Abstract:
In a study of 877 patients presenting for anaesthesia with an ECG, 45 per cent of the ECGs were found to be abnormal. The incidence of abnormal ECGs was found to be highest in the over-40 age group, and also in those patients of ASA Grades II, III, IV and V, and this investigation is therefore recommended in these patients.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
