Nihon Kohden’s Model 1550A Cardiofax V Electrocardiograph offers a large color, fully-articulating screen that shows a patient’s ECG the exact same size as it is printed on the internal thermal calibrated sheet, complete with an on-screen grid. A visual keyboard pops up on the TFT LCD touch screen for speedy patient data entry, or an external keyboard can be plugged into the back of the unit. Interpretation is standard with the model 1550 electrocardiograph as is LAN, USB, and flashcard data communication, bar coding software, along with internal memory to store 400 patient ECG records.
The built-in thermal printer features a high-resolution four column by three row and a rhythm strip at the bottom print out, with patient demographic information, measurements, and interpretation printed over the ECG waveforms for a full sized printed sheet.
A five-minute memory allows the user to select the best ECG over a five-minute interval for the report, which can be helpful for obtaining a good ECG for less than compliant pediatric patients.
The device has an optional 15-lead capability. The device has a four-year warranty.
