| The resultant irregular rhythm may be difficult to differentiate from atrial fibrillation. |
| Defibrillators treat ventricular fibrillation by delivering an electric shock to the chest, and so indirectly to the heart. |
| Patients with atrial fibrillation also had more drug days for diuretics and for electrolytes. |
| Death resulting from hyperkalaemia may be due to asystole, ventricular fibrillation, or a wide pulseless idioventricular rhythm. |
| Patients should be monitored for an exacerbation of atrial fibrillation or flutter, and for increasing ventricular rates. |
| This was no easy arrest to manage, as the heart rhythm alternated between ventricular fibrillation and asystole. |
