目前国内有较多文献将不完全性房内阻滞命名为不完全性左房、右房阻滞[1-5]。我们认为这一命名并不妥当,值得商榷。一般认为[2,3],不完全性右房内阻滞表现为P波高尖,类似于肺型P波,与结间束(尤其是后结间束)阻滞有关;不完全性左房内阻滞表现为P波增宽,类似于二尖瓣型P波,与上房间束阻滞有关。结间束位于右房内,而上房间束起源于前结间束,亦有一部分位于右房内。不难看出,将不完全性房内阻滞分别命名为不完全性左房内阻滞或不完全性右房内阻滞,是由
At present, there are many literature will be incomplete incomplete atrial block named incomplete left atrial, right atrial block [1-5]. We think this name is not proper and it is open to question. Is generally believed that [2,3], incomplete right atrial block showed high P-wave tip, similar to pulmonary P wave, and the intercostal bundle (especially after the bundle) block; incomplete left atrial Internal block showed P-wave broadening, similar to mitral-type P wave, and the beam on the room block. The intercostal bundle is located in the right atrium, while the upper intercostal bundle originates in the anterior intercostal bundle, and some in the right atrium. It is not difficult to see that incomplete intra-atrial block were named as incomplete left atrial block or incomplete right atrial block is caused by
