"Digital Fifteen-lead ECG"

With the aggravation of aged population, the health of the elder has become a top priority for young people. Regular physical examination is essential, and the most conventional detection is the ECG examination. ECG test can diagnose many diseases, such as coronary heart disease, myocardial ischemia, premature beats, atrial fibrillation and other cardiac diseases. With the increase of age, the probability of heart disease will increase a lot, therefore people need to do ECG detection regularly. The ECG machine has been smaller than the existing digital ECG machine, and has the faster processing speed, the more importantly is the addition of the respiratory signal3channels. The main work is as follows:(1) In order to figure fifteen-lead ECG to achieve better noise suppression, using double-circuit board design, the collection ends with the main control terminal separately, place the power supply module, ECG acquisition module, and communication interfaces on the down board, the main control module, memory module placed on the up board, then draw PCB circuit board through porte199E, soldering circuit debugging through the complete hardware design digital fifteen-lead ECG machine. Then through CCS3.3software programming and debugging the main control chip to achieve8-channel ECG machine ECG acquisition, real-time display, playback display, store ECG data and other functions.(2) Though VS2005PC programming software programming, complete the communication between PC and ECG achieve font downloading, uploading waveforms, software activation and filter settings function, and ECG housing production through solidworks3D mapping software, and then produced by the3D printer the enclosure, complete the overall design of ECG machine.(3) intentions electric detector for digital fifteen-lead ECG machine noise detection and accuracy testing, calibration work completed ECG machine. Finally, through the capture and playback of human electrocardiogram showed complete the filter settings ECG machine. The final completion of a portable digital fifteen-lead ECG.
