Ok, So I've been feeling like I was going to have an episode of PSVT for a couple of weeks now and I finally did. I jumped up to my usual about 220 BPM. I was able to self convert after about 20 minutes or so. The thing that has been different lately, is for the last few episodes when I go back into NSR, I don't go back to my usual 70 or so BPM, but stay up around 120 to 140 BPM for about a half an hour to an hour. As I said, this has happened for the last three or four episodes but never before. Is this something I should check with my doctor about or is it pretty much run-of-the-mill? Any feedback will be appreciated.
