Heart rate variability (HRV) is traditionally derived from RR interval time series of electrocardiography (ECG). Photoplethysmography (PPG) also reflects the cardiac rhythm since mechanical activity heart coupled to its electrical activity. Thus, theoretically, PPG can be used for determining between successive heartbeats and variability. However, wave lags behind ECG signal by required transmission pulse wave. In this study, finger-tip standard lead II were recorded five minutes 10 healthy...

Many studies have reported, as effects asthma, significant improvements pulmonary functions, quality life and reduction airway hyper-reactivity, frequency attacks medication use. In addition, few attempted to understand exercise-induced bronchoconstriction (EIB) or exercise tolerance capacity. However, none these has investigated any immunological mechanisms by which improves variables The present...

Persons with epilepsy are afflicted comorbidities such as stigma, anxiety, and depression which have a significant impact on their quality of life. These remain largely unaddressed in resource-limited countries. This randomized controlled trial (RCT) aimed to investigate whether yoga psychoeducation were effective reducing felt stigma (primary outcome), neuropsychiatric outcomes, seizure frequency, compared sham persons epilepsy.

Approximate entropy (ApEn) and sample (SampEn) are the promising techniques for extracting complex characteristics of cardiovascular variability. Ectopic beats, originating from other than normal site, artefacts contributing a serious limitation to heart rate variability (HRV) analysis. The approaches like deletion interpolation currently in use eliminate bias produced by ectopic beats. In this study, R–R interval time series 10 healthy acute myocardial infarction (AMI) patients were...

In end-stage renal disease (ESRD) patients, the most common cause of mortality and morbidity are cardiovascular events. This could be attributed to impaired baroreflex function observed in this group patients. The effect transplantation (RT) on sensitivity (BRS) ESRD patients has been inadequately addressed. Therefore, we investigated its relation arterial stiffness indices variability parameters (heart rate blood pressure variability--HRV BPV) before after decipher underlying mechanism...
