Medtronic Revo limitations

I'm 47 and had AVR replacement last August via Ross Procedure. Heart block post surgery resulted in Medtronic revo pm. I'm active but have been frustrated with the drop in heart rate during exercise. EP says he raised the setting to as high as it goes (he says 160 is the limit on this model). I'm dropping hr at 130. Going back tomorrow. He's talking replacement of the pm. We're taking it slow but would like input?

I would try a lot more tweaking settings before talking about replacing the pm! If he's out of ideas, get another opinion before having another surgery.

I thought most of them maxed out at 180 but I could be wrong.

I'm not sure what you mean by dropping hr?

With heart block, usually the atria beats normally, all we need is for the pm to kick in and pace the ventricles when they don't beat in sync with the atria. If your upper limit is 160, then you should be find as long as your atrial rate is under 160. For working out, practically this means keeping your rate around 150-155 so you have a cushion. My max is 180. Sometimes my atrial rate got over that working out so I went on a low dose beta blocker to keep my rate down rather than get a pm that goes higher (Medtronic has one that does 220). We decided that at my age, I don't need to be higher than 180 while working out anyway.

Yesterday was my first day mountain biking after my implant. I wiped out several times and everything is fine. There are sports after pacemakers!
