Atrial fibrillation (AF) is the most common cardiac arrhythmia. Pharmacologic and non-
pharmacologic rhythm control strategies impact on AF-related symptoms, while leaving …

Background Local theory and the vectorial theory are used to explain the origin of P-wave
dispersion (PWD). There are no previous studies that analyze both at the same time …

For years, there has been an increase in cases of atrial fibrillation, reaching alarming levels.
This is why intense work is done to find predictors of this arrhythmia. The electrocardiogram …

Abstract Background/Aim: In atrial fibrillation (AF) ablation procedures, it is desirable to know
whether a proper disconnection of the pulmonary veins (PVs) was achieved. We …

Atrial fibrillation (AF) is the most common arrhythmia. It is associated with increased stroke
risks, thromboembolism, and other complications, which are great life and economic …

Objective: This study aimed to evaluate the acute effect of cryoballoon ablation (CB-A) on
electrocardiographic parameters that have been suggested to reflect heterogeneity in atrial …

En 1998 se describió un nuevo parámetro electrocardiográfico, denominado dispersión de
la onda P (Pd). Se utiliza, principalmente, como predictor eléctrico de la fibrilación auricular …

ABSTRACT P-wave dispersion (PWD) has been used for more than two decades for the pre-
diction of atrial fibrillation, but its mechanism of production in the electrocardio-gram is not …

Desde hace más de dos décadas se utiliza la dispersión de la onda P (Pd) para la
predicción de fibrilación auricular, pero no hay certeza de su mecanismo de producción en …

Pulmonary vein isolation is nowadays the cornerstone for the treatment of paroxysmal atrial
fibrillation (AF). However, its success rate is not as high as clinically desirable, and repeated …
