Kenley Jansen opens up about heart troubles

Kenley Jansen knew immediately what was happening. His heart was racing. His chest was tight. Each breath was a gasp.
The same thing had happened in 2011 and 2012, each time when he was in the high altitude of Colorado. His heart was in atrial fibrillation.
Most people would be terrified. Jansen was mad.
"I wasn't scared. I knew exactly what it was," he says now. "I was pissed.
"I thought my season was over. I'm like, man, f--- this. Not again. We're trying to go back to the World Series. I have a chance to win another Trevor Hoffman award. Man!"
Jansen, now back on the active roster after being away from the team due to the irregular heartbeat on Aug. 9 in Denver, announced Wednesday that he would not travel with the Dodgers to Colorado this weekend, following doctor's orders.
"I tried everything to get it back into rhythm for 15, 20 minutes. And then I'm finally like, all right, let's just call 911.

Jansen said that while doctors told him its not safe to travel back to Colorado this weekend, there's a chance he would be cleared to pitch there if the Dodgers face the Rockies in the playoffs.
He's going to have an MRI this week, and the 3-D images doctors take of his heart will help them understand exactly what and where the underlying issue is. It's possible a different dosage of the heart medication he was on could allow him to pitch safely again, without as many side effects.
It's also possible Jansen sits out any games the Dodgers play in Colorado until he can have the second ablation surgery in the offseason.
"I talk to my doctor all the time," he said. "He told me to call any time of the day or night. He's ready. He told me to just focus on the positive, on all the things that have gone right with this, and not the fact I have to go through it again or worrying about what could happen. Just stay positive."
