I had the same sort of experience, in Nov 2017. I went to my Doc with a slow heartbeat, 45bpm. He ran an EEG trace, took one loot at it and sent me to the local, small town hospital ER. They decided that I needed a pacemaker. There were only two beds available at hospitals that installed pacemakers south of Portland, so they sent me to a cardiac speciality clinic at the big hospital in Eugene, OR. This was in the early weeks of the 2017 - 2018 flu season, which was another big year in the NW.
I am doing well, hardly know I have a pacemaker keeping my heart beating normally.
Well, I'm glad you are doing well. My symptoms were heart palpitations, headache, weakness, shakiness, pains in my legs, headache, and my blood pressure was up. I knew something was wrong. It had started slow, and gradually got worse, and after about two weeks I called my family doctor. He was on vacation, and the office suggested I go to the emergency room. That's when they discovered my electrolytes were out of whack. Of course they first checked my heart because of the palpitations, but it wasn't that. They pumped me full of saline, and large quantities of potassium and magnesium. I don't think I've ever felt so crappy in my 72 years of life. I would rather give birth than go through feeling that way again.
