But a new study shows that another treatment may have better results for patients who were not helped by drug therapy.

The treatment is called catheter ablation. Doctors place a long, thin tube called a catheter into the heart. Then they use radio frequency energy to heat the tissue around the catheter. The heat burns off a small amount of heart muscle. The goal is to block abnormal electrical activity in the heart. (read more...)
