异位——传出阻滞是指起搏在窦房结以外的异位节律点,并伴有向周围组织传出阻滞(即传导障碍)。可分为异位—心房传出阻滞,前向性或逆向性结区(房室交界区)传出阻滞及异位——心室传出阻滞三种基本类型。这类心电图变化及其临床意义越来越被人们重视,故在此加以介绍。 Ectopic - outblocking refers to pacing ectopic rhythm point outside the sinoatrial node, accompanied by the outgoing block to the surrounding tissue (ie, conduction disorders). Can be divided into ectopic - atrial block, forward or reverse junction (atrioventricular junctional area) block and ectopic - ventricular block three basic types of block. This type of ECG changes and its clinical significance of more and more attention, it is introduced here.
