J.J. Watt Wins Days After Heart Procedure

Watt said that his heart had gone into atrial fibrillation earlier in the week on Sunday morning, just hours before the Cardinals beat the Carolina Panthers 26-16.

"I just heard that someone leaked some private information about me and that it will be reported on today," he said.

"On Wednesday, I went into A-Fib. On Thursday, my heart was shocked back into rhythm, and today I'm playing. That’s it."

A nurse who works in cardiac surgery said, "People who don't work in health care don't understand how common this can be." 

The Mayo Clinic defines atrial fibrillation as a "irregular and often very fast heart rhythm" that occurs when the upper chambers of the heart beat "chaotically and irregularly."

It can be treated, but it can cause blood clots, strokes, heart failure, and other problems with the heart.

The rest of the sports world breathed a sigh of relief when they heard that Watt would be okay just after his injury.

Robert Griffin III, a quarterback who is a free agent, said: "Life is bigger than football. Glad you are OK."

Watt said that his heart started beating "weird" on Wednesday, which prompted him go get it checked out. But by Friday, he was back at practise and ready to play again.
