2. An automatic segmentation method for heart sounds Full Text available with Trip Pro

that the boundary localization has a sensitivity (Se) of 100%, a positive predictive value (PPV) of 99.3% and an accuracy (Acc) of 99.93%. Moreover, the Se, PPV and Acc of component identification reach 98.63, 99.86 and 98.49%, respectively.The proposed method shows reliable performance on the segmentation of heart sounds. Compared with previous works, this method can be applied to not only normal heart sounds, but also the sounds with S3, S4 and murmurs, thus greatly increasing the applied range. (...) An automatic segmentation method for heart sounds There are two major challenges in automated heart sound analysis: segmentation and classification. An efficient segmentation is capable of providing valuable diagnostic information of patients. In addition, it is crucial for some feature-extraction based classification methods. Therefore, the segmentation of heart sound is of significant value.This paper presents an automatic heart sound segmentation method that combines the time-domain analysis

3. Multistage decision-based heart sound delineation method for automated analysis of heart sounds and murmurs Full Text available with Trip Pro

Multistage decision-based heart sound delineation method for automated analysis of heart sounds and murmurs A robust multistage decision-based heart sound delineation (MDHSD) method is presented for automatically determining the boundaries and peaks of heart sounds (S1, S2, S3, and S4), systolic, and diastolic murmurs (early, mid, and late) and high-pitched sounds (HPSs) of the phonocardiogram (PCG) signal. The proposed MDHSD method consists of the Gaussian kernels based signal decomposition (...) (GSDs) and multistage decision-based delineation (MDBD). The GSD algorithm first removes the low-frequency (LF) artefacts and then decomposes the filtered signal into two subsignals: the LF sound part (S1, S2, S3, and S4) and the high-frequency sound part (murmurs and HPSs). The MDBD algorithm consists of absolute envelope extraction, adaptive thresholding, and fiducial point determination. The accuracy and robustness of the proposed method is evaluated using various types of normal and pathological

is critically needed. Cardiac auscultation (listening to heart sounds) is possible option as heart sounds are associated with myocardial function and dysfunction .In a normal heart, two heart sounds (S1 and S2) are audible, corresponding to closure of the mitral and aortic heart valves respectively. A third heart sound S3, occurring after S2 is present in some heart failure. A fourth heart sound S4, occurring just before S1, is due to forceful contraction of the atrium to overcome a stiff or hypertrophic (...) , and Doppler ultrasound to create images of the heart.

The third heart sound is benign in youth, some trained athletes, and sometimes in pregnancy but if it re-emerges later in life it may signal cardiac problems, such as a failing left ventricle as in dilated (CHF). S3 is thought to be caused by the oscillation of blood back and forth between the walls of the ventricles initiated by blood rushing in from the atria. The reason the third heart sound does not occur until the middle third of diastole is probably
