Abstract

In this study we evaluated the validity of well-known human electrocardiographic markers of myocardial pathology in Dorper sheep. These markers include: the duration of the QRS complex of premature ventricular complexes (PVCs), the presence of notching of the QRS complex of PVCs and change of the ST-segment of PVCs. It was shown that these three electrocardiographic phenomena correlate with myocardial pathology in the hearts of Dorper sheep. We also describe a new electrocardiographic indicator of myocardial pathology, namely an increase in the frequency of cardiac memory T waves as a new electrocardiographic surrogate for myocardial pathology in the hearts of Dorper sheep.

摘要

在本研究中，我们评估了多珀羊中心肌病变的知名人类心电图标志物的有效性。这些标志物包括：室性早搏（PVC）的QRS波群时限、PVC的QRS波群切迹的存在以及PVC的ST段改变。结果表明，这三种心电图现象与多珀羊心脏的心肌病变相关。我们还描述了一种心肌病变的新心电图指标，即心脏记忆T波频率增加，作为多珀羊心脏中心肌病变的一种新的心电图替代指标。
