Heart rate variability and heart rate recovery as prognostic factors
BACKGROUND AND AIM Heart rate (HR) can appear static and regular at rest, during exercise or recovery after exercise. However, HR is constantly adjusted due to factors such as breathing, blood pressure control, thermoregulation and the renin-angiotensin system, leading to a more dynamic response that can be quantified using HRV (heart rate variability). HRV is defined as the deviation in time b...
متن کاملPrognostic significance of PVCs and resting heart rate.
BACKGROUND We sought to evaluate the prognostic significance of premature ventricular contractions (PVCs) on a routine electrocardiogram (ECG) and to evaluate the relationship between heart rate and PVCs. METHODS Computerized 12-lead ECGs of 45,402 veterans were analyzed. Vital status was available through the California Health Department Service. RESULTS There were 1731 patients with PVCs ...
متن کاملPredictors of heart rate variability and its prognostic significance in chronic kidney disease.
BACKGROUND Heart rate variability (HRV), a noninvasive measure of autonomic dysfunction and a risk factor for cardiovascular disease (CVD), has not been systematically studied in nondialysis chronic kidney disease (CKD). METHODS HRV was assessed using 24-h Holter monitoring in 305 subjects from the Renal Research Institute-CKD Study, a four-center prospective cohort of CKD (Stages 3-5). Multi...
متن کاملeffect of cardiac rehabilitation program on heart rate recovery in coronary heart disease
background: it has been suggested that the autonomic system function and the metabolic syndrome can significantly affect patients' survival. the aim of the current study was to investigate the impact of the cardiac rehabilitation program on the autonomic system balance in patients with coronary artery disease. methods: patients with a previous diagnosis of coronary artery disease who were refer...
متن کاملValvular heart disease.
Era Before 1950 In 1950, rheumatic valvular heart disease (VHD) was the most common cause of VHD. The link between streptococcal infection and rheumatic fever was established, and a successful trial of penicillin prophylaxis against rheumatic fever was reported.1 In 1944, Jones published a seminal article on diagnosis of rheumatic fever.2 The American Heart Association (AHA) and Circulation pla...
