Auscultation was used to examine 545 horses for cardiac murmurs and some arrhythmias. The most significant finding was the high prevalence of right-sided holosystolic or pansystolic plateau-type murmurs compatible with a diagnosis of tricuspid regurgitation in National Hunt racing Thoroughbreds of all ages (16.4%). This condition was found in 4.7% of flat-racing Thoroughbreds, 3.7% of non-racing Thoroughbreds and Thoroughbred crosses, and in none of the ponies examined. High prevalences of left-sided early systolic murmurs (53%), left-sided early diastolic murmurs (23%), right-sided early diastolic murmurs (22%) and second degree atrioventricular block (23%) were found in racehorses of both types.
通过听诊对545匹马进行心脏杂音和一些心律失常的检查。最显著的发现是，在各年龄段的国家狩猎赛马纯种马中，与三尖瓣反流诊断相符的右侧全收缩期或全收缩期平台型杂音的患病率很高（16.4%）。在平地赛马纯种马中，这一情况的发生率为4.7%，在非赛马纯种马和纯种杂交马中为3.7%，在所检查的矮种马中未发现。在两种类型的赛马中均发现左侧收缩期早期杂音（53%）、左侧舒张期早期杂音（23%）、右侧舒张期早期杂音（22%）和二度房室传导阻滞（23%）的高患病率。
