Electrocardiography (ECG / E.C.G)
Electrocardiography (ECG or E.C.G) is a non-invasive test that records the heart’s electrical activity. It helps doctors diagnose heart rhythm problems, coronary artery disease, and other cardiac conditions quickly and effectively.
Types of ECG
- Resting ECG
- Exercise / Stress ECG (TMT – Treadmill Test)
- Holter Monitoring (24–48 hours continuous ECG)
Uses of ECG
- Detection of abnormal heart rhythms (arrhythmias)
- Diagnosis of coronary artery disease (angina, heart attack)
- Monitoring heart attack damage or previous infarctions
- Detecting electrolyte imbalances
- Evaluating pacemaker function
- Routine cardiac health monitoring and pre-surgical check-ups
Advantages
- Quick, safe, and painless procedure
- No radiation exposure
- Provides immediate diagnostic results
- Vital for emergency cardiac care
