ECG features of AVRT with antidromic conduction: Procainamide (class I) would be our first line antiarrhythmic. Ibutilide (class III) and amiodarone are second-line options, but their …

AVNRT and AVRT Arrhythmias caused by a surplus conduction circuit between atrial and ventricular anatomy. They cause the normal electrical circuit to allow an impulse to repeatedly …

ECG features of Atrioventricular Nodal Reentrant Tachycardia (AVNRT). There are three types of AVNRT and the difference between them lies in the configuration of the re-entry circuit. …

Nov 18, 2022 · What is AVNRT? Atrioventricular Nodal Reentrant Tachycardia is a type of supraventricular tachycardia (ie it originates above the level of the Bundle of His) and is the …

This article discusses pre-excitation, AVRT and Wolff-Parkinson-White WPW (syndrome), with emphasis on ECG and clinical features, and management.

Aug 24, 2010 · When a wide-QRS tachycardia is encountered and ventricular tachycardia is excluded, the possible diagnoses are AVNRT or atrial tachycardia with aberrant conduction …

Jan 14, 2020 · Current maneuvers for differentiation of atrioventricular node reentry tachycardia (AVNRT) and atrioventricular reentry tachycardia (AVRT) lack sensitivity and specificity for …

Aug 7, 2023 · The diagnosis of AVNRT requires visualization of an electrocardiogram (ECG). In most cases, an ECG will show heart rate between 140 and 280 beats per minute (bpm), and in …

Most cases are typical with a short RP interval, so it is important to recognize associated electrocardiographic (ECG) features, conduction patterns, and how it is distinguished from …

Atrioventricular nodal reentrant tachycardia (AVNRT) should be classified as typical or atypical. The term ‘fast-slow AVNRT’ is rather misleading. Retrograde atrial activation during …
