US number one Mardy Fish is eyeing a return to tennis competition at Wimbledon after a procedure to address a frightening heart arrhythmia, USA Today reported.
"It felt like my heart was going to jump out of my chest," Fish told the newspaper in a telephone interview.
It was the first time Fish had spoken about the condition that had kept him off the ATP Tour, and which prompted to withdraw from the French Open, the second Grand Slam of the year now underway at Roland Garros.
Fish told the newspaper he had a procedure called cardiac catheter ablation in Los Angeles on Wednesday to correct faulty wiring in his heart.
"It has been so scary," Fish said, explaining the condition caused him to wake in the night with heart palpitations.
"It was super-hard to go to sleep," he said.
Fish said doctors believe the procedure "was very successful, and that it's totally behind me now."
He said he expects to resume light training and return in time for Wimbledon or perhaps the pre-Wimbledon grass court tournament at London's Queens Club.
"Look, I'm still in the top 10 in the world and still the No. 1 American," Fish said. "This is still a very fun time for me. I don't want to sit on my ass while I'm 10 in the world."
