Pulseless Ventricular Tachycardia

Pulseless ventricular tachycardia is defined by several criteria. First, the heart rate is usually greater than 180 BPM per minute and the rhythm usually has a very large QRS complex. Second, the patient heart rhythm is pulseless. Third, the rhythm originates from the ventricles. All Ventricular Tachycardias are not pulseless. Pulseless Ventricular Tachycardia occurs because there is no cardiac output and because the ventricles cannot effectively pump blood from the heart. If not intervened on time, most of tachyarrhythmias turn to pulseless tachyarrhythmias.
