简介:目的分析并探讨基于心血管疾病临床用药的合理性。方法对2012年6月-2013年6月入院诊治的92例心血管疾病患者的临床用药资料进行回顾性分析,分析并总结其用药处方,调查患者的疾病分类、用药剂量及用药时间,以药物利用指数(DUI)为指标判断心血管疾病临床用药的合理性。结果92例心血管疾病患者以冠心病为主,DDDs位于前三位的药物依次为硝苯地平、异山梨酯和尼群地平;除非洛地平和硝酸异山梨酯外,其他药物的DUI值均≤1。结论我院在心血管疾病治疗临床用药方面基本合理,遵循依据患者具体病情给药、合理配比用药的原则,为心血管疾病患者尤其是老年患者提供科学的、有针对性的用药方案甚至进行个体化治疗,才能避免发生不良反应并有效提高治愈率。
简介:目的分析从体表心电图(ECGT)测量QT离散度(QTd)的错误理由。方法使用立体心电图仪对确诊的心肌梗死患者和正常对照组各100例,进行24导通道实时同步描记12导联ECG,普通心电向量图(VCG),3导正交心电图(O-ECG),9导时间心向量图(T-VCG),变向时间心向量图(DCT-VCG)检测。结果(1)病例和对照组的QT间期,QTc在体表ECG,O-ECG,T-VCG三者之间的相关性良好(r=0.879-0.993,P<0.01),而QTd,QTcd在体表ECG和T-VCG之间无明显相关;(2)两组所测QTd,QTcd值在体表ECG和O-ECT,体表ECG和T-VCG间均有显著性差异(P<0.01),而QT,QTc无明显差异;(3)从两组间的比较来看:病例组较对照组QT,QTc间期均在体表ECG,O-ECGtT-VCG上有明显延长,而QTd,QTcd仅在体表ECG上两组间的差异有显著性(P<0.01),而在O-ECT,T-VCG上两组间无显著性差异。结论同步12导联的体表ECG,在同一心动周期中只有1个整体的QT间期。QT间期的测量最好采用SECG,因从T-VCG的角度观察更准确。虽体表ECG上测量QTd在不同组间有差异,但在T-VCG上并无显著性差异。
