Interestingly, the 720-day mortality was similar in patients with prolonged and normal QTc (44% vs 42%, p = 0.546), but was significantly higher in patients with prolonged QRS interval than in those with normal QRS (59% vs 37%, p = 0.004). In Cox proportional hazards analysis...
目的探讨QRS时限,Tp-Tec,QTc在慢性心力衰竭(CHF)患者心电图检查中的应用价值.方法选取2016年8月至2018年1月我院收治的60例CHF患者为研究对象,根据是否合并室性心律失常将其分为A组(24例,合并室性心律失常)和B组(36例,未合并室性心律失常),另选取同期入院体检的健康人员30名作为C组.所选对象均在入院后接受心...
本文结果显示心肌梗死患者VLP阳性组较阴性组的QTcd显著增大(P<0.01),VLP阳性组发生心脏事件(心力衰竭、室颤、死亡)人数显著高于VLP阴性组(P<0.05),相关分析QTcd与FQRS和LAS40呈正相关、与RMS40呈负相关,提示QTcd与VLP指标有良好的相关性。另外发生心脏事件中除室颤、死亡增多外,心力衰竭患者VLP阳性率较高,表明...
奥布替尼片的适应症是健康受试者 此药物由北京诺诚健华医药科技有限公司生产并提出实验申请,[实验的目的] 评价奥布替尼在临床有效血浆浓度下对QTcF间期的影响,对于健康受试者心电图参数的影响及PK特征,以及奥布替尼在健康受试者中的安全性和耐受性。
For patients with intraventricular conduction delays (bundle branch block, paced rhythms), a modified QTc was calculated using the formula: (QT—(QRS—120msec)) /√RR [12]. All the EKGs done during the hospital stay were studied. The data were analyzed using Statistical Package for the ...
