Hello. I am sorry to hear about the irregular hearts beats at night. I was born with a serious heart condition and have dealt with SVT, Afib, PVC'S, etc... on and off throughout my life, yet it can still be scary to me sometimes when an occurrence happens, so I can just imagine how it would make you worry. Good news. I have had 2 Ablations and have got both SVT/Afib in check. With that said yes you can have shorts burst's of Afib. I actually use to have consistent 5-30 sec bursts. The interesting thing....guess what part of day they would be worst? AT NIGHT!!! The answer one of my Doc's gave as to why they can present worse at night is due to the heart starting to relax compared to it working "normally" during the days hustle and bustle. It can unfortunately be hard to catch or diagnose with it being so sporadic, I would recommend getting a in depth cardiovascular exam if they persist, even if it is sporadic. Do not stress to much though brother. I am 34 and in pretty good health, even with my extensive heart issues. Just try not to let it paralyze you or anything like that, from staying active!!! I hope my long winded response helps. I am not Doctor or anything, but being born with heart disease and having a thirst for knowledge I would say I am a "civilian expert" on the heart. feel free to reach out anytime!!! Stay strong.
It's hard to distinguish whether it's afib , pvcs or pacs without a monitor on your chest. Ekgs only detect them in a short few second session. Of course which most of the time they won't show up.
I don't have much to add that the others didn't except to say if coughing helps cough sooner and if you notice gas or acid reflux try antacids. Regardless what the medical community says I get premature beats from gas in my stomach and a lot more if I have acid reflux so there is a connection. I am not sure why but there is.
