Sudden Cardiac Arrest (SCA)

Sudden Cardiac Arrest (SCA) is an abrupt loss of heart function causing blood flow to stop. It occurs when the heart's electrical system malfunctions, leading to an irregular, often rapid rhythm called arrhythmia. Without prompt treatment, such as an electric shock from a defibrillator, SCA can result in death within minutes. It’s different from a heart attack, which involves blocked blood flow; SCA is a sudden failure of the heart’s ability to beat effectively. Immediate action is crucial to restore normal rhythm and save lives.
