The public is invited to a free lecture about atrial fibrillation in Green Valley Thursday morning.

The talk, "Keeping Your Heart in Sync: What You Need to Know About Atrial Fibrillation," is scheduled for 10 a.m. at the Canoa Hills Social Center, 3660 S. Camino del Sol, Green Valley.

Atrial fibrillation is a heart rhythm disorder that affects between 2 to 3 million people and accounts for about one-fifth of all strokes in the United States. By 2050, the number of people affected by atrial fibrillation will increase to an estimated 12 million, Sarver Heart Center officials say. The condition leads to a fast and irregular heart rate.

The presentation is part of the UA Sarver Heart Center’s Green Valley Lecture Series, in cooperation with Green Valley Recreation, Inc. No reservation isrequired. Refreshments provided. For more information about the UA Sarver Heart Center, visit www.heart.arizona.edu
