    Nonsustained ventricular tachycardia (NSVT) is defined as >3 consecutive ventricular beats at >120 bpm for <30 seconds.

    NSVT is commonly seen in patients with congenital heart disease and cardiomyopathy but is rare in healthy children.

    Extended ambulatory monitoring can improve detection rates of asymptomatic arrhythmias like NSVT compared to standard monitoring.

  • 4

    In a study of 2,805 patients, the overall prevalence of NSVT was found to be 6%, with an average detection time of 4.3 days.

    Management changes based on NSVT detection included medication adjustments and potential implantable device placements.
