Journal ArticleDOI
Preoperative electrocardiographic risk assessment of atrial fibrillation after coronary artery bypass grafting.
TL;DR: The role of surface ECG in assessment of risk of new‐onset atrial fibrillation (AF) after coronary artery bypass grafting surgery (CABG) is evaluated.
Journal ArticleDOI
Correction for QT/RR hysteresis in the assessment of drug-induced QTc changes--cardiac safety of gadobutrol.
TL;DR: The so‐called thorough QT/QTc (TQT) studies required for every new pharmaceutical compound are negative if upper single‐sided 95% confidence interval of placebo and baseline corrected QTc prolongation is <10 ms.
Journal ArticleDOI
Prognostic value of blood pressure measured during hospitalization after acute myocardial infarction: an insight from survival trials.
Yee Guan Yap,Trinh Duong,J Martin Bland,Marek Malik,Christian Torp-Pederson,Lars Køber,Stuart J. Connolly,Mark M Gallagher,A. John Camm +8 more
TL;DR: In post-MI patients with left ventricular ejection fraction less than 40% or asymptomatic ventricular arrhythmia, reduced blood pressure measured during hospitalization after MI significantly predicts all-cause mortality and arrhythmmic mortality, and can be reliably used to identify patients who are at risk of dying after MI.
Journal ArticleDOI
Practical use of T wave morphology assessment.
Markus Zabel,Marek Malik +1 more
TL;DR: The latter study in US veterans therefore was the first to demonstrate that a novel parameter characterizing heterogeneity of ventricular repolarization within the 12-lead surface ECG permits risk stratification in patients with cardiovascular disease.
Journal ArticleDOI
Performance of basic ventricular tachycardia detection algorithms in implantable cardioverter defibrillators: implications for device programming.
M. H. Anderson,Francis Murgatroyd,Katerina Hnatkova,B. Xie,Suzanne Jones,Edward Rowland,David E. Ward,A. J. Camm,Marek Malik +8 more
TL;DR: It is concluded that ventricular tachycardia is detected with the highest specificity if all beats in an analyzed sequence are required to be “fast” even after lengthening of the tachycardsia detection interval to maintain sensitivity.
