Most heart attacks do not lead to sudden cardiac arrest. Heart attacks increase the risk for sudden cardiac arrest.

Sudden cardiac arrest can occur after a heart attack, or during recovery. These two distinct heart conditions are linked. Death occurs within minutes if the victim does not receive treatment. Seconds later, a person loses consciousness and has no pulse. With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat ( arrhythmia). Sudden cardiac arrest occurs suddenly and often without warning. The heart attack symptoms in womenВ can be different than men. Unlike with sudden cardiac arrest, the heart usually does not stop beating during a heart attack. More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. Symptoms of a heart attackВ may be immediate and intense. The longer a person goes without treatment, the greater the damage. If the blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die. What is a heart attack?ДЄ heart attack occurs when a blocked artery prevents oxygen-rich blood from reaching a section of the heart. A heart attack is a вЂњcirculationвЂќ problem andВ sudden cardiac arrest is an вЂњelectricalвЂќ problem. A heart attackВ is when blood flow to the heart is blocked, and sudden cardiac arrestВ is when the heart malfunctions and suddenly stops beating unexpectedly. People often use these terms interchangeably, but they are not synonyms.
