  • 简介:心力衰竭是一种致残性慢性疾病,它是老年人致病和致死的一个主要原因。心衰病人有着不同的致病因素,但是慢性交感神经和β-肾上腺素受体(β-AR)的激活是心衰发生时共有的现象。慢性交感神经和β-AR的激活对心脏是有害的,在心衰恶化、心脏功能异常和心肌重构进展中发挥重要的作用。交感-儿茶酚胺系统通过直接激动

  • 简介:目的探讨病理性室性期前收缩(PVS)的特征及临床意义。方法将336例常规心电图有PVS者分为正常组(A组)和心脏病组(B组)进行12导联同步心电图检测,并按有关标准进行分析。结果Lown分级法和Schamroth分类法对判断病理性PVS与功能性PVS有重要的参考价值。结论宽大畸形伴明显切迹、多源与多形性、成对出现、起源于左心室者以及伴继发性ST-T改变的PVS绝大多数见于病理性

  • 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:[摘要]目的探讨奥施康定联合加巴喷丁治疗神经病理性疼痛疗效。方法晚期肿瘤的神经病理性疼痛患者,通过视觉类比量表(VAS)和主诉分级进行疼痛强度评估,分为A组奥施康定组40例,B组奥施康定+加巴喷丁组40例,通过个体化用药,研究其治疗疼痛缓解度,有效率和显效率。结果A组疼痛完全缓解9例,明显缓解17例,其有效率85%,显效率65%,B超疼痛完全缓解12例,明显缓解19例,有效率92.5%,显效率77.5%,结论奥施康定+加巴喷丁治疗神经病理性疼痛疗效显著。

  • 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。
