Importance of the ECG test and what can be detected in the test

• The ECG is a graphic record of the changes in electrical activity which occur within the heart muscle during each heartbeat. It is registered on a continuous strip of graph paper.

• The electrocardiogram will normally pick up abnormalities in rhythm or heart size, and also any damage to the heart muscle (myocardium).
• The test can be performed while the applicant is at rest or after he has carried out a carefully measured exercise i.e. pre and post exercises.
• Always request for the Doctor’s report.

What is detected by ECG?

1. Arrhythmias – Irregularity in the rhythm of the heartbeat (Heart rate <60/min is bradycardia; >100/min is tachycardia)
2. Myocardial infarction – Death of part of the heart muscle
3. Peri-carditis – inflammation of the sac enclosing the heart
4. Ventricular hypertrophy
5. Ischemic Heart Disease
6. Heart (AtrioVentricular) Block (1st, 2nd and 3rd degrees) & Bundle Branch Block – Heart failure and sudden death.
