I have had Lone Cardiac Dysrrhythmias since 11/26/90. I am currently 63 years old and have been taking Lanoxin .25 twice daily and Coumadin 5 miligrams 4 days a week and 2.5 three days a week. I have done this without difficulty for the past 7 1/2 years. I do know that many new ideas and ways to treat this problem must be available at this time. Do you think I should have major review of my condition. I am not having problems but would like to know if a new approach might be helpful.
