| Summary: | 碩士 === 國立臺北科技大學 === 電機工程系所 === 95 === This research employs US Patent 6,638,232 B1 to develop a portable 12 leads electrocardiogram (ECG) signal measurement and monitoring system to help user real-time checking her/his ECG signal. The implemented Embedded Linux System has two main units: the ECG front-end unit, ECG displaying and calculating unit. The former consists of ECG signal acquisition circuit, ECG signal amplification circuit, and ECG signal A/D circuit. The latter is a measurement and monitoring subsystem, which calculates time/frequency domain responses of extracted ECG signal and displays the corresponding waveforms on LCD panel. By means of these waveforms, the US Patent 6,638,232 B1 can be used to locate heart disease. The software tools － QT and Qtopia are used to draw 12 leads ECG signal and to provide man/machine interface.
The proposed system supports 12 leads ECG signal real-time display, illustrations of ECG time-domain and frequency-domain responses. A series of experimentals is conducted by using ECG signals generated from ECG signal simulator, database of hospital, and volunteers. Experimental result indicates that this system has potential for practical application.
