Wireless electrocardiogram (ecg) system for medical diagnostics

A wireless electrocardiogram (ECG) system for medical diagnosis, comprising:

• a smart terminal;
• a plurality of lead front ends, each lead front end being coupled with a corresponding body surface electrode configured to be attached to a chest of a subject for collecting ECG/biopotential signals;
• and
• a bidirectional wireless communication channel established between each lead front end and the smart terminal for independent bidirectional information transmission;
• wherein the wireless ECG system is configured to have a simulation testing mode and an actual measurement mode, such that close-loop adaptive ECG information collection and process are achieved by switching between the simulation testing mode and the actual measurement mode online in real time;
• wherein when in the simulation testing mode, the smart terminal first acts as a signal source to synchronously send a calibration/digitized ECG signal as an input reference signal to each lead front end through the bidirectional wireless communication channel, and the information obtained by the lead front end for detecting the reference signal is transmitted back to the smart terminal through the bidirectional wireless communication channel, and the smart terminal then compares and calibrates the reference signal detected by each lead front end with the calibration/digitized ECG signal originally sent and generates the test response curve of each channel;
• wherein when in the actual measurement mode, the ECG/biopotential signal collected by each body surface electrode is pre-processed by the lead front end connected to one by one, and then uploaded to the smart terminal through the bidirectional wireless communication channel, and the smart terminal corrects the ECG data actually measured by each lead in real time based on the response curve to obtain an ECG report and output it.
