ECG Heartbeat Waveform Image - Medical Diagram for Health & Science Websites #3395153 (License: Personal Use)

This image displays a stylized blue electrocardiogram (ECG or EKG) waveform on a transparent checkerboard background, illustrating one complete cardiac cycle. The waveform includes the distinct P wave (atrial depolarization), sharp QRS complex (ventricular depolarization), and T wave (ventricular repolarization). Its clean vector-style design makes it suitable for digital use in healthcare, educational, and biomedical contexts.

Commonly used in medical websites, telehealth platforms, health infographics, anatomy textbooks, and patient education materials to visually represent heart activity. Matches user intent for understanding or illustrating cardiac rhythm, diagnostics, or vital signs monitoring.
