Ventricular flutter

Overview
Overview
Ventricular flutter is an arrythmia affecting the ventricles that can occur in infancy[1], youth,[2] 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.[3][4]
