If you're looking for a group of folks who have the kind of atrial fibrillation that you do, check out the StopAfib.org discussion forums. If you are a young afibber, or have valvular afib or hypertrophic cardiomyopathy and afib, or if you're interested in afib and exercise, afib and pregnancy, afib and sleep apnea, or other special topics, join a group to discuss your common concerns.
If you're looking for a local support group, you'll find those, too. We have, or are starting up, local support group discussions for Portland, OR; Phoenix, AZ and the Southwest; Dallas-Ft. Worth; and Boston.
If you'd like to start a group for your locale, just let us know.
