To make it easier for the medical to monitor the ECG of their patients outside the hospital, we designed and developed an ECG monitoring and alarming system based on Android smart phone. In our system, an ECG device collects the ECG signal and transmits it to an Android phone. The Android phone detects alarms which come from the ECG devices. When alarms occur, Android phone will capture the ECG images and the details about the alarms, and sends them to the cloud Alarm Server (AS). Once received, AS push the messages to doctors’ phone, so the doctors could see the ECG images and alarm details on their mobile phone. In our system, high resolution ECG pictures are transmitted to doctors’ phone in a user-friendly way, which can help doctors keep track of their patient’s condition easily.展开更多

Methods: 146 patients with cardiovascular diseases in our department from January 2019 to December 2020 were taken as observation objects and divided into the first group and the second group. Remote real-time ECG monitoring and routine ECG monitoring were used respectively to compare the monitoring effects of the two kinds of ECG. Results: (1) the positive and negative detection rates of critical values in the first and second groups were 36.98% and 63.01% in the first group and 15.06% and 84.93% in the second group respectively (χ2 = 23.203,P = 0.000). The results were different. (2) In the comparison of the treatment time of ECG critical value between the first group and the second group, the first group is 7.56±1.64(min) and the second group is 7.85±1.72(min), (t = 0.538,P = 0.361), the results are not different. Conclusion: the remote real-time ECG monitoring for patients with cardiovascular diseases is effective, and this method can be popularized.展开更多
