In this study, we aimed to develope the physio-module for echocardiography. This physio-module includes multi-functions such as ECG, respiration, PCG, heart sound, and this is used to diagnose a cardiac disease in using ultrasound images synchronized with biosignals of physio-module. In this paper, the developed physio-module was verified by applying various test patterns considering each biosignal's characteristics and we could get the performance of QRS trigger delay time within international standard, EC-13 criteria. And ECG's change in physio-module and blood flow in M-mode was synchronized.

In this study, we investigated the performance of real-time QRS complex detection algorithm in physio-module for echocardiography. The performance of QRS detection module in echocardiography was evaluated according to international standard, EC-13 and we compared with commercialized physio-module with QRS complex detection. In this study, we can get performance of QRS complex detection, pacer pulse detection, Tall t-wave rejection and arrhythmia detection within EC-13's criteria and we can get improved QRS trigger delay time and baseline wondering rejection times in compared with commercialized physio-module.
