Apparatus and method for generating atrial fibrillation prediction model, and apparatus and method for predicting atrial fibrillation
An apparatus and a method to generate an atrial fibrillation prediction model, and an apparatus and a method to predict atrial fibrillation are provided. An atrial fibrillation (af) prediction model generating apparatus includes a feature extractor configured to extract t-wave features in a predetermined time period from electrocardiogram data and generate a t-wave feature profile based on the extracted features, and a prediction model generator configured to classify the generated t-wave feature profile and generate an af prediction model using the classified feature profile..

Atrial fibrillation classification using power measurement
An atrial fibrillation classification system collects celectrocardiogram signals and converts them to a frequency, time, or phase domain representation for analysis. An evaluation stage extracts energy density profile over a range of frequencies, time intervals, or phases, which is then summed and normalized to form dispersion metrics.
