The Study of an Exercise EGG Data Examine System

This paper introduced the development of an exercise electrocardiograph (ECG) data acquisition system which based on the treadmill exercise. The system consisted of treadmill, data acquisition box, and supervisory personal computer work station. The foremost characteristic of this system is that when we used treadmill to bring exercise stress, operator could control the resistance moment with the button on the data acquisition box or instruction from the supervisory controlled computer software and reduced or increased the work quantity of subject. The acquired ECG data and isochronous work quantity could be displayed, storaged, analyzed and played back on the computer. The data acquisition box would communicate with supervisory controlled computer via USB interface. For the demand of sickroom bed-side examination and data transmission, we even designed a data storage system with SD card for this system; it would storage the data into the SD card independently without computer. Besides, the acquisition box has the excellence of multifunctional, expandable and anti-jamming. As we perfecting the supervisory controlled computer software, the system could accomplish Holter examination, clinical 12-leads synchronous ECG examination, etc; it would satisfy the requirement of clinical ECG examination furthest.
