Treating an Abnormal Heartbeat
VOAVideo: Treating an Abnormal Heartbeat
This is the VOA Special English Health Report, from http://voaspecialenglish.com/
A condition called atrial fibrillation produces an abnormal heartbeat. People feel their heart race and they lose their breath. It may last a few seconds, but it can get worse and worse with age, leading to a heart attack or stroke. Doctors generally treat atrial fibrillation with drugs. But a new study shows that another treatment may have better results for patients who were not helped by drug therapy.

The heat burns off a small amount of heart muscle. The goal is to block abnormal electrical activity in the heart. (read more...)
