Kara M, Cetin EHO, Korkmaz A, Ozeke O, Cay S, Ozcan F, Aras D, Topaloglu S. Transient changes in QRS morphology during a narrow complex tachycardia: What is the mechanism? J Cardiovasc Electrophysiol 2022; 33:1320-1321. [PMID: 35524413 DOI: 10.1111/jce.15523] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 04/24/2022] [Accepted: 05/01/2022] [Indexed: 11/28/2022]
Abstract
The observation of electrograms and electrocardiograms recorded in sinus rhythm can offer important initial information about the mechanism of arrhythmia. Some patients may have both bundle branch aberrancy or a bystander pathway or multiple pathways, giving rise to varying degrees of QRS fusion. There is need to focus on any change in cycle length of the tachycardia and morphology of QRS during tachycardia. This article is protected by copyright. All rights reserved.
