State Sen. Jim Whelan announced today that he has had a pacemaker installed to address an irregular heart beat.

Surgeons from the University of Pennsylvania Hospital installed the pacemaker on Thursday, two years after the Democrat from Northfield received a less invasive treatment for the condition.

"While that worked for a while, recently the problem returned and the doctors recommended a pacemaker to keep my heart in rhythm," Whelan said, in a written statement. "I am grateful to my doctors."

Whelan was discharged today and is not expected to miss any upcoming legislative sessions.
