LOS ANGELES -- Los Angeles Dodgers reliever Kenley Jansen underwent a procedure to address his irregular heartbeat Tuesday and the team said he can begin physical activity "without restriction" in about a week.

Jansen, the Dodgers closer for most of 2012, missed time in each of the past two seasons with atrial fibrillation. He had a 2.35 ERA with 99 strikeouts in 65 games and was 25 of 32 in save opportunities.

On Tuesday, Dr. Koonwalee Nademanee performed a catheter ablation on the 25-year-old Jansen. In a roughly three-hour procedure, Nademanee identified the abnormal tissue in the left atrium of Jansen's heart and cauterized it to stop it from generating abnormal electrical signals. The Dodgers said Jansen's heart was beating in a normal rhythm after the surgery.

The Dodgers have said they will attempt to re-sign Brandon League this winter, but if those efforts fail, they likely will turn to Jansen once again as their closer.
