Hello, I have only posted once before here and am still fairly new to this community. I didn't receive any responses or likes for the first post and so I am wondering if I am doing something wrong and it didn't go out? I guess I will find out if I have any replies or not to this one... Anyway, I have had SVT episodes, and periods of ectopics (PVC's and PAC'S) from time to time over the last 10 years. Still have not found a rhyme or reason for the flare ups after all this time. It's not anything typical like caffeine, etc., however, something that happens occasionally is extremely unnerving to me- a sudden odd heartbeat that lasts for usually around 10 seconds and it feels so strange, like my heart is trying to figure out how to battle it and get back to normal. It leaves me extremely anxious after for a little while and feeling off. Today it happened while I was calmly driving down a side street talking to my mom on the phone. I am hydrated, rested, and relatively stress free ( or was until this happened ). Does anyone have this where you can actually feel it in the throat if taking pulse?
