Hi im 19 years old female from scotland, names Abbie Mcginley...Ive been signed off work for 3 months now wil irregulare heart beat and palpitations, also have SVT where my heart normally sits between 120-50bpm, ive been rushed into hospital 4 times with palpitations where ive missed beats or extra heart beats have came on. I got given bisoprolol fumarate 2.5mg, ive been on them for 3 days, 1st day experienced new palpitations where it was a heavy feeling and took bad hot sweats, yesterday was fine and today ive been having the feeling like my hearts going to stop..New kind of palpitations again where i have to jump up to get my heart to a normal rhythm, ive also been sick tonight and very dizzy and shaky, sore head and short in breath, heart rates sitting at 53. Should i stop taking these tablets? I do feel realy unwell and feel like im a pest if i phone NHS 24/7 or my doctor. Anything i can do?

### output:

Dear Amy your symptoms seem to be due to undue awareness of missed beats which is not unusual but in your case very troublesome.bisoprolol can help but sometimes in healthy young people, it can make normal heart beat very slow leading to dizzy/ sweaty spells as you describe. The slowing of normal heart beat can also ironically increase the frequency of extra beats and may seem to make your palpitations worse. I will suggest you stop bisoprolol and try non-pharmacological measures to suppress extra heart beats (they are due to irritable heart often secondsryvto stress). Try Mindfulness meditation and regular aerobic exercise which will help. I am not convinced you have SVT (someone has put a wrong label/ erase it as quickly as you can unless there is irrefutable ECG proof of a sustained SVT documented). Hope this helps
