ECG (Heart Tracing)

An ECG is a quick, painless recording of your heart’s electrical activity, offering an immediate window into your heart’s rhythm, rate and overall function.

About the ECG (Heart Tracing)

An electrocardiogram (ECG) records the electrical signals that make your heart beat, using small sensors placed on the skin. It can reveal irregular heart rhythms, signs of strain, and other cardiac changes, and is a valuable part of assessing palpitations, breathlessness or chest discomfort, as well as routine heart health checks and pre-procedure assessments.

Preparation and turnaround

The ECG is non-invasive and painless, requiring no fasting; you simply rest while sensors are briefly placed on your chest, arms and legs, and the recording takes only a few minutes. Results are available promptly and are best reviewed by a doctor. Important: sudden or severe chest pain is a medical emergency — seek immediate care rather than booking a routine test.
