ABSTRACT
<p><b>OBJECTIVE</b>A remote wireless electrocardiogram (ECG) monitoring system is designed by using the CC2530 micro-controller as the device core.</p><p><b>METHODS</b>Acquisition, conversion and data processing for ECG signals are realized on CC2530 micro-controllers. And the ECG data is transmitted to the coordinator by using ZigBee. It realizes the real-time monitoring of ECG signals and heart rate variability (HRV) data.</p><p><b>RESULTS</b>The test results show that the maximum error of the designed ECG monitoring analyzer is 3 beats per minute and the average error is 1.6 beats per minute, which can meet the requirement of pharmaceutical industry standards of the People's Republic of China.</p><p><b>CONCLUSIONS</b>The ECG monitoring analyzer has good portability, high measurement precision and good practical application values.</p>
