ECG (Electrocardiogram)
An Electrocardiogram (ECG/EKG) records the electrical activity of the heart. It detects irregular heartbeats (arrhythmias), heart attacks, enlarged heart chambers, and other cardiac conditions. It is a quick, painless, non-invasive test done by placing electrodes on the chest, arms, and legs.

Measures
Heart rate, heart rhythm, electrical axis, P-wave (atrial depolarization), PR interval, QRS complex (ventricular depolarization), ST segment, T-wave (ventricular repolarization), QT interval, and overall cardiac electrical activity.
Identifies
Arrhythmias (atrial fibrillation, tachycardia, bradycardia), myocardial infarction (heart attack), ischemia (reduced blood flow to heart), left/right ventricular hypertrophy, heart block, pericarditis, electrolyte imbalances affecting the heart, and pre-existing heart conditions.
What is the ECG Test?
An ECG (Electrocardiogram) is a painless, non-invasive test that records the electrical activity of your heart. It detects heart rhythm abnormalities (arrhythmias), heart attacks (current or past), enlarged heart chambers, and electrolyte imbalances affecting the heart. The test takes just 5-10 minutes and provides immediate results.
Why Should You Take This Test?
ECG is one of the most common and important cardiac tests, recommended for anyone with chest pain, palpitations, dizziness, or shortness of breath.In India, heart disease is the leading cause of death. Regular ECG screening helps detect problems early, especially for those above 40 years of age.It is a mandatory pre-surgical test to assess heart fitness before any surgery or procedure.Diabetic and hypertensive patients should get regular ECGs as these conditions increase heart disease risk.Athletes and those starting new exercise regimens benefit from baseline ECG screening.It can detect silent heart attacks that may have occurred without noticeable symptoms.
Who Should Get Tested?
Chest Pain or Discomfort
Rule out heart attack or angina.
Palpitations or Irregular Heartbeat
Detect arrhythmias.
Adults Over 40 (Annual)
Routine cardiac screening.
Hypertension or Diabetes
These conditions affect heart structure over time.
Pre-Surgery Clearance
Required before most surgical procedures.
