The Cardiofax M (ECG-3350) is an electrocardiograph with an 8.0-inch colour screen and the ECAPS 12C analysis program. Waveform processing works at 500 samples/s and, with the optional software QP-230E, the unit offers a synthesised 18-lead ECG (synECi18). Data can be output via LAN, USB or SD card in DICOM or PDF format.
