 A group of four or more consecutive PVCs.

 Characterized by abnormal QRS complexes that are not associated with P waves.P waves, if present, may be hidden in the QRS complexes.

 VT may be paroxysmal or sustained for minutes or hours and may lead to ventricular fibrillation.

 The ventricular rate may be slow (slightly above normal rate) or fast (up to 200 beats/min).

 The QRS complexes may be monomorphic or polymorphic.

 SV is decreased especially if the ventricular rate is high, and this results in a lower cardiac output and/or hypotension.
