Journal ArticleDOI
Evolution of changes in the ventricular rhythm during paroxysmal atrial fibrillation
Mark M Gallagher,Katerina Hnatkova,Francis Murgatroyd,Johan E.P. Waktare,Xiaohua Guo,A. J. Camm,Marek Malik +6 more
TL;DR: Changes in the RR interval within episodes of paroxysmal atrial fibrillation (PAF) have not been fully characterized, and during paroxYSms of AF, the mean RR interval and the variability of RR intervals increases.
Journal ArticleDOI
Does the prulifloxacin ECG study prove cardiac safety of the drug
TL;DR: The regulatory requirements for a meaningful conduct of the thorough QT/QTc studies have repeatedly been discussed, including the most recent publication summarizing some of the problems encountered in design and review of the studies, and the most important problem with the prulifloxacin study is that it used only the therapeutic dose.
Journal ArticleDOI
Improved identification of late potentials by adjustment of the number of analyzed segments of the spectral temporal mapping of the signal-averaged electrocardiogram
TL;DR: Spectral temporal mapping (STM) of the SAECG is a new frequency domain technique that uses fast Fourier transform analysis and it is crucial for correct analysis to avoid the presence of high frequency components in the last 5 reference segments.
Journal ArticleDOI
The effect of age on the electrophysiological and autonomic correlates of sudden death after acute myocardial infarction.
O Odemuyiwa,Thomas Farrell,Marek Malik,Yaver Bashir,Jan Poloniecki,David E. Ward,A. John Camm +6 more
TL;DR: Sudden death is a more predominant mode of death and is more strongly associated with lower heart rate variability and with the VE10 incidence in young than in older postinfarction patients, and age should be taken into account when assessing the risk of sudden death.
