Reference ranges for ambulatory heart rate measurements in a middle-aged population
Authors' conclusion
Ambulatory HR varies widely in healthy middle-aged individuals, a finding with relevance for the management of patients with a perception of tachycardia. Differences in ambulatory HR between individuals are largely independent of common clinical correlates.
