This is my first post. I’m also 76 and have had palpitations for years, a dry cough for longer, and lightheaded spells/ shortness of breath for the last six months or so.. Long story short, I finally got a diagnosis for silent reflux (while wearing a 30- day event monitor) in mid-December. It reported a 4.5 second electrical silence on January 1st, and I had a two-lead pacemaker implanted on the 5th. I can’t wait for my healing to get to the point where I can ditch the Velcro brace at night and start getting normal sleep on my left side again. It’s nice to tell this to someone who understands.
