摘要
根据室性早搏向量图QRS环初始向量、最大向量空间方位分布.对100例频发单源室性早博向量图进行定位。分析结果:冠心病、病毒性心肌炎、高血压性心脏病及其它室性早搏原因待查的发病率分别占51%、25%、8%、14%。室性早搏向量图QRS环最大向量位于左后下方的最多,占52%;初始向量位于左前下方的最多.占68%.并提出了左、右心室前、后壁及间隔部心内膜早搏向量图初始向量和最大向量分布的空间范围。
The localization of frequent mono--focus VPB in 100 cases with vectorcardiogram has been anal-ysed. According to the relation between the disease and the initial--vector in QRS loop in VPB vector-cardiogram,and the distribution of the maximum vectors in the space images,the proportions of coro-nary heart disease, viral myocarditis, hypertensive heart disease,and other VPB are 51%, 25%, 8%and 14% respectively.The maximum--vectors in QPS loop in the VPB vectorcadiogram are mostly atthe left posterior lower part, amounting to 52%, while the initial--vectors are mostly at the left anteri-or lower part,amounting to 68%. The distribution of the initial--vectors and the maximum--vectorsin the space images in the vectorcardiogram which shows the premature beats on the endocardium ofthe septum and the anterior and the posterior wall of the left and the right ventricles is presented.
