Hey! Yes, I have experienced that in the past, but it is really rare for me these days. From what I understand a palp is capable of triggering a little SVT or NSVT episode. However these are also benign in a structurally normal heart. If it starts suddenly and stops suddenly, that is probably what it is.
2-8 minutes aren't a bad episode. I use to get them from anywhere from 2-6 hours.They would start suddenly. It would feel like a race car had been set off in my chest and then suddenly it would just calm down. I could actually fell it start and stop in my chest. Weird sensation. It wouldn't hurt telling your doctor about them since they are new for you.
In fact I would encourage you to do that. He might want you to wear a holter just to pick up the rhythm to make sure what it is but don't get too upset. It doesn't sound like a big deal from my own experience. I use to have them on and off for about 4-5years. Then they just stopped. I never took any meds for the condition. I just let them run their cycle. In the past 2 years, I might have had 3-4. THe longest lasting 20minutes and most only a couple of minutes.
They will NOT cause SCD or V-fib in a structuraly normal heart. This has been a question asked on the heart forum at MED Help a number of times and the cardiologist always says it will Not cause that.
Hope that helps and gives some reassurance. Again tell your doctor because it is new for you and they will want to make sure about the rhythm, but don't worry.
