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 ...

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 ...

Diagnostic performance of coronary artery disease prediction model (CAD-score system) based on phonocardiogram: a systematic review and meta-analysis [PDF]
Frontiers in Cardiovascular MedicineIntroductionPre-test probability stratification of individuals with suspected obstructive coronary artery disease (CAD) has remained suboptimal for many years. Consequently, the majority of diagnostic tests used to rule out CAD exhibit normal results. An
