Hello. Everyone , Had my Pacemaker fitted 5 weeks ago . Last Friday I had to have the settings adjusted as heartbeat was too low at 52 now set at 60 bpm . I'm also on Bisoprolol 6.25 but still get occasional palpitations, hope the dose doesn't get increased because of the side effects I struggle with .My biggest concern is the breathlessness which happens after about 50 yards of walking . I was hoping after the pacemaker was fitted this would improve or am I being impatient, and maybe this will improve after a period of time . I have asked but the answer was maybe. Just wondered if anyone had experience of this.
