Depression of HRV has been observed in many clinical scenarios, including autonomic neuropathy, heart transplantation, congestive heart failure, myocardial infarction (MI), and other cardiac and noncardiac diseases. However, it is important to realize that clinical implication of HRV analysis has been clearly recognized in only two clinical conditions: (1) as a predictor of risk of arrhythmic events or sudden cardiac death after acute MI, and (2) as a clinical marker of evolving diabetic neuropathy. Recently, its role in evaluation and management of heart failure has also been recognized. It is pertinent to recognize the limitations of HRV as far as its clinical utility at present is concerned. The methodology of HRV had remained poorly standardized until the recent publication of the Special Report of the Task Force of ESC\/NASPE, and thus has been presenting difficulty in comparing earlier existing data. Also, determination of the exact sensitivity, specificity, and predictive value of HRV, as well as the normal values of standard measures in the general population, still require further investigation before better standards can be set for existing and future clinical applications. This article reviews the major concepts of HRV measurements, their clinical relevance, and the recent advances in this field.<\/jats:p>","DOI":"10.1002\/clc.4960211005","type":"journal-article","created":{"date-parts":[[2009,2,4]],"date-time":"2009-02-04T02:30:19Z","timestamp":1233714619000},"page":"719-724","source":"Crossref","is-referenced-by-count":85,"title":["Current clinical applications of heart rate variability"],"prefix":"10.1002","volume":"21","author":[{"given":"A.","family":"Stys","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Stys","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,2,3]]},"reference":[{"key":"e_1_2_1_2_2","unstructured":"Von HallerA:Elements Physiologica p.330.
