asystole

[āsis′təlē]
Etymology: Gk, a + systole, not contraction
a life-threatening cardiac condition characterized by the absence of electrical and mechanical activity in the heart. Clinical signs include apnea and lack of pulse. Without cardiac monitoring, asystole cannot be distinguished from ventricular fibrillation. asystolic, adj.

asystole

The form of CARDIAC ARREST in which there is no heart beat and the electrocardiogram tracing is straight. This is in contrast with the other form, ventricular fibrillation, in which the heart muscle is twitching rapidly.

Patient discussion about asystole

Q. WHAT IS CARDIAC ARREST why do people have IT?

A. cardiac arrest is when the heart stops pumping blood. stops working. it can happen in a few cases:
1) it doesn't get oxygen and there for a part of it dies and make the whole heart stopping- heart attack.
2) in electric shock it may cause the electric pulse that generate movement in the heart to stop.
3)from harsh septic shock.
4) from any shock actually :).
