Hi,
I was prescribed bisoprolol for really bad palpitations (thousands of ectopics per day on bad days) and it has worked very well together with stress management, attention to diet, cutting caffeine etc. I was on 2.5 mg a day and now on 1.25 mg a day. I felt a bit woozy for a couple of weeks and it took a few months for full effect, but am fine now, and can exercise, jog, and generally get on with life ok. Propranolol didn't work for me so I was prepared for this beta blocker not to help either - but it really has.
Palpitations have been my main perimenopausal symptom though it took referral to a cardiologist to acknowledge the connection.
Hope this helps and you find relief with them.
(I'm new to posting and this forum is wonderful by the way!)
