Normal ECG Heartbeat Waveform - Medical Visualization #132439 (License: Personal Use)

This image displays a simplified but anatomically accurate electrocardiogram (ECG) waveform representing normal sinus rhythm, with distinct P waves, QRS complexes, and T waves. The black line contrasts sharply against a smooth yellow-to-orange gradient, enhancing readability for educational or clinical presentations. It serves as a universal visual aid for illustrating heart electrical activity in digital health resources.

Used on healthcare websites, telemedicine platforms, medical training modules, and patient education materials to illustrate normal cardiac function; matches user intent for understanding ECG basics or verifying rhythm interpretation.
