Auricular dissociation is a rare and interesting arrhythmia, characterized by ectopic auricular thythm, independent of the basic one. The basic and accessory auricular rhythm never interfere in between, the latter always being restricted to a smaller part of auricle and is almost never conducted to ventricles. It is most frequently a slow rhythm, and is rarely recorded as auricular fibrillation and undulation of one auricle, or as auricular tachycardia. Almost always the auricular dissociation develops in critical states and most frequently appears several hours prior to a lethal end. A typical case of auricular dissociation is described in a male subject with active myocardial infarction that originated several hours prior to the lethal end of the patient. In our case a rare variant of auricular dissociation is concerned, combined with AV dissociation.
心房分离是一种罕见且有趣的心律失常，其特征为异位心房节律，独立于基本节律。基本心房节律和附加心房节律从不相互干扰，后者总是局限于心房的较小部分，几乎从不传导至心室。它最常见的是缓慢节律，很少记录为心房颤动和单个心房的波动，或心房性心动过速。心房分离几乎总是在危急状态下发生，最常在致命结局前数小时出现。本文描述了一名患有急性心肌梗死男性患者的典型心房分离病例，该心肌梗死在患者致命结局前数小时发生。在我们的病例中涉及一种罕见的心房分离变异型，合并房室分离。
