Complete heart block with Stokes Adams attack from transient ventricular fibrillation.

TOKES Adams attacks with loss of consciousness due to a sudden decline in cardiac output usually occurs in patients with complete heart block. The precipitating event is ventricular asystole, ventricular flutter-fibrillation or a combination of both arrhythmias. Ventricular fibrillation may follow a period of asystole, or ventricular fibrillation may precede a period of asystole. Infrequently the Stokes Adams attack is due exclusively to ventricular fibrillation. Transient ventricular fibrillation was recorded electrocardiographically in a patient with complete heart block and is the subject of this report.
