@walkinggirl I have traditionally had low heart rate and recently developed a-fib. The pacemaker was necessary so I could take Sotalol for the a-fib without lowering my heart rate more since my normal was between 50-55 bpm. I suffer from anxiety from time to time and this has been the worst. I will get better and I am talking with someone. I felt a support group with others who have experienced similar would be beneficial.
