NPPB and Paroxysmal atrial fibrillation: In a dual-chamber pacemaker case–control study with continuous device surveillance, NT-proBNP was higher in patients with recent AHRE ≥ 6 min and paroxysmal AF than in pacemaker controls without AHRE, with an NT-proBNP threshold > 150 pg/mL conferring a markedly increased odds of AHRE [67].
