The DR181 is the latest version of the reliable and popular DR180 series. The DR181 in a 12-lead configuration provides a high quality research and clinical evaluation tool. It records 12-lead / 9 channels of data – no short-cuts!

Northeast Monitoring’s 12-lead system does not use arithmetically derived or reconstructed data from non-standard Holter lead hook-ups. These short-cut methods may capture accurate data for normal beats, but the picture degrades sharply for virtually all morphologies of interest.

The DR181 12-lead settings can be adjusted to fit your 12-lead recording requirements. Intervals and strip lengths are adjustable, and you can also choose to record continuously in all 12-leads at a resolution of 12 bits per sample.


  • Meet EC-11 (American National Standard for Electrocardiographic devices) and EC-38 standards
  • All-digital recording eliminates mechanical malfunctions and makes the DR181 more reliable than cassette recorders
  • Removable digital memory (compact flash card) allows immediate re-use of the DR180+
  • Electronic storage of patient identification number prevents confusion of patient records
  • During hook-up, LCD displays actual ECG on all channels, eliminating the need for an ECG test block.
  • Pacemaker detection is standard
  • LCD displays percent of battery life during hook-up
  • Recorder can display in multiple languages (see brochure)
  • High resolution modes can be selected for pediatric patients
  • Shielded patient cables (significantly reduce electrode artifact) include either 5, 7, or 10 lead electrode option
