Doctor gives opinion on what Harbaugh’s heart procedure may be

I’ve been in contact with a doctor, asking him what this minor heart procedure for Jim Harbaugh might be. The doctor wrote back, stressing that this is a rough guess based on very limited data. He wrote:

“Could be a pacemaker. Doubt it is a catherization procedure, no one would consider that minor. Could be a cardioversion, where they use electrical current to change an irregular atrial rate to a regular rate.”
