Resumen
ASENSIO-LAFUENTE, Enrique et al. Deductive analysis of the electrocardiogram to determine the site of origin of premature ventricular beats/contractions. Cardiovasc. metab. sci [online]. 2021, vol.32, n.4, pp.214-225. Epub 05-Abr-2024. ISSN 2954-3835. https://doi.org/10.35366/102773.
Premature ventricular contractions (PVC’s) have become a therapeutic target, especially when the arrhythmia burden is higher than 10% of the recorded beats. Knowing their point of origin can help to optimize the different treatment strategies, especially the invasive ones. Deductive electrocardiogram (ECG) analysis is a rational methodology that assesses the activation vector and morphologies of the PVC’s thus allowing a quite precise definition of the arrhythmia originating focus. Knowledge of the different cardiac structures within the chest and the heart itself as well as between them facilitates the comprehension of the vectors and morphologies on the twelve-lead ECG and gives valuable information to complete the patient’s clinical picture. Here we present the main ways to analyze the PVC’s ECG from the classical concepts, and we include diagnostic parameters to identify their point of origin.
