Ventricular arrhythmia is a type of arrhythmia that causes the heart to beat at an abnormally fast rate. If not detected and treated promptly, ventricular arrhythmias can be life-threatening.

Coronary artery disease occurs when the large blood vessels that supply the heart become damaged or diseased. Cholesterol-containing plaques in the coronary arteries and inflammation are often the cause of coronary artery disease.

An ECG records the electrical signals in your heart. It is a common, painless diagnostic test used to quickly detect heart problems and monitor heart health.

Acute myocardial infarction is the medical term for a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is suddenly cut off, causing tissue damage.
