摘要
目的:观察缓释二氢奎尼丁血药浓度与QTc间期、QT间期离散度、QUc间期等参数的相关性。方法:40例心房颤动病人口服缓释二氢奎尼丁。心电图记录采用50mm/s纸速,2倍电压的方法。血药浓度测定采用TDX方法。结果:①缓释二氢奎尼丁疗效明显,转复窦性心律54.6%(6/11例),预防心房颤动复发有效率71.4%(25/35例)。②血药浓度与QUc间期高度相关(r=0.93,P<0.01)。③服药前、后心肌复极离散度比较无差异。用药后U波发生率明显增加,但未见药物的致心律失常作用。结论:缓释二氢奎尼丁血药浓度与QUc间期高度相关。
? Objective:To study the correlation between the serum concentration of dihydroquinidine SR and QT,QTc dispersion or QUc. Methods:Forty patients with atrial fibrillation taken dihydroquinidine SR were observed.ECG with 50 mm/s paper speed and 2 times voltage was recorded.The serum concentration of dihydroquinidine was determined by the method of TDX. Results:①The dihydroquinidine SR was effective in the treatment of atrial fibrillation with 546%(6 of 11 cases) reversion of sinus rhythm and 714%(25 of 35 cases) with no recurrence of atrial fibrillation.②There was a high correlation between drug concentration and QUc(r=0.93,p<0.01).③No difference occurred in myocardial repolarization dispersion before and after the treatment,and no druginduced arrhythmia either. Conclusion:Dihydroquinidine SR is an effective drug in the treatment of atrial fibrillation and there is a high correlation between its serum concentration and QUc interval.
