Low exercise HR at moderate workload may flag higher AF risk in men; extends risk models but remains hypothesis-generating without prospective validation.
Does low exercise heart rate predict incident atrial fibrillation in healthy middle-aged men?
Low exercise heart rate at a moderate workload is a long-term predictor of incident atrial fibrillation in healthy middle-aged men, with the risk substantially amplified by elevated baseline blood pressure.
Grundvold et al. (2013) studied this question.
