Overview

Enjoy simplicity and reliability – two of the hallmarks of the CardioMem CM 4000 ECG recorder.

This handy, lightweight recorder supports the user throughout all phases of recording and analysing Holter ECGs, from applying the electrodes and entering patient demographic data up to inspecting the ECG waveforms.

Advanced technology reduces the risk of corrupted or shortened recordings and minimizes the costs and troubles of repeat examinations.

Benefits

Get advanced technology, simple enough for everyday use. 

  • Handy and lightweight design offers protection against dust and splashed water.
  • Special features reduce the risk of corrupted or shortened recordings and minimize extra costs and time associated with repeat examinations:
    • Faulty electrode detection.
    • Continuous battery monitoring.
  • Auxiliary information acquired simultaneously can aid in the final diagnosis:       
    • Transthoracic impedance variations (shows respiration activity during sleep).
    • Pacemaker function.
  • Large, colour display with touch screen offers an overview of all the necessary information.
  • Intuitive user menus. 
  • Choose between 5- or 7- lead patient cables for different types of recording.  
  • Integrated Bluetooth* module allows encrypted, bidirectional data transfer for wireless set up. Patient demographic data can be: 
    • Wirelessly transferred to the recorder. 
    • Entered manually using the recorder interface provided.
    • Dictated through the built-in voice recorder.
  • After recording, transfer the file to a PC via hi-speed USB interface.
