October is National Sudden Cardiac Arrest Awareness Month, a critical time to raise awareness about a leading cause of death that strikes without warning. Sudden Cardiac Arrest (SCA) is a medical emergency that occurs when the heart unexpectedly stops beating. This leads to a loss of blood flow to the brain and other vital organs, resulting in unconsciousness and, if left untreated, death within minutes. While heart attacks and SCAs are often used interchangeably, they are distinct medical events. A heart attack is caused by a blockage that stops blood flow to the heart, while SCA is an electrical malfunction that causes the heart to stop beating entirely.
