Detection of Atrial Fibrillation using Coherency of Power Spectrum in Electrocardiogram

摘要

Atrial fibrillation (AF) is a disorder of the heart with fairly high mortality in adults. AF is a common heart arrythmia which is characterized by a missing or irregular contraction of atria. This article uses the method of power spectrum coherence as one of the characteristics of a signal used to detect atrial fibrillation atrium on electrocardiograph. This research was able to detect AF signal based on the coherence of the power spectrum. This method produces performance with accuracy, sensitivity, and specifications that is 63.98%, 65.02% and 63.55% respectively.
