Classic Murmur, Unexpected Diagnosis: A Case Report and Pathophysiological Review. [PDF]

Case Rep Cardiol
A systolic murmur best heard at the aortic area with radiation to the neck is considered a hallmark of aortic stenosis. We report a patient with this auscultatory pattern in whom investigation revealed an unexpected diagnosis. Accompanying symptoms reinforced the initial suspicion, adding another layer of complexity to the diagnostic process. This case

Dynamic Changes in Fourth Heart Sound in Type 2 Diabetes: Insights From Visualized Phonocardiography and SGLT2 Inhibitor Adjustment. [PDF]

Case Rep Med
The fourth heart sound (S4) is an auscultatory marker of left ventricular diastolic dysfunction (LVDD). Additionally, S4 correlates with atrial function, which is typically impaired in patients with Type 2 diabetes (T2D) but can improve with sodium–glucose co‐transporter‐2 inhibitor (SGLT2i) therapy.

Use of proposed systolic and myocardial performance indices derived from simultaneous ECG and PCG recordings to assess cardiac function in healthy Beagles [PDF]

Veterinary World, 2022
Background and Aim: Cardiac time intervals (CTIs) can provide important information on the electrical and mechanical properties of the heart. We hypothesized that cardiac function can be described using the combined power of electrocardiography (ECG) and

Automated Assessment of the Quality of Phonocardographic Recordings through Signal-to-Noise Ratio for Home Monitoring Applications

Sensors, 2021
The signal quality limits the applicability of phonocardiography at the patients’ domicile. This work proposes the signal-to-noise ratio of the recorded signal as its main quality metrics.

Absent fourth heart sound as a marker of adverse events in hypertrophic cardiomyopathy with sinus rhythm

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.

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.
