PHOENIX -- Dodgers closer Kenley Jansen said he's significantly improved from his diagnosis of an irregular heartbeat and could return to action next Tuesday night when the club opens a three-game series at Washington.
"I've just been trying to stay in shape and stay sharp. I'm feeling great," Jansen said prior to Wednesday night's game against the D-backs at Chase Field. "Those days that I missed I don't feel like I've got to get back into it. I feel ready. I could go out and pitch today if they needed me. But I can't. I've got to get off the blood thinner first. That's how good I feel."
Jansen hasn't pitch since Aug. 27 when he felt his heart accelerate and experienced a loss of breath and dizziness. He was diagnosed with atrial fibrillation, a malady that affects more than 50 percent of the U.S. population. The condition contains a slight higher risk of blood clots in the chamber of the heart, which is the reason Jansen was placed on a blood thinner.
Two days after he comes off the thinner he'll be eligible to pitch. Club physicians are concerned that Jansen would be subjected to excessive bleeding if he receives a wound while pitching. That could be dangerous.
"They're concerned that if a ball came back at me it could hit me," he said.
Jansen is scheduled to stop taking the medication on Friday. Because the club is traveling on Monday he should be cleared to return the next day. He'll undergo a procedure during the offseason to try to shock his heart back into regular rhythm.
"It's not a big deal," he said. "I just have to get it done so I don't have to worry about it in the future."
Jansen is 5-3 with a 2.54 ERA and 25 saves in 56 appearances.
