窦房传导阻滞是一种传出阻滞,由于窦房结发出的激动在窦房连接组织内发生传导障碍而使激动不能下传。此时常会发生交界性或室性逸搏,偶见房性逸搏。窦房传导阻滞伴交界性或室性逸搏后如随之以一次窦性下传的心搏,即组成逸搏-夺获,如果连续出现几组,则成为逸搏-夺获二联律。交界性逸搏-夺获二联律较为常见,房性逸搏-夺获二联律殊为少见。现将近期发现的一例 The sinoatrial block is an outgrowth that can not be transmitted because of the conduction disturbance that occurs in the sinoatrial node connected tissue. At this time often occurs at the junction or ventricular Yat stroke, occasionally anecdotal. The sinoatrial block with borderline or ventricular aneurysm, followed by a sinus heartbeat, that is composed of escape - to win, if there are several consecutive groups, then escape - won the couple law. Junction of escapement - won the couplet law is more common, atrial escape - won the couplet law is rare. An example recently found
