Fully automatic procedures allow a dramatic reduction of analysis time but the level of accuracy loss is unknown. In this study we compared automatic and interactive measurements of HRV indexes in a sample of 246 Holter recordings from chronic heart failure patients. We measured the total power of HRV and the power in the very low (0.01-0.04 Hz), low (0.04-0.15 Hz) and high (0.15-0.4 Hz) frequency bands. The comparison between the two methods was performed by computing the normalized difference between automatic and interactive measurements and estimating the bias and 95% limits of agreement. Automatic measurements showed a small bias (&amp;lt; &amp;plusmn;8%) compared to interactive measurements, while the limits of agreement were &amp;le;&amp;plusmn;23% in all spectral indexes. Our results indicate that the systematic and random difference between automatic and interactive measurements of spectral indexes of HRV are acceptable for clinical studies.<\/jats:p>","DOI":"10.3233\/978-1-61499-101-4-128","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T17:07:49Z","timestamp":1740157669000},"source":"Crossref","is-referenced-by-count":0,"title":["Automated Versus Interactive Spectral Analysis of Heart Rate Variability from 24-Hour Holter Recordings in Heart Failure Patients"],"prefix":"10.3233","author":[{"family":"Maestri Roberto","sequence":"additional","affiliation":[]},{"family":"La Rovere Maria Teresa","sequence":"additional","affiliation":[]},{"family":"Pinna Gian Domenico","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Quality of Life through Quality of Information"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T17:17:50Z","timestamp":1740158270000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=180&spage=128"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-101-4-128","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2012]]}}}
