Abstract

An atrial fibrillation (AF) monitor extracts two P wave features and an R-R interval feature from a sequence of ECG waveforms. The features are used by a classifier to classify a heart rhythm as AF or non-AF. The AF classification results may be further processed to reduce false alarm reporting. The AF classification results are used by an AF burden calculator to report AF burden in real time.
