Los Angeles Chargers head coach Jim Harbaugh had a health scare during Sunday's win over the Denver Broncos. Harbaugh, in his first season coaching the Bolts, had to leave the sideline surrounded by training staff in the first quarter of the game in Denver. The move caused immediate concern among NFL fans, who were waiting for an update on the coach's condition.

Fortunately, Harbaugh was okay, and eventually returned to the sideline after having defensive coordinator Jesse Minter serve in his place for a period of time. The head coach later revealed he suffered an "atrial flutter," an abnormal heart rhythm that causes the upper chambers of the heart to beat too quickly. On Wednesday, Harbaugh delivered the positive test results he received from his cardiologist to reporters in classic Harbaugh fashion.

"So that made me feel good. Said the stress test was really good, too. I think he used the word incredible.

I think he did. Said my stamina was incredible and got stronger as it got more stressed. Back in rhythm.

Hopefully that sticks. Got the monitor on, so good news. I took it as a compliment.

Blue twisted steel." Harbaugh, who has the Chargers off to a 3-2 start, told reporters earlier in the week he will wear a heart monitor for two weeks and take prescribed blood thinners to control his heartbeat. Los A.
