2024年10月8日 · ECG features of AVNRT. P waves if visible exhibit retrograde conduction with P-wave inversion in leads II, III, aVF. They may be buried within, visible after, or very rarely visible before the QRS complex. Associated features include:

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. Virtually all cases of AVNRT are characterized by having one fast and one slow pathway.

2022年11月18日 · Atrioventricular Nodal Reentrant Tachycardia (AVNRT) is a type of SVT and is the commonest cause of palpitations in patients with hearts exhibiting no structurally abnormality.

AV nodal reentry tachycardia can be diagnosed by your physician via an electrocardiogram or an Ambulatory monitoring device, i.e. Holter or Event monitor, specifically during an arrhythmia episode. These episodes of SVT can be intermittent and not reliably present on a daily

2023年8月7日 · Atrioventricular nodal reentrant tachycardia (AVNRT) is a type of paroxysmal supraventricular tachycardia that results due to the presence of a reentry circuit within or adjacent to the AV node. The diagnosis of AVNRT requires visualization on an electrocardiogram (ECG).

2025年3月17日 · Reentrant atrioventricular nodal tachycardia (AVNRT), it is the most frequent supraventricular paroxysmal tachycardia in healthy hearts, and may represent 60% of them 1. It is more frequent in women and in intermediate ages especially between 40-50 years.

2010年8月24日 · Typically, AVNRT is a narrow-complex tachycardia, ie, QRS duration <120 ms, unless aberrant conduction, which is usually of the right bundle-branch type, or a previous conduction defect exists. Tachycardia-related ST depression …

2025年1月5日 · In practice, junctional tachycardia will frequently be misdiagnosed as AVNRT or AVRT (given the greater frequency of these diagnoses). Junctional tachycardia is suggested by more rate variability over time.

ECG features: Orthodromic: Narrow complex tachycardia 200-300bpm; P waves hidden in QRS complexes or retrograde Inverted inferior and Lead I P waves indicate left sided pathway; T wave inversion; ST depression; Antidromic: Wide complex tachycardia 200-300bpm
