Does low heart rate variability in a 2-minute rhythm strip predict risk of coronary heart disease and mortality?
Low heart rate variability measured from a short 2-minute rhythm strip may serve as a marker for increased risk of coronary heart disease and mortality.
Low HRV was associated with increased risk of CHD and death from several causes. It is hypothesized that low HRV is a marker of less favorable health.
Dekker et al. (2000) studied this question.
