Manchester United manager Sir Alex Ferguson received treatment on Thursday for a minor heart irregularity.

It can cause the heart to beat between 140 and 240 beats a minute, compared with a normal resting rate of 70.
Sir Alex has a demanding schedule and has recently been involved in a legal battle over his ownership of the champion racehorse Rock of Gibraltar.
