Thank you, i had another strange episode today but im not sure if it was cardiac or.anxiety. i also get a lot of pacs, usually very mild like a small hiccup in my chest at the top part of my heart, but sometimes they happen a lot and are bothersome. I also have where i get my right ear pulsing to my hea
rtbeat a lot. :( any ideas??
SVT starts and stops on a dime. It doesn't gradually build. That said, I had instances where I could feel the SVT commence while I stll could feel a normal pulse underneath it. But within 10 seconds, the SVTwould completely take over. I hope you find an answer. Don't give up!
It depends, i know ive had svt twice. Started very suddenly and seemed to fizzle out at the emergency room. Other times, it just happens slowly and gradually i can feel it building up and i have to lay down very quickly and drink water or it becomes full blown. Im just so sick of this. :( he caught a few episodes on tape and said it was sinus rhythm just 160 bpm so thats where he came up with the ist. :(
IST is rare, so your odds of having some more common like SVT are in your favor. I'd talk to another electrophysiologist, get a second or perhaps a third opinion. I don't believe a formal diagnostic criteria exist for IST. Rather, all other possibilities are excluded; sort of a back door diagnosis.
Do go from a normal resting heart rate to this super fast pulse seemingly in an instant? How do these episodes manifest themselves?
I should mention my potassium is normal now.
