Closed Loop Simulation (CLS)
Hi there. I've read quite a few other posts on this subject but (as everyone always thinks ;-)) none quite match my situation.
I'm a pretty fit and active 62-y-o in England who walks lots and runs at least one and often 2 or more 5km runs each week.
But I'd been really struggling since the Spring. After tests, I was fitted with a pacemaker for total heart block in August. It's a Bitronik. Accoring to the certificate it's model number 407147, but I don't think that is very meaningful?
Felt better almost right away, but noticed that sometimes on long walks I'd sporadically get really out of breath, and yet my heart rate per monitor remained at only 75. The next day I'd do exactly the same walk and in the same sections heart rate would be up to 120-130 and no breathlessness.
I took mountains of stats to my first check-up last month, but to be honest they weren't really interested in them. They said everything was absolutely fine per the data they downloaded from the pacemaker. I asked about CLS and they asked why I was interested. I said that I had read that it could be beneficial for very active people.
They said this is something that they could enable if I wished, but suggested that it would probably be best if I got back to my normal running pattern before deciding. This seemed a reasonable argument.
Actually I am finding it very difficult to get back to full fitness. Until the summer I could easily run 5km, now I am struggling to run for more than a few hundred metres, so I am mixing up the 5km "runs" by alternately walking and running.
Have I misunderstood what CLS might do for me? Where could I read more: the Bitronik papers are very technical and I am not a doctor.
(PS I am a Grade A hypochondriac - is there any simple way to check that the pacemaker is working at all? Apart from not dying, obvs ;-)).

We are very lucky to have these devices.
