ECG Waveform Illustration - Medical Heart Rhythm Diagram #3632626 (License: Personal Use)

This illustration represents a simplified electrocardiogram (ECG/EKG) trace of a normal sinus rhythm, featuring characteristic P waves (atrial depolarization), sharp QRS complexes (ventricular depolarization), and T waves (ventricular repolarization). The line ends in a solid electrode dot, suggesting connection to monitoring equipment. Rendered in maroon on a transparent background, it’s suitable for digital overlays and educational graphics.

Commonly used in healthcare websites, medical blogs, telehealth platforms, and patient education materials to visually explain heart rhythms, arrhythmias, or basic cardiology concepts. Matches user intent for understanding or illustrating how an ECG works.
