Anyone gone from one lead to two leads? Any changes in athletic performance?
Has anyone gone from having just a single ventricular lead to eventually getting the second atrial lead put in? I was hoping they could share their experiences - especially as it relates to athletic performance.
I got my first PM (a Medtronic Azure XT SR MRI SureScan) about 1.5 years ago. Right now, I have only one lead going to the lower chamber. However, I am an endurance cyclist, runner, tennis player and cannot do stuff to the extent I was able to (which is to be expected.)
Because my lower chamber is beating independently of my upper chamber (due to the single lead), there is asynchrony and the chambers are not contracting in consort with each other. We have been changing the PM parameters a LOT since the PM was put in so that I can bike/run etc. but it still is not that great.
The doctors have said that putting in second lead to the upper chamber will remove that asynchrony and improve my athletic performance. They couldn't put in the second lead when they first implanted the PM because, as they were putting the second lead in, they discovered scarring, etc. This was due to radiation therapy I had to go through for Non Hodgkins Lymphoma long ago, and the docs were not prepared for a little more complicated procedure...and they didn't realize I was such an active person.
Otherwise, I feel good in general with one lead while doing the day-to-day stuff (minus the physical activities.) Anyway, the docs know of a couple of different slightly more convoluted ways to get a second lead in...
However, I had some questions...unfortunately, it's tough to get a doctor's appt right now with COVID, etc. and so am hoping someone here can answer my questions and share their experiences. I am a 53 yo male, 157 lbs and generally in good shape otherwise.
- Once I get the second lead, will my HR be completed governed by my upper chamber? Meaning the UPPER SENSOR RATE setting will really not be needed?
- What postive or negative changes have you felt health-wise?
