I have just had a MIBI scan and was required to stop Bisoprolol 48hrs before the scan.
I take 1.25mg per day to treat occasional tachycardia attacks which started a few months after a heart attack. That was 6 years ago, I'm 71 now, still very fit, I jog and cycle, gym regularly, play 18 holes of golf no problem.
Unfortunately, taking Bisoprolol dropped my already low pulse to about 45 resting (I also find it impossible to get my HR above 130 even when working out hard at the gym) and my BP is about 115/65.
Since stopping the Bisoprolol a few days ago my HR has gone up to 50 and BP up to 122/66, and no tachys yet....so I'm tempted to try carrying on without it.
It will be weeks before I see a cardiologist to go through the MIBI results, and getting an appointment with my GP also takes weeks....so I'm tempted to make an executive decision pending my next cardio appointment.
So far I feel fine, but my HR monitor at the gym shows my HR going quickly up to 135, so I backed off my normal workout to stop it going any higher, chickened out I guess after all those years at 125.
Has anybody gone through a similar exercise, preferably under doctors supervision and give me some advice?
