DR181 Digital Holter Recorder, 12-lead

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.
A number of key features make our recorders the quality and technology leaders in the industry today. Contact NorthEast or read on for more details.
“… the Gold Standard for our laboratory, ...used in over 200 clinical sites world-wide for continuous monitoring research in acute MI patients.”

  • Meets EC-11 and EC-38 standards
    Meets applicable sections of ANSI/AAMI EC11-1991 “Diagnostic Electrocardiographic Devices” and ANSI/AAMI EC38-1994 “Ambulatory Electrocardiographs.”
  • Ergonomic design
    Large, easy view screen and soft-keys make the unit exceptionally easy to use. The large Event marker button operates in conjunction with interactive and customizable patient diary via user-programmable soft-keys.
  • Proven reliability
    Thousands of Holter units are in use worldwide. Real-world experience is designed into every unit.
  • Maximize Holter reimbursements
    Our system allows your office to “capture” reimbursement for all applicable CPT (Current Procedural Terminology) codes for Holter. Removable digital storage memory (compact flash) allows rapid re-deployment of the unit to the next patient.
  • Reduce artifact with shielded cables
    Shielded cables provide better signal integrity and noise immunity. Our cables are carefully shielded and impedance matched and provide better SNR than any other cable on the market.
  • Pacemaker detection standard
    The conflicting requirements for signal sensitivity (wide bandwidth and high sample rate) and long battery life have been uniquely resolved to provide highly accurate diagnostic information.
  • Foreign language interfaces
    Multiple foreign languages are programmed into each unit to suit diverse patient populations. Currently support Danish, English, Finnish, French, German, Italian, Polish, Portuguese, Spanish and Turkish.
  • Industry-leading 3-year warranty
    These units are built-to-last. Our field return rate is proven to be so low that we can offer the industry’s longest warranty -- and then extend that to 5 or more years to add even more value to your investment.
  • Cable options
    May be used with Oxymetry (oxy plus 5-lead), 5-lead, or 7-lead or 12-lead cables.
  • Maximize good quality recording cycles
    Checks battery state, lead hook-up quality, date and patient ID on LCD prior to deployment. No mix-ups with patient data because patient ID is encoded on memory card.
  • All digital recording
    Reliable digital technology is used throughout, enhancing service life and lowering total cost of ownership.
  • Pediatric (high sensitivity mode)
    High resolution modes can be selected for pediatric patients.
