An Electrocardiogram (ECG) is a simple, quick, and non-invasive test that records the electrical activity of the heart. It helps detect abnormalities in heart rhythm, heart rate, and electrical conduction. ECG is one of the most commonly performed cardiac tests and provides valuable information about heart health within minutes.
An ECG can reveal conditions such as arrhythmias, heart attacks (past or ongoing), heart enlargement, electrolyte imbalances, and effects of certain medications. It is often used as a first-line diagnostic tool in patients presenting with chest pain, palpitations, breathlessness, or dizziness.
