The real-time cardiac monitoring Robert is devised and prepared and electrocardiogram (ECG), heart rate, phonocardiogram (PCG) and dynamic three-dimensional echocardiography of a person can be recorded and displayed through touching the ECG signal acquisition sensor on the hands of the Robert. Furthermore, the CDMA wireless communication platform is adopted to transmit the difficult ECG to the service center, followed by diagnosing the ECG by doctors and transmitting the feedback diagnostic results. I-lead ECG of the person can be recorded by the amplification circuit with high gain and low noise. Then, the heart rate and output phonocardiogram are displayed and the model of heart beat is transmitted to the service center via CDMA platform. The displayed ECG is clear, and the stimulated heart beat is synchronous, which makes the person know his own heart information. Furthermore, ECG received by the service center is in accordance with the one recorded by the Robert.
