ECG Heartbeat Waveform Diagram - Medical Visualization #3364665 (License: Personal Use)

This stylized red ECG (electrocardiogram) waveform displays a single normal cardiac cycle against a neutral light-gray background. The trace includes the characteristic P wave (atrial depolarization), sharp QRS complex (ventricular depolarization), and rounded T wave (ventricular repolarization). Its clean, vector-style design makes it ideal for educational or clinical illustrations where clarity is essential.

Used in medical websites, patient education portals, cardiology blogs, and health apps to visually explain heart rhythm basics; matches user intent for understanding ECG interpretation or recognizing normal vs abnormal rhythms.
