This medical illustration depicts a realistic human heart with visible atria, ventricles, aorta, pulmonary artery, vena cava, and coronary arteries/veins wrapped in epicardial fat. A red ECG waveform runs horizontally behind the heart, symbolizing electrical activity and rhythm. The image uses color-coding-red for oxygenated blood pathways, blue for deoxygenated-to enhance clarity and educational value.

Used on health education websites, cardiology resources, anatomy learning platforms, and patient information pages to explain heart structure, function, and diagnostics like ECG interpretation. Matches user intent for visual learning, medical reference, or clinical training support.
