A second cardiac arrest that began with asystole was followed by ventricular fibrillation. |
This was no easy arrest to manage, as the heart rhythm alternated between ventricular fibrillation and asystole. |
Death resulting from hyperkalaemia may be due to asystole, ventricular fibrillation, or a wide pulseless idioventricular rhythm. |
In one case, the mutation led to acquired torsade de pointes and ventricular fibrillation. |
Defibrillators treat ventricular fibrillation by delivering an electric shock to the chest, and so indirectly to the heart. |
As hypoxemia supervenes, the patient becomes comatose and death may result from ventricular fibrillation or asystole. |
