Wireless ECG Monitoring system  features

The system amalgamates multiple advanced technologies of medicine and IT field and realizes the cardiogram monitoring of the patient Anytime Anywhere in the global range depending on the network resource around the world. The doctors do remote monitoring, analysis and conduction to the cardiogram signals, and thus reach the objectives of remote medical care, conducting illness at home and centralized administration of the patients, and annotate the new concept of network and digital monitoring.

The patients can timely get the diagnosis data or doctor's advice from the monitoring doctors and conveniently and rapidly enjoy cardiogram monitoring anytime and anywhere through the system; to abrupt malignant cardiovascular disease, the important relatives and monitoring doctors of the patients can be informed at the first time, and thus make the patients rapidly get effective treatment or saving in shortest time, greatly reducing the sudden death probability of the patients with cardiovascular disease.
