A 72-year-old man with calcific aortic stenosis and complete heart block was noted to have an intermittent diastolic murmur. Using combined echocardiography and phonocardiography, it was demonstrated that the murmur occurred while the mitral valve was closing. This suggested that antegrade flow across a closing mitral orifice is of etiologic importance in the production of the murmur. Atrial so...

Absolute Pitch (AP) is the ability to identify or categorize musical pitches accurately without an external reference. Although AP is generally thought to be rare, music psychology research in the past few decades has debated on every aspect of the phenomenon. This chapter will review the theories, methods, and findings on Absolute Pitch from the cognitive psychology and neuroscience literature...

The project is focused around designing a system that detects the cardiac murmur. So much work has already done in this field and all are efficient but when it comes to cost all of them seems to be costly for a normal people. Thus a system is to be designed that detects the cardiac murmur easily and that is simple to construct and operate. The whole concentration is on accuracy satisfaction and...

Heart murmur recognition and classification play an important role in the auscultative diagnosis. The method based on hidden markov model (HMM) was presented to recognize the heart murmur. The murmur was isolated on basis of the principle of wavelet analysis considering the time-frequency characteristics of the heart murmur. This method uses Mel frequency cepstral coefficient (MFCC) to extract ...

OBJECTIVE Congenital heart disease (CHD) is the most common form of cardiovascular diseases in children. This study was performed from September 2006 to August 2007 in Ardebil, Westnorthern Iran. The aim was to determine the prevalence of heart murmur in newborns and its correlation with CHD. METHODS In a 1-year cross sectional descriptive-analytic study, 2928 newborns were screened for heart...

INTRODUCTION Accidental murmurs occur in anatomically and physiologically normal heart. Accidental (innocent) murmurs have their own clearly defined clinical characteristics (asymptomatic, they require minimal follow-up care). AIM To point out the significance of auscultation of the heart in the differentiation of heart murmurs and show clinical characteristics of accidental heart murmurs. ...
