Abstract
Disclosed are a method and device capable of diagnosing arrhythmia by a contactless method by using a UWB radar. The method for diagnosing arrhythmia using a UWB radar disclosed herein comprises: a step of extracting a radar signal corresponding to a heartbeat component, from radar signals received after being reflected from an examinee; a step of analyzing a frequency component of the radar signal corresponding the heartbeat component; and a step of determining if the examinee has arrhythmia, on the basis of the magnitude of the value of the ratio between the largest peak value and the second largest peak value which are included in the frequency component.
Claims10
An arrhythmia diagnosis method using a UWB radar, the arrhythmia diagnosis method comprising:
- extracting a radar signal corresponding to a heartbeat component from radar signals reflected off and received from a patient;
- analyzing a frequency component of the radar signal corresponding to the heartbeat component;
- and
- determining whether or not the patient has arrhythmia according to a magnitude of a ratio value between a maximum peak value and a second largest peak value included in the frequency component.
An arrhythmia diagnosis method using a UWB radar, the arrhythmia diagnosis method comprising:
