BACKGROUND:

Clinical experience suggests that atrial tachyarrhythmias (ATs) are a frequent comorbidity in heart failure patients with left ventricular systolic dysfunction and that volume overload may increase AT susceptibility. However, substantiating this apparent relationship in free-living patients is difficult. Recently, certain implantable cardioverter-defibrillators provide, by measuring transpulmonary electric bioimpedance, an index of intrathoracic fluid status (OptiVol index [OI]). The goal of this study was to determine whether periods of greater intrathoracic fluid congestion (as detected by OI) correspond with increased AT event frequency.

METHODS AND RESULTS:

This analysis retrospectively assessed the relation between AT events and OI estimate of volume …

Atrial fibrillation (AF) is associated with an increased risk of mortality as well as significant morbidity including bothersome symptoms, exacerbation of heart failure, and thromboembolic events. Explanations for the mortality risk are variable, but the majority opinion favors AF as a marker of reduced health status, especially cardiovascular health.
