Hi everyone. I'm 57 and fairly active. I just got my pacemaker implanted on April 24 (for an AV block Mobitz 2). I've definitely noticed a big improvement. However, I still experience "skipped" beats sometimes, usually when I'm doing something strenuous (going up stairs or working out). I also have started to experience light headedness if I get up abruptly. Do I need to have my pacemaker settings adjusted? If so, do you have any advice on what the settings should be? Thanks!
