Heartbeat murmurs detection in phonocardiogram recordings via transfer learning

Alexandria Engineering Journal, 2022
Heart murmurs are abnormal heartbeat patterns that could be indicative of a serious heart condition, which can only be detected by trained specialists with the use of a stethoscope.

Enhanced Identification of Valvular Heart Diseases through Selective Phonocardiogram Features Driven by Convolutional Neural Networks (SFD-CNN)

Jurnal Nasional Teknik Elektro
Valvular Heart Disease (VHD) is a significant cause of mortality worldwide. Although extensive research has been conducted to address this issue, practical implementation of existing VHD detection results in medicine still falls short of optimal ...

A Comprehensive Nomogram Integrating Phonocardiogram and Echocardiogram Features for the Diagnosis of Heart Failure With Preserved Ejection Fraction. [PDF]

Clin Cardiol
A total of 204 patients and 49 features were collected. After splitting the population into training and test sets according to a ratio of 7:3, the LASSO and logistic regression was used to select the final five factors for a nomogram. The AUC for the nomogram model is 0.945, while the AUC for the echocardiographic parameters combined with NT‐proBNP in

Importance of fourth heart sound and preserved left atrial function in wild-type transthyretin amyloidosis. [PDF]

ESC Heart Fail
Abstract Aims A fourth heart sound (S4) was reported to be almost never present in patients with amyloid light‐chain cardiomyopathy. There have been no reports on S4 in patients with wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM). This study aimed to clarify the clinical implications of S4 in patients with ATTRwt‐CM.

Early diastolic heart sounds caused by the atrial kick. [PDF]

Ann Noninvasive Electrocardiol
Phonogram (top) demonstrates an early diastolic sound (arrows) which corresponds to the P‐wave on the EKG in a patient with second‐degree type I AV block. Abstract An 81‐year‐old male with a history of coronary artery disease, hypertension, paroxysmal atrial fibrillation and chronic kidney disease presents with asymptomatic bradycardia. Examination was

Exploring the Impact of Signal Quality Enhancement on Heart Sound Classification Models

IEEE Access, 2023
Limited cardiology resources increase the urgency for automated heart disease screening for the general public. Heart sound diagnostic models have been recently employed as a cost-effective solution for the initial screening of heart disease.
