Ameya360 heart rate monitor solution designed a set of practical portable mobile ECG monitoring system

Electrocardiogram (ECG) is an important tool for the diagnosis of heart disease. Conventional electrocardiogram is a short-term ECG recorded by the hospital's electrocardiograph when the patient is lying still. Because heart attacks are very accidental and sudden, it is necessary to do routine ECG examinations to obtain disease information during the non-attack period. The odds are very low.

Therefore, it is of great practical significance to extend the ECG monitoring from the bedside and the hospital to the home to realize real-time remote monitoring. The rapid popularization of the Internet, especially wireless networks, has promoted the increasingly mature conditions for the application of embedded technology. In addition, the importance of ECG monitoring to the diagnosis of heart disease also makes remote monitoring a realistic possibility.

Program overview

The Ameya360 heart rate monitor solution has designed a practical portable mobile ECG monitoring system. Through this system, the patient's ECG signal can be wirelessly sent to the PC in the hospital via the GPRS network, or the ECG data can be stored in the system first, and then high-speed playback can be realized via USB.

The system consists of three parts: ECG monitor, communication network and monitoring center. In the overall hardware design, the high-performance microprocessor is used as the core, and the external interface is used to expand 512K parallel Flash and 512K SRAM, the storage space reaches 1M, and the USB interface is expanded. Use serial interface to expand serial Flash, A/D conversion and wireless module MC35. The ECG waveform can be accurately drawn on the computer screen, which is recognized by doctors of the Second Affiliated Hospital of China Medical University and can be used as a basis for clinical diagnosis; the system is highly practical, small in size, and economical and convenient. Patients can monitor the heart in real time anytime and anywhere, without being restricted by time and space; the wireless transmission function of this system can transmit ECG data to the hospital for diagnosis in real time, which greatly improves the efficiency of first aid.
