ECG?
The ECG can provide your Doctor with invaluable information on the electrical rhythm of the heart, its electrical conduction, muscle mass, presence of arrhythmia, ischaemia or infarction and even electrical disturbance and drug effects. It is a routine cardiac investigation procedure.
