Implication
May warrant slow pathway ablation in select tachycardia-induced cardiomyopathy cases; hypothesis-generating for dual AV nodal conduction as reversible mechanism.
Structured PICO
P
Population
2 patients referred for evaluation of symptomatic, incessant, and irregular narrow-complex tachycardia, misdiagnosed as atrial fibrillation, for consideration of pulmonary vein isolation.
I
Intervention
Slow atrioventricular (AV) nodal pathway ablation
O
Outcome
Cure of tachycardias and recovery of ventricular function
Simultaneous conduction over dual AV nodal pathways can mimic atrial fibrillation and cause tachycardia-induced cardiomyopathy, which is curable with slow pathway ablation.
