Im sure the cardiologist assessed your pulse before giving you beta blockers, have you tried them?
I was training as a student nurse, but the stress from this has been too much for me to cope with tbh.Im reluctant to take BB because my resting heart rate sits at 60bpm, and tbh theres nothing wrong with my resting hr. I would prefer to have an ablation than take daily unnecessary medication for the rest of my life?
