【摘要】 目的 探讨血管紧张素Ⅱ受体拮抗剂(ARB)对器质性心脏病合并阵发性心房颤动(AF)P波离散度(Pd)、最大P波时限(Pmax)及AF发生率的影响。方法 79例器质性心脏病合并AF患者,随机分成试验组40例;对照组39例。试验组给予缬沙坦干预,观察缬沙坦对P波离散度(Pd)、最大P波时限(Pmax)及AF发生率的影响。结果 试验组3个月后Pd、Pmax明显减小,AF的发生率较对照组亦明显降低。结论 缬沙坦可减小Pd、Pmax,同时可部分预防AF的发生。

[Abstract] Objective To investigate the influence of angiotensin Ⅱ receptor blockade on P dispersion(Pd),maximal time of P waves(Pmax) and recurrence rate of atrial fibrillation(AF).Methods Seventy-nine patients,who had organic heart diseases combined with AF,were divided into two groups at random:the experiment group included 40 patients; the contrast group included 39 patients.The patients from experiment group toke valsartan,and observed the influence of valsartan on Pd,Pmax and recurrence of AF.Results After 3 months the Pd and Pmax decreased,and the recurrence rate of AF obviously decreased compared with the contrast group too.Conclusion Valsartan can dicrease Pd and Pmax,and at the same time can prevent the recurrence of AF.

随着心房颤动(AF)成为心脏电生理研究领域的一个热点,近期对其发生的预测指标亦进行了较多探讨。有报道AF患者的P波最大时限(Pmax)和P波离散度(Pd)较窦性心律者增大[1]。血管紧张素转换酶抑制剂(ACEI)能够减轻心房电重构,减少复律后AF的发生,但血管紧张素Ⅱ(ATⅡ)受体拮抗剂(ARB)对Pd和Pmax是否有影响目前尚缺乏研究。本研究初步观察了缬沙坦(怡方)对器质性心脏病合并阵发性AF患者Pd、Pmax及AF发生率的影响,现报告如下。
