Using microtransducers, the intracardiac phonocardiogram was recorded in 8 horses from the right heart and in 6 of them also on the left side. All 4 heart sounds were recorded but not in all sites. Their timing was related to pressure events. Systolic ejection murmurs were recorded in both the pulmonary artery and the aorta. Diastolic murmurs were recorded in 2 horses with aortic regurgitation, with maximum amplitude in the left ventricle. The findings were similar to those reported in man and agree with some of the recent concepts on heart sound production.
使用微型换能器，对8匹马的右心进行了心内心音图记录，其中6匹马还记录了左心的心内心音图。记录到了所有4个心音，但并非在所有部位都能记录到。它们的时间与压力事件相关。在肺动脉和主动脉中均记录到了收缩期喷射性杂音。在2例主动脉瓣关闭不全的马中记录到了舒张期杂音，最大振幅出现在左心室。这些发现与人类报道的结果相似，并且与一些关于心音产生的最新概念相符。
