Determinants of cardiac autonomic dysfunction in ESRD.
BACKGROUND AND OBJECTIVES Cardiovascular events are common in patients with ESRD. Whether sympathetic overactivity or vagal withdrawal contribute to cardiovascular events is unclear. We determined the general prevalence and clinical correlates of heart rate variability in patients on hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We collected baseline information on demographics,...
متن کاملCardiac autonomic dysfunction in Brugada syndrome.
BACKGROUND Patients with Brugada syndrome present with characteristic ECG abnormalities (atypical right bundle-branch block and ST-segment elevation) and life-threatening ventricular tachyarrhythmias despite structurally normal hearts. Involvement of the autonomic nervous system is suggested by the occurrence of ventricular tachyarrhythmias and sudden death at rest or during sleep and by change...
متن کاملDiabetic cardiac autonomic dysfunction: parasympathetic versus sympathetic.
BACKGROUND Diabetic cardiac autonomic dysfunction often causes lethal arrhythmia and sudden cardiac death. 123I-Metaiodobenzylguanidine (MIBG) can evaluate cardiac sympathetic dysfunction, and analysis of heart rate variability (HRV) can reflect cardiac parasympathetic activity. We examined whether cardiac parasympathetic dysfunction assessed by HRV may correlate with sympathetic dysfunction as...
متن کاملClinical study of cardiac autonomic dysfunction in HIV patients
Results In the present study, 16% of HIV +ve with the AIDS had abnormal autonomic dysfunction and 4% of HIV positive without AIDS had abnormal autonomic dysfunction. Reduced heart rate variability is the commonest manifestation of autonomic dysfunction noted in both HIV positive without AIDS and HIV positive with AIDS groups. Diastolic BP response to sustained handgrip has a limited role in dis...
متن کاملClinical values of electrocardiogram (ECG) in diagnosing cardiac autonomic dysfunction
This study aims to analyse the clinical efficacies of electrocardiogram (ECG) in diagnosing cardiac autonomic dysfunction (CAD) and to explore the clinical values of this method. A total of 82 CAD patients clinically diagnosed and confirmed were selected for the traditional Chinese medical treatment and psychological intervention. After three courses of treatment, their ECG were monitored, and ...
