Intracardiac Signal의 스펙트럼 분석을 통한 Atrium Tachycardia 및 Fibrillation 검출

Detection of atrial tachycardia and fibrillation using spectrum analysis of intracardiac signal

Detection methods for atrial tachycardia and fibrillation on the time axis have the advantages of light operational load and are easy to apply to various applications. Despite these advantages, arrhythmia detection algorithm on the time axis cannot stand much noise such as motion artifacts, moreover the peak detection algorithm has high complexity. In this paper, we use a spectrum analysis method for the detection of atrial tachycardia and fibrillation. By applying spectrum analysis and digital filtering on obtained electrogram signals, we can diagnose heart arrhythmia without using peak detection algorithm.
