Does anyboody have experience with a pacemaker that paces the heart too fast - ie, significantly faster than needed for the activity at hand and/or faster than the heart is used to? What are the sensations you have experienced.
I ask because I have swum a mile or more three times a week for over 50 years and also spent several decades on beta or calcium channel blockers while dealing with paroxysmal atrial fib. The result was an ultra efficient heart, a resting pulse in the high 40s - low 50s and a maximum rate of 100 while swimming. Now my pacemaker is set to 100 for most activities. I find it disconcerting.
Anybody been there, done that?
