Understanding the EKG becomes much easier when you stop memorizing waves and start thinking about physiology. In this reel, I walk through the cardiac cycle and layer the ECG directly on top of it — so each deflection actually means something. • P wave → atrial depolarization (atrial contraction follows) • PR segment → AV nodal delay and ventricular filling • QRS complex → ventricular depolarization (mechanical systole begins) • ST segment → ventricles fully depolarized and ejecting • T wave → ventricular repolarization and relaxation When you connect electrical events to mechanical events, the ECG stops being a pattern-recognition exercise and starts becoming a story of pressure changes, valve movement, and blood flow. Think physiology first. The tracing will follow. #ekg #ecg #heart #cardiology #healthcare
