A minor heart condition has been developed by Harry Judd from pop band McFly and this has happened after he took training for the London marathon to be held this month.

According to Harry, he has an ectopic heart beat. In this condition, the heart beats too fast or there are beats missed by the heart but this is nothing to worry about.

He says it is because he has been doing excessive exercise but has told fans it is nothing to worry about.

Harry said on Twitter, "It's known as a Wandering Pacemaker commonly seen in athletes.... it's really annoying!!! It's nothing to worry about but just means I have to chill out a bit."

According to the British Heart Foundation, ectopic heart beat is when the heart skips a beat or beats a little faster but this condition is harmless.

Harry is running the 26.2 miles London marathon with a group of friends on 21st April to raise money for charity.

Harry has been exercising before also but this time he took it more seriously.

He was given the sad news recently and this has affected him.
