I will actually see the EP doc in two weeks, 5 1/2 months after implantation. I plan to ask my settings be optimized for exercise. I have also started running, and will be cycling when the weather gets better. I have a BiV CRT because of persistant bradycardia and an EF of 50%. The rate settings are 60-130, which Ipresume are the default settings. When I run/jog, my HR gets to 130 and my Garmin watch is calculating my VO2 max at 28, which gives me a fitness age of 69. As I am only 62, I would like to improve on this.
My questions are: will raising the upper limit increase my VO2 and or fitness level? Or do I just need to keep training? Or am I too old and fat, and just a lost cause?
