Understanding Heart Anatomy and ECG Readings | Cardiovascular Health Guide #3482291 (License: Personal Use)

This medically accurate illustration depicts the human heart with major arteries and veins-including the aorta, pulmonary artery, and vena cava-rendered in realistic colors and textures. Superimposed is a red electrocardiogram (ECG/EKG) waveform representing ventricular depolarization and repolarization, visually linking physiological structure to electrical activity. The image emphasizes clinical relevance for diagnosing arrhythmias, ischemia, and other cardiovascular conditions.

Used on medical education websites, cardiology clinic pages, or health blogs explaining heart function, ECG basics, or symptoms of heart disease; targets users seeking visual aids for understanding cardiac diagnostics and anatomy.
