Ventricular flutter

Ventricular flutter is an arrythmia affecting the ventricles that can occur in infancy, youth, or as an adult.

Ventricular flutter is mostly caused by re-entry with a frequency of 300 bpm. The ECG shows a typical sinusoidal pattern. During ventricular flutter the ventricles depolarize in a circular pattern, which prevents good function. Most often this results in a minimal cardiac output and subsequent ischemia. Often deteriorates into Ventricular Fibrillation.

It can be induced by programmed electrical stimulation.
