Electroanatomical mapping for visualization of atrial activation in patients with incisional atrial tachycardias.
AIMS Incisional atrial tachycardias in patients following surgery for congenital heart disease are based on complex structural abnormalities in these hearts. The aim of this study was to evaluate the use of the electroanatomical mapping system, CARTO, in consecutive patients with different forms of incisional atrial tachycardia. METHODS AND RESULTS The electroanatomical mapping system combine...
متن کاملApplication of ripple mapping with an electroanatomic mapping system for diagnosis of atrial tachycardias.
BACKGROUND Three-dimensional (3D) mapping is often used to guide ablation in atrial tachycardia (AT), but maps can be susceptible to annotation and interpolation errors. Ripple Mapping (RM) is a technique that displays electrogram time-voltage data simultaneously as dynamic bars on the surface shell to overcome these limitations. OBJECTIVES We hypothesized that RM would be superior to establi...
متن کاملMultiple atrial tachycardias after atrial fibrillation ablation: the importance of careful mapping and observation.
A combination of pulmonary vein isolation (PV), electrogram-based ablation, and linear lesions have been demonstrated to result in medium-term freedom from atrial fibrillation (AF) in the majority of patients with persistent AF in several studies. Such an extensive ablation is associated with a high incidence of postablation atrial tachycardia (AT), which is often complex and multiple. Deductiv...
متن کاملIatrogenic Left Atrial Tachycardias
epending on initial ablative approach, the incidence of left trial tachycardia (LAT) or flutter after atrial fibrillation AF) ablation has varied about 10-fold. Using segmental, stial pulmonary vein (PV) and/or antral isolation, about 3% f patients require repeat ablation for LAT (1,2). Conersely, using widely encircling PV lines plus mitral and roof ines, LAT incidence is often 20% to 30% (3,4...

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...
