ECG Heartbeat Waveform Illustration - Medical Diagnostic Visual #3850355 (License: Personal Use)

This image displays a simplified yet anatomically accurate ECG waveform in bold red against a transparent background. It captures the key components of a normal sinus rhythm: the small P wave (atrial depolarization), the sharp QRS complex (ventricular depolarization), and the rounded T wave (ventricular repolarization). The design is vector-style, making it scalable for digital or print use without loss of clarity.

Commonly used in healthcare websites, telemedicine platforms, medical textbooks, patient education materials, and app interfaces to visually represent heart activity, cardiac monitoring, or vital signs. Matches user intent for understanding or illustrating basic ECG interpretation.
