Journal ArticleDOI
Characterization of QT interval adaptation to RR interval changes and its use as a risk-stratifier of arrhythmic mortality in amiodarone-treated survivors of acute myocardial infarction
TL;DR: A new method is proposed to evaluate the dynamics of QT interval adaptation in response to heart rate (HR) changes, discriminating between post-myocardial infarction patients at high and low risk of arrhythmic death while on treatment with amiodarone.
Proceedings ArticleDOI
Optimal lead configuration in the detection and subtraction of QRS and T wave templates in atrial fibrillation
Johan E.P. Waktare,Katerina Hnatkova,Carl Meurling,H. Nagayoshi,T. Janota,A. J. Camm,M. Malik +6 more
TL;DR: An in-house written software package was used to generate templates of QRS complexes and T waves using self-similarity techniques, and leave a residual signal representing only atrial activity as mentioned in this paper.
Proceedings ArticleDOI
A computer package generating non-invasive atrial electrograms: detection and subtraction of QRS and T waves
Katerina Hnatkova,Johan E.P. Waktare,Carl Meurling,H. Nagayoshi,T. Janota,A. J. Camm,M. Malik +6 more
TL;DR: A software package which uses self-similarity techniques to allow the subtraction of ventricular signals during atrial fibrillation (AF) is described.
Proceedings ArticleDOI
Time for QT adaptation to RR changes and relation to arrhythmic mortality reduction in amiodarone-treated patients
TL;DR: A measure of the optimum fit residuum (ORR) is calculated, showing a remarkable discriminative power to identify post-myocardial infarction patients at high risk of arrhythmic death after treatment with amiodarone.
Proceedings ArticleDOI
Reproducibility of T-wave morphology assessment in patients with hypertrophic cardiomyopathy and in healthy subjects
TL;DR: Computerized measurements of T-wave morphology are highly reproducible and may provide a reliable assessment of repolarization abnormalities in patients with hypertrophic cardiomyopathy and healthy subjects.
