@wcuro The answer to that question really depends on your cardiac health in general, and likely the best answers would come from the doctors who know you and your history. Non-sustained ventricular tachycardia (NSVT) is defined as 3 or more rapid beats originating from the ventricles, is self-limiting and lasting less than 30 seconds. It can be considered as a benign condition if the NSVT occurs infrequently in a healthy heart, or as a potential indication for other problems if it occurs, especially frequently in people with cardiac conditions ( such as cardiomyopathies, coronary artery disease).

Generally, ventricular tachycardia (VT) is considered significant if it lasts longer than 30 seconds, and from what I've read, seen when patients experience these longer VTs is when there's talk of implanting defibrillators to shock them out of future events of VT and hopefully prevent them going into ventricular fibrillation, which is often fatal if it's not stopped. Here are a couple of links to excellent articles about NSVT:
