I've been given a date for an ablation for my SVT. I'm very scared of what to expect. I've been told all the risks which slightly scare me especially the risk of damaging the heart 's pacemaker and having a pacemaker fitted. I know everything comes with risks - like crossing the road. I'm hoping to have an ablation for my flutter and PAF later next year too. I've also been told I will be taken off my meds (2.5 bisoprolol) right after. This frightens me as it stops me feeling lightheaded and lessens the severity of the palpitations. I'm 38 and was diagnosed April last year and have been told the earlier I have the ablation the better it will be. Any advice please???
