TUESDAY, Aug. 5 (HealthDay News) -- Light to moderate exercise -- just walking a few blocks or even dancing -- can help prevent the abnormal heart rhythm called atrial fibrillation in those most vulnerable to it -- older people, a new study finds.

WEDNESDAY, July 9 (HealthDay News) -- A gene mutation linked to one family's hereditary form of atrial fibrillation may help researchers find better ways to predict, prevent and treat the heart rhythm problem, according to a new report.

The mutation -- a flaw in the DNA sequence -- was discovered by Mayo Clinic researchers studying a large family with an inherited form of atrial fibrillation in 11 relatives. Collaborators at the University of Iowa later confirmed the mutation's role in altering the electrical properties of the heart through an animal model.
