ECG interpretation involves systematically analyzing the waveforms and intervals to assess heart rhythm, rate, and overall electrical activity. This includes evaluating the P-wave (atrial depolarization), PR interval, QRS complex (ventricular depolarization), ST segment, T-wave (ventricular repolarization), and QT interval. A normal ECG typically shows a regular heart rate (60-100 bpm), normal P-waves, a PR interval between 120-200 ms, a QRS complex duration less than 120 ms, and a normal QT int

🚑 Spotting a MI on ECG – Made Simple! ❤️📉 Here's a quick and simple trick using smiley faces! 😊☹️ 👉 Concave Upward (Happy Face 😊) ST Segment? This usually means non ischemic changes . Seen in conditions like early repolarization or pericarditis. 👉 Convex Upward (Sad Face ☹️) ST Segment? This is a red flag! 🚨 It strongly suggests ischemia and could indicate Myocardial Infarction (MI). Seen in ST-elevation MI (STEMI) – a medical emergency! 💡 Remember: The ST segment shape can give you cruc
