ECG Heartbeat Waveform Illustration | Medical Diagram Resource #3579806 (License: Personal Use)

This vector-style ECG (electrocardiogram) illustration displays two complete cardiac cycles with clearly defined P waves, sharp QRS complexes, and smooth T waves. The black line on a neutral background emphasizes diagnostic waveform morphology without clinical noise or gridlines, making it suitable for educational and informational contexts. The design prioritizes clarity and anatomical fidelity for non-clinical use.

Commonly used in healthcare websites, patient education portals, medical textbooks, and digital health apps to visually represent normal heart rhythm; matches user intent for understanding basic ECG interpretation or illustrating cardiovascular health concepts.
