“…Few studies have reported the reduction of HRV in diabetes. In diabetic patients without evidence of autonomic neuropathy, the reduction in heart rate variability during controlled conditions has also been reported 11,24,25 . Abnormal heart rate variability in diabetes represents an increased risk for ventricular arrhythmias, as well as total cardiovascular morbidity and mortality 12 .…”

“…The decrease in glycated hemoglobin and blood glucose recorded in IHD patients with diabetes and diabetic neuropathy indicates that regular prolonged breathing exercises can significantly improve the blood glucose homeostasis and the much-needed glycemic control among these patients. Hyperglycemia and its related metabolic consequences leads to the pathogenesis of autonomic neuropathy in diabetes 11,24 . The observed improvement in metabolic parameters could be attributed to the autonomic changes brought about by diaphragmatic breathing, which decreased the sympathetic activity 15,35,39,40 .…”

“…The efficacy of HRV as a prognostic indicator has been demonstrated in post-myocardial infarction studies [13][14][15][16], and its use in analysis of the extent of neuropathy due to non-insulin-dependent diabetes mellitus (NIDDM) has also been investigated [17]. Hence, the characterization of SCI population-specific changes in ANS function using HRV as a surrogate metric is a reasonable and logical application of this technique.…”

Spinal cord injury (SCI) patients are known to suffer from autonomic failure as a result of their injury. The magnitude of the dysautonomia resulting from such an injury is difficult to predict or characterize and, in varying degree, it impedes the recovery of physiological homeostasis. This study is intended to investigate the effectiveness of heart rate variability (HRV) analysis as a method of quantifying and characterizing autonomic function in patients with traumatic spinal myelopathy. HRV analysis was carried out in 13 male SCI patients (six tetraplegic, seven paraplegic) and 13 age-matched, able-bodied controls. Twenty-four hour ambulatory and sleep ECG tracings were obtained. Time domain, amplitude, and power spectral analyses were used to study HRV and autonomic function. Both tetraplegic (20+/-12 ms, mean+/-SD) and paraplegic (22+/-8 ms) subjects demonstrated significant loss of low frequency 24-hour HRV compared to able-bodied controls (36+/-14 ms, p < 0.05) and during sleep. This was interpreted as being consistent with predominantly sympathetic denervation uninfluenced by degree of physical activity. There were no significant differences between groups in parasympathetically mediated high frequency HRV. We conclude that HRV analysis is capable of distinguishing between SCI or able-bodied humans and among tetraplegic and paraplegic patients. Patterns of altered HRV may be useful in more completely characterizing or stratifying changes in physiology associated with injury level and may have diagnostic, prognostic, or therapeutic significance.

“…Accordingly, in a recent study of 21 patients with TLE who underwent a detailed 24 h ECG evaluation before undergoing epilepsy surgery, the preoperative heart rate variability was found to be associated with the postoperative seizure outcome, with significantly lower values in patients with poor outcome [44 ]. Reduced heart rate variability is a known risk factor for sudden death in patients without epilepsy [59]. Thus, there is a possibility that most of the preoperative SUDEP burden observed in refractory TLE is carried by patients who will eventually fail temporal lobe surgery, whereas those intended to be cured by surgery may have a low risk of SUDEP even before the operation [50].…”
