Self-reported heart rate measurements at rest highly correlated with office ECG (r=0.68) and 24-hour Holter recordings (r=0.67), but showed poor agreement under exercise conditions.

Are self-reported heart rate measurements reliable compared to office ECG and 24-h Holter recordings in patients with heart disease?
Self-reported heart rate measurements by patients at rest are reliable and adequately represent circadian variation, but are not accurate under exercise conditions where 24-h Holter or stress ECG is necessary.
Effect estimate: r=0.68
The purpose of this study was to evaluate the measurement of heart rate undertaken in clinical studies by (1) assessing the repeatability and reproducibility of heart rate measurements by various methods and under various conditions and (2) determining whether a single heart rate measurement at rest is representative of the circadian and inter-day variation of heart rate. Prospective cohort study in 102 patients with various types of heart disease at Duisburg Heart Center, Germany between 2011 and 2012. The heart rate measurements were based on self-assessment, ECG tracings at rest, and bicycle stress ECG in the office as well as 24-h Holter ECG. Office measurements and self-assessment at rest as well as 24-h Holter ECG and self-assessment at rest are highly correlated, but no correlation between self-assessment and office recordings/24 h recordings under exercise conditions was seen. Coefficient of variability was below 10 % for the self-assessment and for office measurements at rest. There were no differences in coefficient of variability during the day and within the 6 days for self-assessment of heart rate at rest and circadian variation was normal. At rest heart rate measurements by various methods agree sufficiently and inter-day/circadian variation is adequately represented. Under exercise conditions self-assessment of heart rate is not valuable and use of 24 h Holter as well as stress ECG recordings is necessary. Thus, self-reported heart rate measurements by the patient at rest seem to be reliable, but should be used in clinical studies only for heart rate assessment at rest.
Albanese et al. (Mon,) conducted a cohort in Heart disease (n=102). Self-assessment of heart rate vs. Office ECG, 24-h Holter ECG, and stress ECG was evaluated on Correlation and agreement between self-assessed heart rate and clinical recordings at rest and under exercise (r=0.68). Self-reported heart rate measurements at rest highly correlated with office ECG (r=0.68) and 24-hour Holter recordings (r=0.67), but showed poor agreement under exercise conditions.
