Four-time Major champion Rory McIlroy has revealed that a recent health check has shown up an 'irregularity' with his heart.
McIlroy is confident that the situation is under control and says it is more than likely attributable to a viral infection that he picked up in 2016.
McIlroy is counting down to his 2018 season starting on Thursday in Abu Dhabi and he doesn't envisage this news setting him back, so long as he maintains the levels of fitness that he has come to be known for.

"I've got a bit of an irregularity with my heart that I have to keep on top of," he told The Telegraph.
"I have a flat T-wave and I'll have to get an echo [cardiogram] on my heart every six months and an MRI scan every year.
"I suffered a really bad viral infection in China 18 months ago and they told me that's the reason that I have this thickening of my left ventricle and there's a bit of scar tissue.
"For now, I just need to stay on top of it and have to stay fit. Hey, I was planning on doing that anyway."
McIlroy was hampered throughout last season by injury and he failed to pick up a victory on Tour during 2017, his first trophy-less calendar year since 2013.
A troublesome rib injury that never got the time to heal was one of the main factors but he is now confident that a four-month layoff has him fresh and ready to roll for a new season.
"The rib's fine, no problems whatsoever – I had an MRI scan on my thoracic spine and all was okay," he said.
McIlroy is 10.00 to win the Masters in April and complete his career Grand Slam of the Majors, while he can be backed at 3.75 to win at least one of golf's four marquee events in 2018.
