持久型房性心动过速比较少见,Scheinman提到1974年前的文献中只有20例,此后,国内外文献偶见散在报道;至于持久型房性心动过速伴有传出阻滞,即阻滞部位不在房室结而在异位起搏点的周围,则更为罕见,我们最近遇到一例病史达11年之久的持久型房性心动过速伴传出阻滞,静脉注射阿托品及经食道心房调搏超速抑制能暂时恢复窦性心律,报道如下。 Long-lasting atrial tachycardia is relatively rare, Scheinman mentioned in the literature prior to 1974, only 20 cases, since then, scattered reports of domestic and foreign literature occasionally; for persistent atrial tachycardia accompanied by the block, that is, resistance Hysteresis is not in the atrioventricular node and around the ectopic pacemaker, is even more rare, we recently encountered a case history of 11 years of persistent atrial tachycardia with block, intravenous injection of atropine and Esophageal atrial pacing speeding can temporarily restore sinus rhythm, reported as follows.
