I really enjoyed your article. I also get the occasional "missed beat"/palpitation. Mine only occur 0-3 times a day and have never been seen on a EKG. Nevertheless it was enough to trigger panic attacks in me and send me to the hospital with heart attack symptoms. Since then I've finally started taking medication for anxiety and no longer stay up all night thinking my hearts going to stop in my sleep so that's nice.

During that time though, nothing I read and nobody explained to me what keeps the heart beating despite all manner of possible failures. 10/10 was definitely worth the read.

The symptoms of a heart attack and a panic attack are annoyingly similar. Whereas people qualified to diagnose and treat one are generally nowhere near the people qualified for the other.
