There could be many other factors involved in it, but an occasional irregular heart rate in and of itself is not necessarily life-threatening. The best thing to do would be to talk to your doctor about it to see what could be the trigger for it.

On the positive side, once I cut back on caffeine, stress, and anxiety, I noticed that instead of getting this sensation 2 or 3 times a day, I now only experience it maybe once or twice a week. Sometimes, I even go weeks at a time without experiencing it.
