Electrocardiogram (ECG)
What is an ECG?
An electrocardiogram records the electrical activity of the heart using electrodes placed on pre specified locations on the chest wall and all the 4 limbs.
How long is the test?
The test takes anywhere from 5 -7 minutes.
How should I prepare for the test?
Avoid any cream or lotions on the chest prior to the EKG as it might interfere with the electrodes making contact with your skin.
What is an ECG used for?
EKG is most useful in detecting electrical conduction abnormalities, arrhythmia (abnormal rhythm), hypertrophy (thickening) of heart muscle, congenital heart diseases, as well as presence of active coronary ischemia with lack of blood supply to the heart or history of myocardial infarction with permanent heart muscle damage. This test is often repeated over time to follow the progress of the condition and treatment.
