The proposed system is a DNN-based method of spectrogram with DAE and 1-AE can achieve higher accuracy when compared to other classification methods of S1 and S2 heart sounds.doi:10.1007/978-981-33-4046-6_24P. JyothiV. DilipVenkata Kumar...
Phonocardiogram (PCG), the digital recording of heart sounds is becoming increasingly popular as a primary detection system for diagnosing heart disorders and it is relatively inexpensive. Electrocardiogram (ECG) is used during the PCG in order to identify the systolic and diastolic parts manually. In...
sounds of closing heart valves was Rouanet of France, who wrote in his 1832 MD thesis that S1 occurred when the atrioventricular (i.e., mitral and tricuspid) valves closed, and S2 occurred when the semilunar (i.e., aortic and pulmonic) valves closed.2 THE FIRST HEART SOUND (S1) I...
Ensemble averaging has been widely used as a solution to wide-band noise problem for the first and second heart sounds. The need for a large number of samples of similar morphology, makes the ensemble averaging an inefficient method for this application. In the method presented here, an ensembl...
The Courtemanche segmentation algorithm used herein proposed the use of an adaptive threshold wavelet transform filtering technique used with Shannon energy, physiological factors and heart rate approximation to properly identify the first heart sounds (S1) and segment the heart signal. However, this met...
Systolic time intervals and heart sounds were studied in twenty patients with left bundle branch block. A definite cause for the organic heart disease was not ascertained. Abnormal duration of the electromechanical systole (Q-A2), due to a prolongation both of the preejection period (PEP) and ...
First, we built a small emotion heart sound database, and simultaneously recorded the participants’ ECG for comparative analysis. Second, according to the characteristics of the heart sound signals, two emotion evaluation indicators were proposed: HRV of heart sounds (difference between successive ...
