conclusions right ventricular pacing increases the qt interval without increasing the jt interval. our results confirm that jtc, as an index of repolarization, is independent of ventricular depolarization. therefore, it can be applied for predicting qtc in patients with lbbb. results stimulation from the rva increased the qtc from 456.20 ± 38.63 ms to 530.67 ± 47.73 ms at a cl of 600 (p < 0.000...

background: incidence and predominant subtype  of guillain-barre syndrome (gbs) differs geographically. electrophysiology has an important  role in early diagnosis and  prediction  of prognosis. this study  is conducted to determine the frequent  subtype  of gbs in a large group of patients  in iran and compare  nerve conduction studies in axonal and demyelinating forms of gbs. methods:    we  ...

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: 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...

Auckland City Hospital provides electrophysiology (EP) procedures for people residing in the Northern Region and is a national service paediatric congenital cardiac patients. Electrophysiology are primarily therapeutic typically undertaken with view to ablation. When ablation not delivered, these considered diagnostic. This retrospective study was explore clinical characteristics outcomes of pa...
