Thanks, jc76. Your exercise mode is what they call breathing sensor on my device. Unlike you I only have a PM, not an ICD. Not that I even know what that means.

When I was at the ep last time they set the breathing mode to 16 (the highest rzte), then he walked me around the office to see how I felt with that setting. Felt exhausted. So then they set it back to 10 (where it had been), we walked around, and I felt better.

Next time I’m going to ask him to set it back further to see if it makes a difference in everyday functioning, as the walk around the office doesn’t always yield the best ideas. Then might even consider having it turned off. Fortunately this ep is willing to see me once a month till we can hopefully get me straightened out.

Yet there are so many other variables to deal with on this device. I find that what I’ve been doing is calling Boston Scientific every time I get a new piece of info ( like what you just told me about turning off your exercise mode) and throwing out a new question at them.

It’s all I can do. I would like this PM to work at optimum level.

Thanks again for your input.
