Characterization of Sustained Atrial Tachycardia in Dogs with Rapid Ventricular Pacing‐Induced Heart Failure

Abstract

CHF promotes inducibility of sustained atrial tachycardia. Based on the mode of tachycardia induction, responses to pacing and calcium antagonists, and presence of DADs, atrial tachycardia in this CHF model has a mechanism most consistent with DAD-induced triggered activity resulting from intracellular calcium overload.
