Abstract:
1. A system of analyzing electrocardiogram wave data obtained from a subject, comprising: a wave identification unit that identifies an electrocardiogram wave from the obtained electrocardiogram wave data; a feature selection unit that selects a feature pattern including a feature when a cardiac massage has been performed with respect to the electrocardiogram wave data of the electrocardiogram wave identified by the wave identification unit; a generation unit that generates a component of the cardiac massage using the feature pattern selected by the feature selection unit; a removal unit that removes, from the obtained electrocardiogram wave data, the component of the cardiac massage generated by the generation unit, and a storage unit that stores a plurality of different registration feature patterns in advance, wherein the feature selection unit refers to the registration feature patterns stored in the storage unit to select the registration feature pattern that is the most similar to the feature pattern included in the electrocardiogram wave data of the electrocardiogram wave identified by the wave identification unit, the electrocardiogram wave data includes a wave of which the feature when the cardiac massage has been performed is represented as an amplitude component, the storage unit stores the registration feature patterns configured using a normalization distribution and thresholds that have been statistically collected, including, as the amplitude component, the feature when the cardiac massage has been performed, and the feature selection unit extracts the amplitude component from the electrocardiogram wave data of the electrocardiogram wave identified by the wave identification unit, and also cross-checks the extracted amplitude component with amplitude components of the registration feature patterns stored in the storage unit to select the registration feature pattern of which the amplitude component is the most similar to the extracted amplitude component.
