阵发性房性心动过速(PAT)少见。异位起搏点可在窦房结及其周围区域和左右心房的其他部位形成。但PAT发生的确切机理还不完全清楚。Dimarco等认为三磷酸腺苷(ATP)对某些类型的室上性心动过速和室性心动过速是一种有效的治疗药物。关于ATP终止阵发性或持续性房性心动过速文献中已有3组病例报告。本文报告ATP对PAT的疗效的研究结果。
Paroxysmal atrial tachycardia (PAT) rare. Ectopic pacemaker can be formed in the sinus node and its surrounding area and other parts of the left and right atrium. However, the exact mechanism by which PAT occurs is not fully understood. Dimarco so that adenosine triphosphate (ATP) for some types of supraventricular tachycardia and ventricular tachycardia is an effective treatment. There are three reported cases of ATP termination of paroxysmal or persistent atrial tachycardia. This article reports the results of ATP on the efficacy of PAT.
