flecainide has been known to cause torsades de pointes (tdp) in patients with structural heart disease and its mechanism has been attributed to use-dependency. we present a patient with flecainide-induced tdp in the absence of any other precipitating factors.this case highlights potential reverse use dependence associated with flecainide resulting in tdp.

Introduction: Today electrophysiology studies and ablation have been developed due to increasing arrhythmias disorder of heart. In these diagnostic – treatments methods, the use of fluoroscopy can be causes patient radiation dose, therefore evaluation of patient's absorbed dose is necessary to protection of the radiation. The aim of this study was to evaluate the absorbed dose in patients under...

introduction: more and more patients have been undergoing electrophysiological study (eps) as the number of rhythmologists have increased. due to the increased interest in the study, today eps applications are made even in second step public hospitals or private hospitals. our aim is to compare two electrophysiology labs, that are in different regions with social and economic development, in te...

IN THE CONTEXT of history scientists often share the fate of artists, for the final judgment of their work is subject to the whims of later generations. Even a great scientist may fade into obscurity as later investigators incorporate his ideas into their own and forget their origin. Such a fate seems to have befallen John Scott Burdon-Sanderson. Working in the last two decades of the nineteent...

Noninvasive imaging of cardiac electrophysiology is still a major goal despite all recent technical innovations. This review gives an overview about the historical background, recent developments and possible future applications of noninvasive imaging of cardiac electrophysiology.

This work proposes an optimal control approach for the termination of re-entry waves in cardiac electrophysiology. The control enters as an extracellular current density into the bidomain equations which are well established model equations in the literature to describe the electrical behavior of the cardiac tissue. The optimal control formulation is inspired, in part, by the dynamical systems ...

• Although voltage clamp methods have been applied experimentally to cardiac tissue for over a decade, this field of study has failed to achieve general acceptance because of limitations of the experimental approach and difficulty in interpreting the results. Yet this technique is valuable within its limitations, and to dismiss it would be to lose a valuable tool. In perspective, most technique...
