Key result
Low HRV on a 2-minute rhythm strip linked to higher CHD and mortality risk.
Why the study?
Does low heart rate variability in a 2-minute rhythm strip predict risk of coronary heart disease and mortality?
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.
May flag higher CHD/mortality risk on routine short ECGs; leaves open added value beyond standard predictors.
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.
