Clint you and your will be in my prayers. I went thru a something like that a few years back. I was told there is a sack in the middle of the heart that controls the electrical part of the heart beat and for some reason mine got to miss firing. There are drugs that they could have put me on but lots or side effects and pricy. We took the wait and see road , I still have them sometimes but not as bad or as often. It is scary it feels like a bird in your chest trying to take off and spikes your blood pressure.
