读贵刊92年2期后,对以下几处持有异议,今提出愿与同仁共同商榷。 1、73页下《室性早搏折返径路中的逆文克白现象》一文中附图,我认为是交界性早搏,而不是“室性早搏”。其理由有二:早搏形态似基本的窦性QRS,初始向量相同,皆为CRBBB型,仅S波略宽和略深于基本的QRS,这是其一;其二是早搏随联律间期逐渐变小而终末向量(S波)亦逐渐加宽加深。本例窦性下传的QRS为CRBBB型,若早搏激动源于左束支,其形态虽亦为CRBBB型,但源于受损的右束支阻滞平面以下的室早实为多见。
After reading your period two years in 1992, I hold objections to the following places. Now I propose to discuss with my colleagues. 1,73 page “ventricular premature beats off the path of the inverse white grams,” a picture, I think it is borderline premature beats, not “premature ventricular contractions.” There are two reasons for this: premature beat morphology is similar to basic sinus QRS, the initial vector is the same, all CRBBB type, only S wave slightly wider and slightly deeper than the basic QRS, which is one; the second is premature beat with the inter-law interval Gradually smaller and the terminal vector (S wave) also gradually widened and deepened. In this case, sinus QRS CRBBB type, if the premature beat originated from the left bundle branch, although the shape is also CRBBB type, but from the damaged right bundle branch block below the room early morning is more common.
