Key result
The arithmetic average of beat-by-beat heart rate values overestimates true mean heart rate, with a smaller error in heart failure patients than healthy controls.
Why the study?
Does the arithmetic average of beat-by-beat sampled heart rate values overestimate true mean heart rate compared to true heart rate calculation?
Observational (n=32)
No

The arithmetic average of beat-by-beat sampled heart rate values overestimates true heart rate, highlighting the need for correct calculation approaches in clinical data analysis.
The arithmetic average of beat-by-beat sampled heart rate (HR) values overestimates true HR defined as number of heart beats per time unit. The aims of this study were to (1) estimate the magnitude of overestimation; (2) illustrate the significance of this issue using data from patients with congestive heart failure (CHF) and control subjects; and (3) outline approaches to correctly calculate mean HR.

Harald M. Stauss (2011) conducted an observational in Congestive Heart Failure (n=32). Congestive heart failure vs. Healthy controls was evaluated on Error in mean heart rate calculation (arithmetic average minus true mean HR in bpm) (p=<0.05). The arithmetic average of beat-by-beat heart rate values overestimates true mean heart rate, with a smaller error in heart failure patients than healthy controls.
