Three ablation strategies using very high-power short-duration catheter in paroxysmal atrial fibrillation: The Q-INDEX randomized trial.
BACKGROUND Very high-power short-duration (vHPSD; 90 W/4 sec) ablation shortens pulmonary vein isolation (PVI) but produces shallower lesions that may be inadequate in the thick anterior left atrium. OBJECTIVE To compare vHPSD, ablation index (AI)-guided, and hybrid strategies for PVI in paroxysmal atrial fibrillatio...
