Weird feelings explained
I'm two weeks into my second PM and lead replacement. Since the replacement, I've had some strange feelings that concerned me. One was a sudden warmness that came all over my body when I was on the phone. I didn't get tingly like I was about to pass out, but it was similar in the way that the feeling spread. The other was a slowing of my HR while I was watching TV on the couch. It felt similar to an office PM check where they slow your pacing to test the threshold of the leads.
Like I said, i was concerned because I'd never felt either of these feelings in the years I've been pacing. It turns out the the warmness was related to what they call a retrograde. When the pacing of the ventricle gets ahead of the atrium and starts pacing it instead of the other way around (forgive me if i didn't explain it quite right, but it should be close). The PM rep made a programming change which he says should take care of it.
The other problem felt like my heart was slowing to a stop and then started again. This scared me plenty. It turned out to be a software diagnostic program that I'm told ran 3 times a day. It's function was to preserve the battery life by testing the threshold of the leads. It felt like an office PM check because that's exactly what it was doing. They turned it off and I'm going to live with this a while and decide later if it's worth the feeling to save a bit on battery life. Now that I know what it was, it might be something that I'd be OK living with if it buys me more time between surgeries.
I hope this helps somebody as I had no idea what was going on and feel a lot better now.
Happy Valentines day!
