ECG of normal sinus RYTHHMS -- On an ECG, a normal sinus rhythm is characterized by a heart rate between 60-100 bpm, a regular rhythm, a P wave preceding each QRS complex, and a normal PR interval. •Rhythm: The heart beats regularly, with consistent intervals between each beat. •Heart Rate: The heart rate falls within the normal range of 60 to 100 beats per minute (bpm). •P Wave: A P wave should be present before each QRS complex. The P wave should be upright in leads I and II, and inverted in l

PVC to NSR: A risky cardiac rhythm shift! 🚨 PVCs can trigger VF or TdP 📉 due to re-entry or triggered activity. ECG: PVC → short runs → TdP → DC → NSR ❤️. Unchecked progression risks sudden cardiac death! ⏰ Early assessment is key. #CardiacRhythm #ArrhythmiaRisk | Abdallah Othman
