Since BB should, in most case, actually lower your heart rate
the bigeminy/trigeminy only at low heart
rates, perhaps expect an increase initially? I've been taking 40mg
of Nadolol for like 20 years and I think that it's a wonderful drug for those of us who suffer from IST type issues and palps that seem to flare up with stress and caffeine and sugar intake, etc.
I've never felt bad when taking this, never had fatigue or anything.
