A large color fully articulating screen shows your 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.

[list]          [*] Swivel screen - 12.1 inch touch panel TFT LCD with swivel screen lets you change the screen angle to the best viewing position.          [*] Same size display image and printout - The screen display and waveforms are the same size as the printout. Also, the display has grid lies just like the recording paper.          [*] Large 5 minute memory - The most recent five minutes of all lead ECG waveforms can be stored in memory. This increases the chance to record important data. To save data, you can select, analyze and print just the necessary region from 5 minute full disclosure.          [*] Serial comparison - Average waveforms in the latest 5 exams can be compared in the same screen. You can know the          changes in time-series basis.          [*] Communication capability - Approximately 400 patients x 10 seconds of 12 lead ECG wave and patient information can be          stored. Approximately 2,500 patients x 10 seconds of 12 lead ECG wave and patient information can be stored on a QM-040V flash disk card. Stored data can be transferred to PC via QM-040V or LAN/ Wireless LAN interface with optional QB- 903E ECG viewer software.          [/list]
