Just found this study on possible non-invasive treatment for PVCs. Study results do not seem to have been published yet, maybe its still in progress. I'm very interested to know the results. I notice that I often experience ectopics after drinking hot tea within minutes of ingesting. Considering the fact that it takes tea at least 20 minutes to enter the bloodstream leads me to think that it must be vagus nerve stimulation that's triggering the ectopics. Anyway, here's the link. I'd be interested to know your thoughts.

All the best.
