I have been experiencing what my cardiologist calls “benign” arrhythmias for 2 years. They come and go, and I am unable to link them to any activities, foods or medicines. We’ve tried digoxin and beta blockers, which didn’t work. He says he can fix them with ablation and a pacemaker or just leave them alone for now. Sometimes they make me lightheaded and I get frightened. Do you think I should do the procedure?
