I have had a dual chamber pacer since I was 25. I'm 54 now. Six months ago, my NEW cardiologist shut off the
Ventricular side of the Dual chamber device because the leads eroded & were no longer pacing. Since that event, I have recurring episodes of a strained feeling (tightness) after any type of activity. Sometimes, labored breathing. A recent stress test showed no abnormalities. Nevertheless, I'm always uncomfortable, whether laying down or not. however my cardiologist insists it's my imagination. Does anyone have advice on my options? In this state of NC, there are limited cardiologists. Most doctors have grouped together into one care unit. It's not a simple matter of finding another cardiologist, whereas in my home state of Colorado, most doctors are still independent. I relocated almost two years ago and have regretted moving ever since.
