Jim Harbaugh: Cardiologist said I have 'the heart of an athlete'

Los Angeles Chargers head coach Jim Harbaugh received a glowing review from his cardiologist after experiencing an episode of atrial flutter in Sunday's win over the Denver Broncos.

"Just talked to the cardiologist before I came in here," Harbaugh said Wednesday. "Got some test results back. 'The heart of an athlete' is the direct quote from my cardiologist. So, that made me feel good.

"He said the stress test was really good, too. I think he used the word 'incredible.' I think he did. My stamina was incredible and heart got stronger as it was more stressed. Back in rhythm. Hopefully that sticks."

Harbaugh briefly exited Sunday's game against the Broncos after experiencing an irregular heartbeat on the sideline. He's wearing a heart monitor for the next two weeks and taking a blood thinner to prevent another episode.

The Chargers coach has dealt with the issue before, previously noting he experienced an irregular heartbeat during a game while he was head coach of the San Francisco 49ers.

The 60-year-old has led L.A. to a 3-2 record so far this season.
