Abstract:
1. A wearable sensor device for heart performance characterization and abnormality detection, comprising: an interface for receiving sampled data representing an electrical signal indicating electrical activity of a patient heart over a plurality of heart beat cycles; a signal processor for using the received sampled data in determining a first electrocardiogram morphological signal value and its discrete wavelet transformed (DWT) value over a plurality of heart cycles; a comparator for comparing the first electrocardiogram morphological signal value and its discrete wavelet transformed (DWT) value with a threshold value to provide a comparison indicator; a patient monitor that in response to said comparison indicator indicates a calculated signal value exceeding the threshold value, and generates an alert message associated with the threshold, a first module, wherein the first module provides data relating to measurement of change of an St-segment, QT interval or T wave and a second module, wherein the second module classifies heart beats as premature ventricular contraction, premature atrial contraction, fusion, right bundle branch block, left bundle branch block or normal using semi-supervised learning algorithms that are created from data derived from the patient's heart beats.
