尖端扭转型室性心动过速(torsade de pointes,TdP)是一种与QT间期或校正的QT间期(corrected QT interval,QTc)延长相关的多形性室性心动过速,可引起可逆性晕厥,也可恶化为心室颤动,导致心脏性猝死(sudden cardiac death,SCD)。一些已上市...
结果QTc, JTc,QT/TQ延长者,VT,VF及/或心性猝死的发生率明显大于QTc,JTc,QT/TQ值正常者(P<0.05,<0. 01);VT,VF及/或心性猝死QTd,JTd,QTcd明显大于无VT... 戚厚兴,杨志寅,韩继冉 - 《济宁医学院学报》 被引量: 0发表: 2001年 Use of ECG Restitution (Beat-to-Beat QT-TQ Interval Analysis) to...
Results:Heart rate (P= .073), QT interval (P= .432) and QTc interval (P= .179) were similar before and after thyroid surgery. Tp-e interval (84.6 ± 13.1 vs 77.2 ± 10.9; P= .031), Tp-e/QT ratio (0.23 ± 0.04 vs 0.21 ± 0.04; P< .001), Tp-e/QTc ratio (0.21± 0.04 ...
ICH E14: A New Regulatory Guidance on the Clinical Evaluation of QT/QTc Internal Prolongation and Proarrhythmic Potential for Non-antiarrhythmic Drugs Many experts consider prolongation of the QT/ QTc interval on an electrocardiogram to be a potential clinical biomarker for serious or even life-threa...
尖端扭转型室性心动过速(torsade de pointes,TdP)是一种与QT间期或校正的QT间期(corrected QT interval,QTc)延长相关的多形性室性心动过速,可引起可逆性晕厥,也可恶化为心室颤动,导致心脏性猝死(sudden cardiac death,SCD)。一些已上市的药物,如特非那定、阿司咪唑、格雷沙星和西沙必利等,被发现有较高的诱发QT...

We compared heart rate-corrected QT interval (QTc) and its within- and between-subject variability, in ECGs recorded several days apart for 207 patients with schizophrenia (age range 19-60 yr) with age- and gender-matched healthy controls. Patients had higher heart rates (mean±s.d.) than ...
How to measure the QT interval--what is normal? The QT interval extends from the beginning of the QRS complex to the end of the T wave. Since the report of Jervell and Lange-Nielsen in 1957, it has been difficult to determine whether to measure a QT or a QU interval. U waves are ...
Corrected \{QT\} (QTc) interval was the strongest clinical predictor of appropriate \{ICD\} therapy (458 ± 30 ms vs. 430 ± 35 ms; p = 0.001). Multivariate logistic regression analysis demonstrated a 1.2-fold increased likelihood of appropriate therapy per 10-ms increase in QTc, ...
