Heart sounds are produced from a specific cardiac event such as closure of a valve or tensing of a chordae tendineae. Many pathologic cardiac conditions can be diagnosed by auscultation of the heart sounds. Note that heart sounds are discrete, short audible events from a specific cause — diff...
As a result of the research, it is seen that the classification performance criterias obtained with the proposed method are as similar as the segmented classification. Thus, it was concluded that the instant energy of the heart sounds, and a stacked autoencoder networks can be very easily used...
阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。1((die) of a broken heart sounds like the ending of a
Finally, SVM was employed for classifying heart sounds. The proposed method does not require the manual selection of features and identification and location of heart sound, nor does it suffer from some drawbacks of deep learning methods that require large amounts of training data. This method ...
Heart “murmurs”may be readily heard by a physician as soft swishing or hissing sounds that follow the normal sounds of heart action. Murmurs may indicate that blood is leaking through an imperfectly closed valve and may signal the presence of a serious heart problem.Coronary heart disease, in...

The heart sounds represent the typical "lub-dub" sound heard through a stethoscope that a physician would use. These sounds are able to provide valuable insight into the health of the heart and may indicate cardiovascular problems if the sounds have chan...
WHILST every one knows that the action of the heart ** is accompanied by sounds described as the first and second sounds of the heart, it is a remarkable fact that the mechanism by which the former of these phenomena is produced remains undetermined. It may be said to be almost ...

The heart sounds are extracted from the raw data with a very frequency-selective bandpass filter. Afterwards, the sound signal is enveloped by a Hilbert filter. The subsequent maxima detection block calculates the discrete point in time which represents the maximum amplitude of the heart sound. ...
