Sudden Cardiac Death. Death resulting from an abrupt loss of heart function (cardiac arrest). According to the American Heart Association, over 250,000 people die each year from cardiac arrest. Cardiac arrest patients are twice as likely to survive in places where defibrillators are publicly available and volunteers have been trained to use them.
Sudden cardiac death. A death due to electrical problems in the heart. SCD is usually caused by ventricular tachycardia or fibrillation. SCD is different from a heart attack, which results from heart muscle damage from blood flow blockage, rather than an electrical problem. SCD is also known as sudden cardiac arrest (SCA).
Sudden cardiac death. the abrupt loss of heart's pumping ability due to rhythm dysfunction(ventricular fibrillation), can cause death within minutes after onset.
Sudden Cardiac Death. Natural death due to cardiac causes, noted by abrupt loss of consciousness within an hour of the onset of acute symptoms. Preexisting heart disease may or may not have been known to be present, but the time and mode of death are unexpected.
Sudden cardiac death. When untreated electrical problems in the heart cause death. Sudden cardiac death is usually caused by heart rhythms that are too fast. This condition is also called "cardiac arrest." Sudden cardiac death is different from a heart attack, which is caused when blood flow is interrupted and the heart is damaged.
