After eating a light supper, I laid down in my bed on my left side. I heard my heart beating in my ears - that's not unusual. But tonight I heard a missed beat, than a resumed pace. I'd count the number of beats before another missed beat occurred - it was irregular - sometimes 5 beats, sometimes 20 beats - before a missed beat. After the misssed beat I'd feel the next beat in my neck - along the carrotid. Maybe it was an extra strong beat and that's why I felt it, I don't know. I rolled to my right side to see if that affected the beat irregularity; it did not. So now I don't know whether to do something about this tonight or wait til tomorrow before calling my regular Dr. A few miles from my home there is an emergent care (commercial) office - mostly for children's illnesses. Maybe I could go there to get checked out tonight. What do you think?
