CONVOLUTIONAL NEURAL NETWORK FOR ECG-BASED VIRTUAL PATHOLOGY STETHOSCOPE TRACKING IN PATIENT HEART AUSCULTATION by Haben Yhdego, Ph.D. Candidate in the Department of Computational Modeling and Simulation Engineering at Old Dominion University


Cardiac auscultation (CA) is the auditory detection of heart sounds to diagnose abnormalities, a crucial skill that is both efficient and cost-effective in medical practice. However, due to the increased prevalence and usage of expensive cardiac technologies, many new physicians and trainees have difficulty performing essential cardiac examinations on their patients, particularly diagnosing abnormalities through auscultation using a stethoscope. A virtual pathology stethoscope is a simulation-based solution that trains students to perform cardiac examinations by listening to abnormal heart sounds in otherwise healthy standardized patients (SPs). This study reports the accuracy of an electrocardiogram (ECG)-based stethoscope tracking method for placing virtual symptoms in correct auscultation regions. A modified stethoscope head with two electrodes was used to pick up ECG signals at the four primary auscultation sites. A one-dimensional convolutional neural network (CNN) is then modeled to classify the location of the stethoscope by taking advantage of subtle differences in the ECG signals. A 91% accuracy was obtained, showing promising performance gain over previous methods. This finding would significantly extend the simulation capabilities of SPs by allowing trainees to perform realistic CA and hear CA in a clinical environment.


Haben Yhdego is a Ph.D. candidate in the Computational Modeling and Simulation Engineering (CMSE) Department at Old Dominion University. He received MSc in Image processing and computer vision from Jean-Monet University, Saint-Etienne, France. His research interests include applying machine learning methods for wearable sensor signals, image analysis, and computer vision. He publishes some papers in IEEE and SpringSim-related to the application of machine learning
