Identification of decompensation episodes in chronic heart failure patients based solely on heart sounds

open access: yesFrontiers in Cardiovascular Medicine, 2022
Decompensation episodes in chronic heart failure patients frequently result in unplanned outpatient or emergency room visits or even hospitalizations. Early detection of these episodes in their pre-symptomatic phase would likely enable the clinicians to ...

Denoising method of heart sound signals based on self-construct heart sound wavelet

open access: yesAIP Advances, 2014
In the field of heart sound signal denoising, the wavelet transform has become one of the most effective measures. The selective wavelet basis is based on the well-known orthogonal db series or biorthogonal bior series wavelet. In this paper we present a
