Parallelization of ECG template-based abnormality detection
In order to develop techniques to predict cardiac arrest, long-term study of electrocardiogram (ECG) data needs to be done to detect changes in electrical activity of diseased hearts. In the past, limitations of computing power and storage space restricted the duration of long-term studies to …
