Polymorphic ventricular tachycardia is defined as a ventricular rhythm at a rate greater than 100 beats per minute (bpm) with the QRS complex varying from beat to beat, meaning a heart rhythm disorder (arrhythmia) caused by abnormal electrical signals in the lower chambers of the heart. PVT may appear as a cyclical functioning of the heart and the most common form is twisting of the points. It refers to the shifting of the axis or like the heart is rotating on an axis. PVT usually occurs due to drug toxicity, but can occur as a result of myocardial ischemia. Some episodes of polymorphic VT cause hemodynamic collapse, and some degenerate into ventricular fibrillation.


Therapy may be directed either at terminating an episode of the abnormal heart rhythm or at reducing the risk of another VT episode. The treatment will depend on a further diagnosis of PVT whether stable or unstable. The doctor may tell you to exercise depending on how one tolerates the episodes of PVT. A diet plan and reduction intake of caffeine will be prescribed. If the condition is severe then the doctor may recommend surgery.
