Sorry, hit the key before I was finished. There can be missed or skipped beats in a healthy heart too.
In my case, I had to run to the doctor's office while I was having the attack. The ekg picked up SVTs. But it had to be caught during the attack.
Hi! My heart tests were always wonderful. Nothing showed with the event or Holter monitors. If they can, have them check your SA node...if there is a test for that. It's your atria's electrical system. My pacemaker is doing about 70% of my SA node's work. but less than 1% of my VA node's work. Which means my ventricles are doing their own work...not so much my atria.
