Standard, augmented limb leads and three orthogonal leads (I, aVF and V(10)) taken simultaneously were recorded from 25 rabbits. Records were analyzed for rate, rhythm, interval duration and component amplitudes. The wave forms of QRS complexes were analyzed in all leads. P, QRS, and T vectors were calculated for the mean frontal (dorsal), sagittal, and transverse planes. Study of orthogonal leads in sternal recumbency indicated that ventricular activation is spatially oriented sinistrad or dextrad, ventrad and caudad.
从25只兔子身上同时记录标准肢体导联、加压肢体导联和三个正交导联(I、aVF和V(10))。对记录进行心率、心律、间期时长和各波段振幅分析。分析所有导联中QRS复合波的波形。计算额面(背面)、矢状面和横面的平均P、QRS和T向量。对胸骨卧位时正交导联的研究表明,心室激动在空间上呈向左或向右、向前和向后的方向。
