The aim of this study is to show that the measures derived from Electrocardiogram (ECG) signals many a time perform better than the same measures obtained from heart rate (HR) signals. A comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ECG signals and HR signals, and thereby discriminate between normal and cong...

background: selenium (se) is an essential trace element mainly obtained from seafood, meat, and cereals. se deficiency has been identified as a major contributing factor in the pathogenesis of certain congestive heart failure (chf) syndromes. since there is controversy over the prevalence of se deficiency among patient with chf, the aim of this study was to assess the serum se concentrations in...

Heart rate variability (HRV) analysis has quantified the functioning of the autonomic regulation of the heart and heart's ability to respond. However, majority of studies on HRV report several differences between patients with congestive heart failure (CHF) and healthy subjects, such as time-domain, frequency domain and nonlinear HRV measures. In the paper, we mainly presented a new approach to...

when i first met this nice lady, i was in an evening work shift of ccu. this 69 years-old woman had been referred recently to our ward. she had a pale and puffy face. she suffered from chf. she had a normal breathing, but her ankle was swollen.   we stabilized her condition easily but, it was just the first step in her treatment way. prevention of recurrence of heart attack was our goal. every ...

During a period of four years between June, IS, 1988 to June, IS, 1992 one hundred and fourteen patients with congestive heart failure (CHF) were admitted to the pediatric department of Taleghani General Hospital. During the above period, 192 patients with heart disease were hospitalized at this department and CHF was the cause of admission in 59.4% of them. Congenital heart disease (CHO) w...

There is no uniformly accepted clinical definition for congestive heart failure (CHF), although criteria have been published by various groups. There is also no reference standard for CHF, although left ventricular ejection fraction (LVEF) gives a quantitative assessment of systolic function and is useful in predicting prognosis. To determine the relationship between LVEF and clinically diagnos...

1024x768 normal 0 false false false en-us x-none fa background : heart failure is a common health problem with poor prognosis. the gold standard for diagnosis is echocardiography but it is not always reachable, especially in emergency conditions. nt-pro-brain natriuretic peptide (nt-probnp) is a novel indicator for the diagnosis of heart failure and is being used in routine tests in emergency r...
