rate response settings with Boston Scientific
I am 72 and am very active using a variety of aerobic activities. I am a long time swimmer and swimming coach.
I had a Medtronic device implanted 12/18. The rate response worked off an accelerometer only. It did not work well for swimming, biking, paddling etc. After numerous tweaks, it worked ok for running, hiking and some other things and if I tapped on it, it sort of worked in the pool.
In April, I broke the atrial lead and felt awful. My new EP who is very tuned in to active older people, said this would be a good time to change to a Boston Scientific with the micro-ventilation and motion sensors.
I am curious to know if anyone can tell me how the mv sensor works. Is it respiration rate? some blood chemistry thing? CO2 level?
Since my surgery, I have had very positive results with biking and hiking. My bike mph is typically in the 14s where for the past five years or so it's been in the 13s. I feel very positive about hiking. In the pool, however, I do not feel great. I am not working that hard yet but there are many measurements that I am sensitive to that indicate I am well off form. My respiration rate is, of course, a product of my stroke rate. Curiously, if I kick on my back when I can breath at will, my times are as fast or faster than before I broke the lead. If the MV works strictly off respiration rate, it seems that might explain how I'm feeling.
I have an appointment Thursday for possible tweaking so maybe there is something they can do. If anyone has any information that might help me, I would really appreciate the input.
