An Electrocardiogram (ECG or EKG) is a test that records the electrical activity of the heart over a period of time using electrodes placed on the skin. It provides vital insights into heart health.
- Detect abnormal heart rhythms (arrhythmias)
- Identify heart attacks (past or ongoing)
- Assess heart structure issues
- Monitor the effectiveness of heart medications or pacemakers
- Resting ECG: Done while lying still — most common.
At Sachdeva Diagnostics, we only perform Resting ECG. - Stress ECG: Done while walking on a treadmill or cycling
- Holter Monitor: Worn for 24–48 hours to track heart activity over time
- Arrhythmias (e.g., atrial fibrillation, bradycardia)
- Heart attack (current or past)
- Ischemia (reduced blood flow to the heart)
- Enlarged heart chambers
- Electrolyte imbalances
- Drug effects (e.g., digoxin)
