心室前向电力增大,近年来国内外均甚重视,因为这涉及左室内传导系统,即中隔支传导阻滞的问题和与一些常见的心电向量现象,例如:右室肥厚、右束支传导阻滞、A型预激综合征、正后壁心肌梗塞、正常变异等的诊断和鉴别诊断问题。中隔支传导阻滞的诊断标准,国内外多采用Nakaya等于1978年提出的,这标准是用统计学方法求得的,是人为的,称“任意标准”(arbitrary criterion),与实际情况是否完全相符,还须从各个方面加以检验。关于中隔支阻滞的本质、名称和诊断均有不少争论,其心电向量图的确切图形也无详细描述。研究心室内传导阻滞的本质和制订其诊断标准,观察阻滞前后的心电向量改变是一种较好的方法。Rosenbaum等树立左束支多分支传导阻滞的概念,就是通过这种观察而得出的。Piccolo等对心室前向传导阻滞的观察,通过右房调搏形成前向电力增大,对比其前后的变化,而提出新的观点。
Ventricular anterior power increases in recent years both at home and abroad are very important, because it involves the left ventricular conduction system, the septal branch block problems and with some common ECG vector phenomena, such as: right ventricular hypertrophy, right bundle Branch block, A-WPW syndrome, posterior wall myocardial infarction, normal mutation and other diagnosis and differential diagnosis. Diagnostic criteria for septal branch block, both at home and abroad using Nakaya equal to the proposed in 1978, this standard is statistically calculated, is artificial, called “arbitrary criterion” (arbitrary criterion) Fully consistent, but also from all aspects to be tested. About the nature of block in the septum, name and diagnosis are many controversies, the exact shape of the ECG vector graph is not described in detail. It is a good method to study the essence of ventricular conduction block and formulate its diagnostic criteria to observe changes of ECG vector before and after block. Rosenbaum such as the establishment of left bundle branch block branch concept, is through this observation derived. Piccolo and other observations of the anterior ventricular conduction block, the formation of forward power through the right atrial pacing increases, compared to its changes before and after, and put forward new ideas.
