"Twitching/clicking" in chest with exertion
Hello! I'm a 67-yr. old female, with a Boston Scientific Accolade L301 PM (got it in June 2018), implanted on my right side (first PM was a St. Jude Zephyr DR #5820, implanted in Aug 2011, diagnosis: bradycardia/sick sinus syndrome). I've been feeling what I'll call "twitching or clicking" in my chest, left side, primarily during execise/exertion. Example: felt it during most of my morning 2.5-mile walk today, on hilly terrain. Doesn't hurt, but is VERY noticeable. More concerning is that when I'm done with the walk, I'm spent and want to just crash and take a nap. Ditto after, say, 1 hour of a yoga class, or after some laps in the pool. I'm generally fit (have exercised regularly most of my life) but since my first PM, it seems I've had to "push" through more and more and the "twitching/clicking" has definitely increased. PM techs have never heard of anyone feeling such "twitching/clicking" and look at me like I'm nuts. But, the zapping of energy is now really bothering me and I'm wondering if I shouldn't be exerting myself... My monitor indicates the PM is working properly so we're all stumped. Has anyone out there ever experienced something similar? Can you shed any light?
