Ventricular flutter and tremor in the elderly

Ventricular flutter and ventricular fibrillation are serious ectopic rhythms, and the ventricle loses its effective overall contraction ability, but is replaced by fast and uncoordinated fibrillation of each heart muscle. The hemodynamic effects of both are equivalent to ventricular arrest. Ventricular flutter is often a prelude to ventricular fibrillation and is often a fatal arrhythmia before death.
