Using a catheter with 2 transducers, one mounted at the tip and one 9 cm proximal to it, enabled transvalval pressure waveforms to be recorded in 8 horses. A simultaneous electrocardiogram acted as a time base. The changing waveforms produced in the chambers of the heart and great vessels are described and related to the events of the cardiac cycle. The effect of second degree AV block, ectopic beats, a pan diastolic murmur and chronic obstructive pulmonary disease are described.
使用带有两个换能器的导管,一个安装在尖端,另一个在其近端9厘米处,从而能够记录8匹马的跨瓣膜压力波形。同步心电图作为时间基准。描述了心脏腔室和大血管中产生的变化波形,并将其与心动周期事件相关联。还描述了二度房室传导阻滞、异位搏动、全舒张期杂音和慢性阻塞性肺疾病的影响。
