British racing is fitting horses with heart monitors in a trial to find out why some thoroughbreds collapse and die during races.
The first three horses were fitted with a “wearable” heart monitor in an under-the-saddle pad as the new equipment was trialled at Ascot last week.
Exercise Associated Sudden Death (EASD) in racehorses is a rare occurrence. It affects 0.04 per cent of starters, of which 0.02 are believed to be heart related. It is often hard for pathologists to prove in a post-mortem, and is an assumption in the absence of any other signs.
