Abstract
Ventricular tachycardia (VT) is generally a severe arrhythmia that often impairs heart function considerably and may be a precursor of ventricular fibrillation. We distinguish the impact of VT on haemodynamics and on prognosis.
The haemodynamic response to VT depends on the preexisting left (or right) ventricular ejection fraction and the rate and duration of tachycardia. The worse the ventricular function and the faster the rate, the worse the ventricular filling and output are. A VT of long duration (minutes to hours or even days) generally leads to a further haemodynamic deterioration.
The prognosis of VT is determined by the type and severity of the underlying cardiac disease.
