The authors performed a model loading of the right heart ventricle in 40 dogs in 17 dogs--acute tension loading by creating a partial ligature (banding) of the pulmonary artery; the dogs were examined in respect to the changes hemodynamics and ECG for a period of three hours. In the second group of 10 dogs a chronic tension loading of the right heart was created by a partial ligation of the pulmonary artery (banding); the dogs were followed--up in respect to hemodynamic and vectocardiographic changes for a period of one year. In the other group of 10 dogs a chronic loading of the right heart: was formed by operative route and interatrial defect was obtained; the dogs were followed-up in respect to hemodynamics and vectrocardiographic changes for a period of one year. The authors described the changes in the intraventricular conduction of vectro cardiograms, made by the three plane system of Akulincev, and these vectrocardiograms were compared with the type and degree of loading as well as with the morphologic changes occurred in the heart. The authors indicated the nonspecificity of TBB as a sign of volume loading of the right heart ventricle.
作者对40只犬的右心室进行模型加载，其中17只犬通过对肺动脉进行部分结扎（束带术）造成急性张力负荷；对这些犬进行了为期三小时的血流动力学和心电图变化检查。在第二组10只犬中，通过肺动脉部分结扎（束带术）造成右心慢性张力负荷；对这些犬进行了为期一年的血流动力学和心电向量图变化随访。在另一组10只犬中，通过手术途径造成右心慢性负荷并形成房间隔缺损；对这些犬进行了为期一年的血流动力学和心电向量图变化随访。作者描述了由阿库林采夫三平面系统得出的心电向量图心室传导变化，并将这些心电向量图与负荷类型和程度以及心脏发生的形态学变化进行了比较。作者指出TBB作为右心室容量负荷征象的非特异性。
