SOB - New Pacemaker Implant
So I am 52 years old and have a CRT-D. I have had cardiomyopathy for 30 years. EF down to 20% but prior to PM implant (Sep 8 2020) I had a pretty good exercise tolerance. I could sustain 120bpm for 40 mins no problem.
So since I've started exercising, I have ZERO tolerance. Walking uphill (moderate incline) is a struggle. On most moderate hills I have to stop and catch my breath. I feel like my HR immediately skyrockets upon starting to exert myself. Just prior to my implant I was hiking and felt great...It is so aggravating to be SOB. I never experienced it in 30 years with my condition. I went to see my EP after a week for a checkup and he bumped up my HR max to 140 and made some other adjustments (after I told him about my SOB upon exercise). I am frustrated. My muscles feel weak when exercising as well. I'm not an athlete but I thought I could tolerate most moderate exercise for my condition.
I wear a Garmin forerunner which tracks HR. Prior to PM implant my heart rate would gradually increase. Again, now it seems like light to moderate exercise has me maxed out. As soon as I pause my pulse drops quickly. From say 140 to 100. Again according to my Garmin but my breathing seems to be in line with that.
I do have to mention that I feel great otherwise. Palpitations are minimal and I'm not exhausted at the end of the day. No more naps. So its working and probably needs to be tweaked?
What kind of questions should I ask when I see my EP. What is a key setting related to what I'm experiencing? Boston Scientific Device G247 Model. I called the rep from Boston Scientific and he said he would take a look at latest interrogation and come up with a plan along with EP.
Thanks in advance for your help. Its great to have forums like these and support from folks who are experiencing the same issues.
