MESA, Ariz. — Cubs reliever Brad Wieck underwent surgery Monday to prevent the recurrence of an atrial flutter, an abnormal condition of the heart.
Wieck, 28, who posted a 3.60 ERA in 14 appearances after being acquired in a trade in July, returned Wednesday to Arizona and will rest through at least the rest of the week, the team said in a statement.
Team doctor Stephen Adams diagnosed Wieck with an abnormal heartbeat via an electrocardiogram during an examination earlier this month. After consultation with a cardiologist, Wieck underwent a cardiac ablation.
Wieck is expected to be evaluated toward the end of next week to determine a timeline for resuming pitching duties.
Former Cubs infielder Mark DeRosa underwent a similar procedure in late February 2008 and was ready by the start of the regular season.
DeRosa’s condition wasn’t considered life-threatening, but he elected to undergo the procedure to prevent the fluttering from recurring. He passed up the option to take medication for his condition.
