Abstract Funding Acknowledgements Type of funding sources: None. Introduction Radiofrequency (RF) catheter ablation the slow pathway (SP) in atrioventricular nodal reentry tachycardia (AVNRT) is highly effective; however, it may require prolonged fluoroscopy and RF time. Procedural outcomes improve by using electroanatomical mapping systems (EAM), and/or intracardiac echocardiography (ICE). Pur...

Abstract Background Understandings of subtypes atypical atrioventricular nodal reentrant tachycardia (AVNRT) using variants slow pathway (SP) are still growing. Inferolateral (inf-lat-) left atrial (LA) SP is a rare variant extending into an inf-lat-LA along the mitral annulus (MA). Purpose To characterize unknown subtype fast-slow (F/S-) AVNRT inf-lat-LA-SP as retrograde limb (inf-lat-LA-F/S-A...

Congenitally corrected transposition of great vessels (CCTGV) is a rare congenital heart disease (CHD) accounting for <1% of CHDs. CCTGV with infundibular pulmonary stenosis (PS) with ventricular septal defect (VSD) is part of Fallot's physiology. It is known to be associated with bradyarrhythmias like atrioventricular (AV) blocks, and acquired complete AV block occurs at a rate of 2% per year....

BACKGROUND Atrioventricular nodal reentry tachycardia (AVNRT) represents the most commonly encountered type of regular paroxysmal supraventricular tachycardia. This study determined whether administration of adenosine-5'-triphosphate (ATP) during sinus rhythm may be useful in the noninvasive diagnosis of dual AV nodal pathways. METHODS AND RESULTS During electrophysiological study, we intrave...

OBJECTIVES The purpose of this study was to examine whether P wave signal-averaged electrocardiogram (P-SAECG), which detects subtle changes in P wave, detects the concealed accessory atrioventricular pathway (AP). BACKGROUND It is difficult to differentiate atrioventricular reciprocating tachycardia (AVRT) due to the AP from atrioventricular nodal reentrant tachycardia (AVNRT) when the ventr...

The aim of this prospective, non-randomized interventional study was to assess electrophysiological effects, efficacy and safety of intravenous propafenone in termination of atrioventricular nodal reentrant tachycardia (AVNRT) and orthodromic atrioventricular reentrant tachycardia (AVRT). This single-center study was carried out at Department of Cardiology, Sestre milosrdnice University Hospita...

Historically, slow pathway (SP) ablations were considered an anatomically focused procedure. Presently, novel mapping techniques have been used to identify targets for Atrioventricular Nodal Tachycardia (AVNRT). There various anatomical descriptors along the perinodal region. Described in literature, preferential myocardial bundles are arranged from sinoatrial node (SAN) with inputs into atriov...

BACKGROUND Immunohistochemistry studies suggest that the anatomic substrate of the slow pathway in atrioventricular nodal reentrant tachycardia (AVNRT) is the left inferior nodal extension. We hypothesized that slow pathway ablation from the left septum is an effective alternative to right-sided ablation. METHODS AND RESULTS We analyzed our databases of AVNRT in search of cases that had used ...

To establish an appropriate treatment strategy and determine if ablation is indicated for patients with narrow QRS complex supraventricular tachycardia (SVT), analysis of a standard 12-lead electrocardiogram (ECG) is required, which can differentiate between the 2 most common mechanisms underlying SVT: atrioventricular nodal reentry tachycardia (AVNRT) and orthodromic atrioventricular reentry t...
