Novel algorithmic methods in mapping of atrial and ventricular tachycardia.

Arrhythmias in Patients With Pulmonary Hypertension; A Narrative Review of the Current Literature

Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

CARTO three-dimensional non-fluoroscopic electroanatomic mapping for catheter ablation of arrhythmias: a useful tool or an expensive toy for the electrophysiologist?

This review enlightens the application issues of the novel CARTO electroanatomic mapping system (Biosense Webster, Diamond Bar, CA, USA) in both research and clinical electrophysiology. It is a very useful tool in catheter ablation procedures in patients with sustained atrial tachycardias, macroreentrant atrial arrhythmias after surgical correction of congenital heart disease, and ventricular t...

Clinical and Electrocardiographic comparison of patients with primary Mitral Valve Prolapse Syndrome and control group

ABSTRACT: Mitral Valve Prolapse (WVP) in one of the commonest cardiac abnormalities. Echocardiography has generally been accepted as the diagnostic modality of choice, To assess the characteristic symptoms signs and electrocardiographic abnormalities of MVP results of prospective 500 age and sex matched healthy subjects without echocardiographic MVP (control subjects). The diagnostic criteria...

  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...

Confirmation of novel noninvasive high-density electrocardiographic mapping with electrophysiology study: implications for therapy.

BACKGROUND Twelve lead ECGs have limited value in precisely identifying atrial and ventricular activation during arrhythmias, including accessory atrioventricular conduction activation. The aim of this study was to report a single center's clinical experience validating a novel, noninvasive, whole heart, beat-by-beat, 3-dimensional mapping technology with invasive electrophysiological studies, ...
