Our ECG Machine is the Three channels ECG Machine is such a kind of electrocardiograph, which samples 12 leads ECG signals simultaneously and prints out the ECG waveforms with thermal printing system. Its functions are recording and displaying ECG waveforms in auto/manual mode, auto-measuring and auto-diagnosing the ECG wave parameters, prompting the state of lead off and paper lack, switching the interface languages (Chinese/English), managing the case database and many more.
