The aim of this study was to compare short-term heart rate variability (ST-HRV) parameters from 60-min electrocardiograms in dogs with sick sinus syndrome (SSS, n=20) or chronic mitral valve disease (CMVD, n=20) and healthy controls (n=50), and to verify the clinical application of ST-HRV analysis. The study groups differed significantly in terms of both time - and frequency- domain ST-HRV parameters. In the case of dogs with SSS and healthy controls, particularly evident differences pertained to HRV parameters linked directly to the variability of R-R intervals. Lower values of standard deviation of all R-R intervals (SDNN), standard deviation of the averaged R-R intervals for all 5-min segments (SDANN), mean of the standard deviations of all R-R intervals for all 5-min segments (SDNNI) and percentage of successive R-R intervals &gt;50 ms (pNN50) corresponded to a decrease in parasympathetic regulation of heart rate in dogs with CMVD. These findings imply that ST-HRV may be useful for the identification of dogs with SSS and for detection of dysautonomia in animals with CMVD.<\/jats:p>","DOI":"10.1515\/pjvs-2017-0021","type":"journal-article","created":{"date-parts":[[2017,5,19]],"date-time":"2017-05-19T10:02:20Z","timestamp":1495188140000},"page":"167-172","source":"Crossref","is-referenced-by-count":13,"title":["Short-term heart rate variability in dogs with sick sinus syndrome or chronic mitral valve disease as compared to healthy controls"],"prefix":"10.1515","volume":"20","author":[{"given":"Sz.","family":"Bogucki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Noszczyk-Nowak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref21","first-page":"25237","article-title":"Autonomic dysfunction predicts poor physical improvement after cardiac rehabilitation in patients with heart failure","author":"Compostella","year":"2014","journal-title":"Res Cardiovasc Med"},{"key":"ref201","first-page":"2015","article-title":"Short -
