Understanding Cardiac Arrest: Symptoms, Causes, and Emergency Response #17021 (License: Personal Use)

This medical illustration depicts a human heart overlaid with a bold yellow lightning bolt, emphasizing the sudden, catastrophic disruption of the heart’s electrical system during cardiac arrest. Red and blue vessels highlight oxygenated and deoxygenated blood flow, while the strike point indicates ventricular fibrillation or asystole-the most common arrhythmias triggering collapse. The image is designed for clarity in educational and emergency response contexts.

Used on health education pages, CPR training sites, or public awareness campaigns about sudden cardiac death; matches user intent to understand symptoms, differentiate cardiac arrest from heart attack, or learn emergency response steps.
