Non-sustained ventricular tachycardia lasts less than 30 seconds and presents with tachyarrhythmia with more than 3 beats of ventricular origin. When the rhythm lasts longer than 30 seconds or hemodynamic instability occurs in less than 30 seconds, it is considered sustained ventricular tachycardia.
NSVT is defined as an episode of ventricular tachycardia that:2. Involves a heart rate of more than 100 beats per minute. Persists for at least three heartbeats. Lasts less than 30 seconds.
INTRODUCTION. Nonsustained ventricular tachycardia (NSVT) is a common but poorly understood arrhythmia. It is usually asymptomatic and most often diagnosed during cardiac monitoring (eg, continuous ambulatory electrocardiography or inpatient telemetry) or on an exercise test performed for other reasons.
The difference between the two is that in ventricular tachycardia, the lower chambers of the heart are beating much faster than they should but the overall process is happening in the right order. In ventricular fibrillation, the heart's beating process isn't happening in the right order.
VT is defined as 3 or more heartbeats in a row, at a rate of more than 100 beats a minute. If VT lasts for more than a few seconds at a time, it can become life-threatening. Sustained VT is when the arrhythmia lasts for more than 30 seconds, otherwise the VT is called nonsustained.
Nonsustained ventricular tachycardia (NSVT), defined as three or more consecutive ventricular beats at a rate of greater than 100 beats/min with a duration of less than 30 seconds (waveform 1), is a relatively common clinical problem [1].
