Effects of beta-blockade with bisoprolol on heart rate variability in advanced heart failure: analysis of scatterplots of R-R intervals at selected heart rates.

abstract：:Fifty adult men with mild to moderate hypertension were recruited to participate in a double-blind crossover study. Each subject received 14 days of drug treatment and 14 days of placebo treatment (random order). Half the subjects were assigned to a metoprolol (150 mg/day) vs placebo treatment regimen and half to an a...
