As a contribution to the George B. Moody PhysioNet Challenge 2022 we (team listNto urHeart) propose a phonocardiogram classifier. Based on the assumption that these recordings bear similarity to music, we borrow methods from the field of computational music analysis. In contrast to end-to-end machine learning approaches, we propose a carefully-crafted processing pipeline for automatically detecting single heartbeats in phonocardiogram recordings which are then classified by a bi-directional long short-term memory network. Our approach has the advantage of not requiring manual annotations during training, therefore alleviating the lack of annotated training data. In murmur detection, we reached a weighted accuracy of 0.68 in validation, 0.668 in test (rank: 25/40) and 0.64 ± 0.08 during training. In predicting patient outcome, we reached 10, 362 in validation, 13, 866 in test (rank: 27/39) and 11, 386 ± 2, 108 during training. The results indicate that borrowing algorithms from computational music analysis could bear the potential to address challenges in phonocardiogram classification successfully.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
