What is Cardiac Arrest, and how is it different from a Heart Attack?
Sudden Cardiac Arrest occurs when the heart malfunctions and stops beating unexpectedly. Cardiac arrest 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. Seconds later, a person becomes unresponsive, is barely breathing or gasping. Death occurs within minutes if no treatment is provided and survivors can suffer from serious brain damage.
This is different than a Heart Attack. What’s the difference between cardiac arrest and a heart attack?
A heart attack occurs when blood flow to the heart is blocked. A blocked artery prevents oxygen-rich blood from reaching a section of the heart. If the blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die.
