A ECG600G 6 Channel ECG Machine prints 6 waveform in one go. So its paper width is wide as compare to 3 channels ECG Machine. So the print format of 6 channels ECG Machine would be 6x2. 6 channel ECG Machine report length is comparatively less because page width is large. In a 6 channel ECG Machine, 6 waveforms are printed simultaneously, so 12 waveforms can be printed in just 2 slots of the paper. ECG600G 6 Channel ECG Machine is very effective.
