Quality Systems. Trusted Results.

The HRV Acquire is used in research labs and clinics along with WR TestWorks to support autonomic testing with clinical evaluation of physiologic parameters.

The new HRV Acquire cardiac testing lab provides support in the testing and evaluation of patients in the areas of cardiovagal function. With the addition of an optional beat-to-beat continuous blood pressure monitor, the system provides adrenergic information, and several other valuable tests are then available for analysis.

Tests and Analyses available:

  • Heart rate response to deep breathing (HRDB), using either ECG or R-R interval
  • Valsalva Maneuver, using either ECG or R-R interval
  • Head-up Tilt (Requires optional Tilt Table)
  • E:I Ratio

Cardiovagal and Adrenergic Analysis (BRS_A1 Method)Included are the all new HRV Acquire, testing computer, software, cart, medical grade power isolation transformer, and all necessary connective hardware. The HRV Acquire combines an ECG, patient cue, manometer, chest expansion bellows, and beat to beat blood pressure inputs all in a single, easy to use device. Comparative reference ranges are included in the WR TestWorks software.

Build the foundation for your Autonomic Testing Lab

Heart Rate Variation is a measure of Cardiovagal (Parasympathetic) Function.

  • Two commonly used and simple measures of HRV:
    • HRDB (Heart Rate Response to Deep Breathing)
    • Valsalva Ratio
  • It provides cost effective, easy-to-perform, and time efficient measurements.
  • Patient testing can be completed in as little as 15 minutes.
  • Testing is non-invasive, standardized, and easy to perform for both patient and technician.
  • Add the WR Tilt Table, Q-Sweat, Beat-to-Beat BP or CASE IV for increased functionality.
  • All labs include on-site installation within the United States and Canada.


  • Autonomic neuropathy is a serious and common complication of diabetes. In randomly selected cohorts of asymptomatic individuals with diabetes, ~20% had abnormal cardiovascular autonomic function. Regular HRV testing provides early detection and promotes timely diagnostic and therapeutic interventions.
  • Reduced heart rate variation is the earliest indicator of cardiovascular autonomic neuropathy.
  • Mortality is associated with diabetic neuropathy. Fifty percent of those with abnormal tests and autonomic symptoms died within 2.5 years, those with the most abnormal tests having the highest mortality.
  • It has been recommended that testing of diabetic individuals for cardiovascular autonomic dysfunction should be part of their standard of care.
