Objective To investigate the effect of different signal length during electrocardiography (ECG) on results of heart rate (HR)-corrected heart rate variability (HRV) analysis and explore the minimum time window of signal collection for accurate HRV analysis. Methods 24-hour electrocardiogram signal were collected from 116 normal controls and 72 hypertrophic cardiomyopathy (HCM) patients admitted in the First Affiliated Hospital of Army Medical University during May 2017 to November 2019. Nine commonly used HRV metrics in clinical practice were obtained by HR-corrected HRV analysis. The HRV results of 24-hour signal length served as reference standards, and then the accuracy and reliability of HRV results at a signal length of 5, 30 and 60 min were compared, respectively. Results In results of HR-corrected HRV analysis at 3 different signal lengths, all the 9 HRV metrics were significantly lower in the HCM patients than the normal controls (P |
