    As a medical professional with expertise in cardiology, I can explain what nonsustained ventricular tachycardia (NSVT) means. Ventricular tachycardia (VT) is a type of abnormal heart rhythm that originates in the ventricles, the lower chambers of the heart. When the heart rate exceeds 100 beats per minute and the rhythm is regular, it is considered VT. Nonsustained ventricular tachycardia refers to a specific type of VT that occurs when the heart rate is fast, but the episode does not last long enough to be considered a sustained event. Specifically, NSVT is diagnosed when there are three or more consecutive ventricular premature beats at a rate of over 100 beats per minute, and the duration is less than 30 seconds. The significance of NSVT can vary. In some cases, it may not be a cause for concern, especially if it occurs in a person without any underlying heart disease. However, in individuals with a history of heart conditions, NSVT can be a marker for a higher risk of serious arrhythmias or sudden cardiac events. It is important for individuals experiencing NSVT to be evaluated by a healthcare provider to determine the underlying cause and appropriate treatment, if necessary. read more >>
