文摘

PurposeAdenosine infusion during atrial fibrillation ablation is often used to evaluate for dormant pulmonary vein (PV) conduction. Several physiologic effects of adenosine may be seen during infusion, including atrioventricular (AV) block, hypotension, sinus tachycardia (as a reflex mechanism), and sinus bradycardia. However, hypotension and sinus tachycardia may be seen in the absence of AV block. Whether the dose required to achieve AV block versus any physiologic effect (e.g., hypotension) is relevant when evaluating for PV reconnection is unclear.
