Racing: Heart threat to Waterloo

WATERLOO BOY, one of the best two-mile chasers, will continue his career despite a disorder of the heart which may have been responsible for his poor run behind Travado at Exeter on Tuesday. The 10-year-old was pulled up then and David Nicholson, his trainer, said yesterday that the gelding is suffering from a fibrillating heart. This twitching of the wall of the heart interferes with the organ's normal rhythmical contractions. 'It basically means that the heart is out of synch,' the trainer said. 'Sometimes it goes back of its own accord. Another of my horses, Tug Of Gold, suffered from it.'
