Preventing unnecessary loss of life... Sudden Cardiac Arrest
Sudden Cardiac Arrest — SCA is a sudden or unexpected cessation of heart function, most often caused by a sudden arrhythmia, such as ventricular fibrillation (VF). When this occurs, the heart’s electrical impulses suddenly become chaotic and ineffective. Blood flow to the brain abruptly stops and the victim collapses and quickly loses consciousness. Death usually follows unless a normal heart rhythm is restored within minutes.
