FRIDAY, Feb. 5 (HealthDay News) — When the New Orleans Saints and the Indianapolis Colts take the field for Super Bowl XLIV on Sunday, emotions will be running high, so high that some fans can run the risk of a heart attack and even death.

January 26, 2010

TUESDAY, Jan. 26 (HealthDay News) — When drug therapy can’t control the dangerous heart rhythm disorder called atrial fibrillation, burning out the cardiac tissue responsible for the abnormality will do the job in most cases, a new study has found.

Called catheter ablation, the burning technique ended episodes of abnormal heartbeat and improved the quality of life over a nine-month period for two-thirds of the people in the study who had the procedure, compared with 16 percent of those who were started on a new drug regimen. Read More
