Heart & Circulation

See how the heart pumps and exactly what each condition changes — in interactive 3D with a live ECG — then find care.

Conditions in this section

• Heart Attack & Coronary Disease — A blocked artery starves the heart muscle — the world’s leading killer, often survivable if treated fast.
• Heart Failure — The heart can’t pump strongly enough for the body — but modern medicines have transformed the outlook.
• High Blood Pressure — The “silent killer” — persistently high pressure that quietly damages the heart, brain and kidneys.
• Atrial Fibrillation (AFib) — The heart’s upper chambers quiver instead of beating — an irregular rhythm that raises stroke risk.
• Heart Valve Disease — A valve that won’t open fully or leaks — including rheumatic disease, still common in India.
• Sudden Cardiac Arrest — The heart abruptly stops — a true emergency where immediate CPR and a defibrillator save lives.
