QTd is a useful surrogate marker for adverse functional prognosis, which might help to stratify risk in patients with acute IS. Keywords: acute ischemic stroke, functional outcome, QT dispersion, …

QT dispersion (QTd) has been proposed as an indirect ECG measure of heterogeneity of ventricular repolarization. The predictive value of QTd in acute stroke remains controversial. …

2000年11月15日 · Many clinical studies have measured QT dispersion only in the six precordial leads. In addition, other lead combinations, such as the orthogonal XYZ or “quasiorthogonal” I, …

2016年2月12日 · 摘要:目的: 观察冠状动脉旁路移植术 (CABG)对QT离散度 (QTd)的影响,探讨其临床价值。 方法: 选取39例行CABG成功的患者作为实验组,测量分析其术前7d、术后1~7d以 …

2000年1月4日 · To test the independence of QTc and QTD as predictors of mortality, multivariate Cox models were used, including age, sex, body mass index (BMI), diabetes, diastolic and …

QT 离散度(QT dispersion, QTd) ,指体表12 导联心电图各导联间QT 间期存在的差异程度,反映心室肌复极的不均一性, 代表心室肌兴奋恢复时间不一致程度[8],这一现象早为人所发现,但未被重 …

2021年1月21日 · Several studies have confirmed the association between acute cerebrovascular events and QTd (8 – 12). In patients admitted to hospital for acute cerebrovascular diseases, …

1998年12月15日 · This study examines the relation of QT dispersion (QTd) on a surface electrocardiogram (ECG) to clinical features and established risk factors of sudden cardiac …

Measuring QT dispersion (QTd) is a fairly straightforward and noninvasive technique for predicting mortality in patients at high risk following a myocardial infarction (MI).

QT dispersion (QTd) is equal to longer QTc minus shorter QTc measured by 12-lead electrocardiogram (ECG). QTd reflects inhomogeneity in repolarization of ventricular …
