| Popis: | D ecreased heart rate variability (HRV) is generally associated with compromise of cardiovascular feedback systems (1,2). Changes in HRV can be caused by congestive heart failure (1), myocardial infarction (3,4), diabetic autonomic dysfunction (5), aging (6), anesthesia (7,8), and surgery (9–12). We report initial findings using new techniques to measure HRV that we believe warrant additional investigation in a broad range of conditions involving pain. The acute effect of pain to increase heart rate is well known. We hypothesized that there may be adaptive effects of chronic pain on the autonomic regulation of the cardiovascular system that could be reversed by analgesia, and we examined whether the acute relief of chronic pain affects HRV. We monitored several measures of HRV because these can differ in their ability to detect different conditions affecting the cardiovascular system (4,6,9,12–15). Traditional measures of HRV include sd (1,2). More recent measures estimate dimension (8,13,15,16) and entropy (6,8,9,15,17,18). |
