ECG Heartbeat Waveform Icon - Medical Diagnostic Symbol #3863131 (License: Personal Use)

This minimalist monochrome illustration depicts a standard electrocardiogram (ECG or EKG) trace, highlighting the characteristic P-QRS-T waveform of a single human heartbeat. The sharp QRS complex signifies ventricular depolarization, while the smoother P and T waves represent atrial and ventricular repolarization, respectively. The baseline undulations suggest normal respiratory variation or minor artifact.

Commonly used in digital health platforms, telemedicine interfaces, medical education materials, and emergency response graphics to symbolize cardiac monitoring, vital signs, or life support status. Matches user intent for medical visualization, UI icons, or infographics about heart health.
