I am so happy that I got a second opinion from a well known EP doctor. I have been on Diltiazem for 1 year with few Afib episodes, I have no other medical problems other than Afib. This new EP told me to stop taking Diltiazem, continue a healthy life style and see him in 1 year. He also told me I should start taking an anticoagulant when I turn 75 years old. I feel so much better being off medication!
