ECG Waveform Diagram - Understanding Heart Rhythm Basics #3379860 (License: Personal Use)

This minimalist black-line illustration depicts a standard single-lead electrocardiogram (ECG) waveform, featuring the characteristic P wave (atrial depolarization), sharp QRS complex (ventricular depolarization), and rounded T wave (ventricular repolarization). The transparent background ensures seamless integration into medical educational materials, digital interfaces, or clinical presentations. The clean vector style supports scalability without loss of clarity.

Commonly used in medical textbooks, online health education platforms, telehealth dashboards, and patient-facing apps to explain heart rhythm basics. Matches user intent for learning ECG fundamentals, preparing for exams, or visualizing cardiac activity in digital health tools.
