A normal ECG (electrocardiogram) shows consistent wave patterns—P wave, QRS complex, and T wave—representing healthy heart activity. In contrast, a heart attack ECG often shows ST segment elevation, T wave inversion, or abnormal Q waves. To check an ECG report, start by examining the heart rate and rhythm. Look for any deviations in waveforms, especially ST segments. Consistent abnormalities in multiple leads may indicate myocardial infarction. Always compare with previous ECGs if available. While basic interpretation helps, ECG analysis should be confirmed by a medical professional to accurately diagnose heart conditions like heart attacks.
