Absent fourth heart sound as a marker of adverse events in hypertrophic cardiomyopathy with sinus rhythm [PDF]
Annals of Noninvasive Electrocardiology, 2022 Background Patients with hypertrophic cardiomyopathy (HCM) in sinus rhythm commonly show the fourth heart sound (S4). The lack of S4 may be a marker of impaired atrial function in HCM patients with sinus rhythm.

Phonocardiography based pulse wave velocity system for non-occlusive assessment of arterial stiffness [PDF]
Frontiers in Cardiovascular MedicineArterial stiffness is strongly associated with vascular aging and pathology and can be assessed in many ways. Existing devices for measuring central arterial stiffness, such as carotid-femoral pulse wave velocity (PWV), are limited by high costs and the ...

The Evolving Stethoscope: Insights Derived from Studying Phonocardiography in Trainees [PDF]
SensorsPhonocardiography (PCG) is used as an adjunct to teach cardiac auscultation and is now a function of PCG-capable stethoscopes (PCS). To evaluate the efficacy of PCG and PCS, the authors investigated the impact of providing PCG data and PCSs on how ...

A comparative study of single-channel signal processing methods in fetal phonocardiography.
PLoS ONE, 2022 Fetal phonocardiography is a non-invasive, completely passive and low-cost method based on sensing acoustic signals from the maternal abdomen. However, different types of interference are sensed along with the desired fetal phonocardiography.
