When Cardiac Arrest Occurs?

What is cardiac arrest? Sudden cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs.

What happens before cardiac arrest?

Warning signs and symptoms can appear up to two weeks before cardiac arrest takes place. Chest pain is most commonly reported by men, while women commonly report shortness of breath. You may also experience unexplained fainting or dizziness, fatigue or a racing heart.

Who is at risk for cardiac arrest?

A personal or family history of other forms of heart disease, such as heart rhythm disorders, congenital heart defects, heart failure and cardiomyopathy. Growing older — the risk of sudden cardiac arrest increases with age. Being male. Using illegal drugs, such as cocaine or amphetamines.
