OBJECTIVE To assess the cost-effectiveness of various strategies to evaluate heart murmurs in children. METHODS We modeled 6 strategies to follow the initial examination by the pediatrician: (1) refer suspected pathologic murmurs to a cardiologist, (2) obtain a chest radiograph (CXR) and electrocardiogram (ECG) and refer suspected pathologic murmurs to a cardiologist, (3) refer suspected path...

Heart sounds show chaotic and complex behavior when murmurs are present, containing nonlinear non-Gaussian information. This paper studies ways to extract features from dynamic models. The frequently used describe the underlying dynamics of heart derived dynamical modeling sound signals. study incorporates alongside conventional classifiers in analysis phonocardiograms (PCGs), achieving a signi...

BACKGROUND Detection of a heart murmur in healthy children is common, but may generate anxiety among parents. Many parents believe a heart murmur is a sign of heart disease, although the majority of heart murmurs are innocent. The purpose of this study was to assess anxiety and concerns in parents of children referred for evaluation of a heart murmur and to evaluate the effect of receiving a fa...

Coronary Artery Disease (CAD) is a leading type of heart disease in the world caused by the gradual build-up of plaque on the walls of the arteries. Due to CAD’s high incidence rate and mortality, it is very harmful to human health. CAD can develop slowly and silently over years without any symptoms. Early diagnose of CAD is one of the most important medical research areas. Diastolic murmurs th...

Diagnostic interpretation at auscultation of heart murmurs is accompanied by frequent errors. It creates serious clinical, pedagogical, organizational and social problems. The standard nosological principle of a clinical information description from the diagnosis (a disease name) to the description of symptoms/signs contradicts to real clinical practice from revealing of symptoms through differ...

murs was evaluated in 36 patients and the results compared with the effects of amyl nitrite and phenylephrine. The isometric handgrip exercise produced immediate, reproducible, and significant increases in heart rate and blood pressure. It also increased the intensity of murmurs due to aortic and mitral regurgitation and mitral stenosis and attenuated the murmurs of left ventricular outflow tra...
