This specification applies to the calibration of ECG function parameters and motion speed parameters of the sports tablet.

2 reference files

This specification refers to the following documents. JJG543-2008 ECG machine JJG1041-2008 digital electrocardiograph JJG1042-2008 dynamic (removable) electrocardiograph YY1139-2013 ECG diagnostic equipment For dated references, only dated versions apply to this specification; for undated references, The latest version (including all amendments) applies to this specification.

3 terms and units of measure

3.1 sports tablet exercisetreadmil It is a kind of heart that uses signal processing to effectively measure the ECG characteristic parameters generated by the motion plate test. Electrical diagnostic equipment. By analyzing the exercise electrocardiogram, the corresponding relationship of various ECG parameters is determined to assist the medical staff. The staff diagnosed coronary heart disease. 3.2 exercise plate test treadmilexercisetest Also known as exercise load test, it is to increase the load of the heart through grading exercise, so that the oxygen consumption of the heart is increased. Myocardial ischemia is induced when the load reaches a certain amount, and the diagnosis of coronary heart disease is assisted by the results of electrocardiogram examination.

4 Overview

The sports tablet is based on the motion ECG analysis system, which realizes the standard simultaneous acquisition of ECG signal 12-lead, mainly by ECG signal acquisition, transmission, reception, analysis, tablet control and other systems. The motion tablet is divided into wired and wireless according to the ECG signal transmission and reception methods.

5 Measurement characteristics

5.1 Calibration voltage The maximum allowable error is ±5%. 5.2 Voltage measurement The maximum allowable error is ±101 U1 Uin ÷% calculation (where U1 is the minimum value of the voltage measurement range, ie 0.1mV). 5.3 Polarization resistance voltage After applying a DC polarization voltage of ±300 mV, the baseline should be free of significant offset and the amplitude variation should be within ±5%. ......
