Andy Murray has demanded that regular heart screenings be made compulsory in tennis following the cardiac arrest suffered by Bolton Wanderers midfielder Fabrice Muamba at White Hart Lane on Saturday.
Muamba's heart had stopped for 78 minutes before he was able to be resuscitated. The 23-year-old had a comfortable night in intensive care last night although he remains in a critical condition.
Murray, who has his heart checked independently on a regular basis, told MSN Sport: "With all the pressure and stress of modern sport you have no idea how much you are pushing yourself on the pitch or court, I think it's something that's just got to be done.
"I've been doing my tests for three years now so I have heart scans, heart monitors and other tests.
"But it's not something that's done within tennis. But I just think it should be. Everyone should have a medical or a check-up before you're allowed to compete because it's such a horrible thing for people to witness."
Murray is currently preparing to compete in the Miami Masters, where he will face Alejandro Falla later this week.
