Abstract of the Talk: Artificial Intelligence (AI) tools are increasingly gaining popularity within the biomedical community for automated detection of various cardiovascular disorders. In medical applications, AI methods attempt to cluster patient traits or infer the probability of the disease outcome. Cardiovascular disorders have three basic origins. They are conduction abnormalities, myocardial abnormalities and valve related abnormalities. These three abnormalities are interrelated and they lead to different cardiac disorders. In clinical settings, cardiovascular abnormalities are diagnosed using electrocardiogram (ECG) signal and phonocardiogram (PCG) signal, as well as medical context including patient symptoms, medical history, and risk factors. These pieces of information are generally found in electronic health records (EHR). Analysis of such data requires natural language processing (NLP) techniques to extract information from such as clinical notes/medical journals to supplement and enrich structural medical data. The challenges in this area include not only processing of time series data such as ECG and PCG but also analyzing the textual data. In this presentation, we will discuss the significance of diagnostic information in ECG signal, heart sound signal or Phonocardiogram (PCG) and electronic health records (EHR). Some applications of state-of-art AI techniques in this area will be discussed.
