Response to Letter Regarding Article, “Dominant Frequency of Atrial Fibrillation Correlates Poorly With Atrial Fibrillation Cycle Length”

Letter by Berenfeld and Jalife regarding article "dominant frequency of atrial fibrillation correlates poorly with atrial fibrillation cycle length".

BACKGROUND Localized sites of high frequency during atrial fibrillation (AF) are used as target sites to eliminate AF. Spectral analysis is used experimentally to determine these sites. The purpose of this study was to compare dominant frequencies (DF) with AF cycle length (AFCL) of unipolar and bipolar recordings. METHODS AND RESULTS Left and right atrial endocardial electrograms were record...

Increased IL-17A in Atrial Fibrillation Correlates with Neutrophil to Lymphocyte Ratio

Background: Atrial Fibrillation (AF) is the most common cardiac arrhythmia and an independent risk factor for stroke among the elderly. A role for inflammation in the atrial remodeling as well as development and recurrence of AF is known. Objective: To compare IL-17A between patients with different types of AF and healthy individuals. Methods: IL-17A was measured in sera of 112 patients and 107...

Letter by Haft regarding article, "High prevalence of atrial fibrillation among patients with ischemic stroke".

BACKGROUND AND PURPOSE Atrial fibrillation (AF) is a common cause of devastating but potentially preventable stroke. Estimates of the prevalence of AF among patients with stroke vary considerably because of difficulties in detection of intermittent, silent AF. Better recognition of AF in this patient group may help to identify and offer protection to individuals at risk. Our aim was to determin...

Response to Letter Regarding Article, "Ablation of Persistent Atrial Fibrillation Targeting Low-Voltage Areas With Selective Activation Characteristics".

Response to Letter Regarding Article, “Ablation of Persistent Atrial Fibrillation Targeting Low-Voltage Areas With Selective Activation Characteristics” We thank Bartoletti et al for their comments on our novel approach for ablation of persistent atrial fibrillation (AF) targeting selective atrial low-voltage sites. Here we provide answers to their comments: 1. Left atrial substrate characteriz...
