Cardiac arrest is too sudden, unexpected and rapid. A person that is experiencing it can only last for less than ten minutes if not properly attended medical attention. It is for this reason that medical attention and procedures are needed to be immediately performed.
The term cardiac arrest pertains to arrest or seizure to the circulatory system under two (2) circumstances, which are (1) ventricular fibrillation; and (2) cardiac shutdown. In the cardiac shutdown or standstill, the heart is motionless and emits no electrical activity, which is seen in electrocardiogram. On the other hand, in ventricular fibrillation, the heart displays a writhing, twisting action, which is signified by the irregular and continuous wave motion in the electrocardiogram. In these conditions, the heart is not expelling blood resulting for the circulation to be completely arrested.
