Incidence, Predictive Factors, and Prognostic Significance of Supraventricular Tachyarrhythmias in Congestive Heart Failure

BACKGROUND: The incidence, predictive factors, morbidity, and mortality associated with the development of supraventricular tachyarrhythmias (SVTs) in patients with congestive heart failure (CHF) are poorly defined.
