Risk stratification after acute myocardial infarction by amplitude–frequency mapping of cyclic variation of heart rate

Abstract Background Blunted cyclic variation of heart rate (CVHR), measured as a decrease in CVHR amplitude (Acv), predicts mortality risk after acute myocardial infarction (AMI). However, Acv also can be reduced in mild sleep apnea with mild O2 desaturation. We investigated whether Acv's predi...
