Heart Health and ECG Monitoring - Understanding Cardiac Rhythm #3593809 (License: Personal Use)

This black-and-white line illustration features a detailed human heart centered on a continuous electrocardiogram (ECG) waveform, with distinct P, QRS, and T waves representing atrial depolarization, ventricular depolarization, and repolarization respectively. The clean, clinical aesthetic emphasizes the relationship between cardiac anatomy and real-time electrical signaling. It’s ideal for educational or medical content explaining heart diagnostics and physiology.

Used in healthcare websites, patient education portals, cardiology blogs, and medical textbooks to illustrate concepts like arrhythmia, normal sinus rhythm, or heart monitoring technology. Matches user intent seeking visual explanations of how the heart’s electrical system works.
