Recognizing the above characteristics will guide us to perform rightatrialactivation and entrainment mapping on purpose, and then identify rapidly the typical atrial flutter.
认识上述特点，有助于引导我们有目的地进行右房激动标测和拖带标测，从而可以快速识别出典型房扑。
2
Objective To observe effects of rightatrial appendage (RAA) pacing and atrial septal (AS) pacing on atrial activation.
目的观察右心耳及房间隔起搏对心房电活动的影响。

It is known that the macro-reentry activation in the right atrium is the mechanism of atrial flutter.
