We have developed a telemedicine system to monitor a patients electrocardiogram (ECG) and heart sounds (PCG) during daily activity. The complete system, consisting of an ECG recorder, an accelerometer and a 2.4 GHz low power mobile phone, is mounted on three chest sensing electrodes. The accelerometer records the PCG produced by closing of the mitral and aortic valves (S1 and S2). The sampled ECG and PCG are stored in the system for two minutes and continuously updated. When a patient feels heart discomfort such as angina or an arrhythmia, he/she pushes the data transmission switch on the system. The ECG and PCG for the next two minutes are stored in the system, and then the system then sends the four minutes of stored data directly to a hospital server computer via the 1.9 GHz low power mobile phone. These data are stored on the server and then downloaded to the physicians Java configured mobile phone. The physician can then check the patients cardiac condition, regardless of patient or physician locations, and then take appropriate actions.
我们开发了一种远程医疗系统，用于在日常活动期间监测患者的心电图（ECG）和心音（PCG）。整个系统由一台心电图记录仪、一个加速度计和一部2.4 GHz低功率移动电话组成，安装在三个胸部传感电极上。加速度计记录二尖瓣和主动脉瓣关闭时产生的心音（S1和S2）。采样的心电图和心音在系统中存储两分钟并持续更新。当患者感到心脏不适，如心绞痛或心律失常时，他/她按下系统上的数据传输开关。接下来两分钟的心电图和心音存储在系统中，然后系统通过1.9 GHz低功率移动电话将存储的四分钟数据直接发送到医院服务器计算机。这些数据存储在服务器上，然后下载到医生配置了Java的移动电话上。然后，无论患者或医生身在何处，医生都可以检查患者的心脏状况，并采取适当行动。
