This review looks back at important and clinically relevant new developments in the fields of invasive electrophysiology and device therapy in 2014. Many findings do not only apply to pure electrophysiologists, but also to every clinical cardiologist’s practice. The authors have extracted the key findings of studies with potential guideline impact and put those into a clinical perspective. Look...

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  ...

The term "Electrophysiological remodeling" defines the changes of atrial electrophysiologic properties taking place in atrial myocites during atrial fibrillation and/or following periods of sustained atrial fibrillation (AF). Early research was prompted by clinical observations: many patients were seen to get through increasingly frequent and longer paroxisms of AF to persistent AF, until chron...

Ablation of peristent AF remains challenging with questions unanswered about what the ideal next step after pulmonary venous isolation should be. Ibutilide is a highly effective class III agent for cardioversion of acute-onset atrial flutter and fibrillation, with limited clinical use due to risks of ventricular pro-arrhythmias. However, results from the on-going MAGIC-AF trial may re-invigorat...

Background Acute Inferior ST Elevation Myocardial Infarction (Ac-Inf-STEMI) and associated posterior and right ventricular (RV) infarction has been extensively studied with electrophysiology and echocardiography. A recent CMR study showed that poor RV function was associated with poor long term survival post myocardial infarction. However, limited CMR data exists especially on short term clinic...

CHF and AF are common problems that are frequently encountered together. These two disease states interact in a way that can result in a viscous cycle. This brief review will attempt to address the interaction between AF and CHF, atrial pathology and abnormal electrophysiology, clinical consequences, prognostic importance, and therapy.

A number of revolutionary techniques and technologies have been introduced to the clinical electrophysiology laboratory in recent years which have offered new insights into arrhythmia mechanisms and as a result are enhancing strategies for ablating cardiac arrhythmias. They are aimed at improving the resolution, three-dimensional spatial localization, and/or rapidity of acquisition of cardiac a...
