WR Medical - Full Autonomic Testing Lab

This lab includes the cardiac lab, the Q-Sweat quantitative sweat measurement system, and beat-to-beat blood pressure acquisition for testing of cardiovagal (parasympathetic) function, adrenergic (sympathetic) function, and sudomotor axon reflex function. With the inclusion of the optional WR Tilt Table even more functionality is added, which can be used to create a Composite Autonomic Severity Score (CASS).

All tests are non invasive, standardized, quantitative, and easy to perform. A full autonomic assessment can be performed in as little as one hour per patient.

Tests and analyses available to assist in patient diagnosis include:

• Heart Rate Response to Deep Breathing (HRDB), using ECG or R-R interval
• Valsalva Maneuver, using ECG or R-R interval
• 30:15 Ratio, using ECG or R-R interval
• E:I Ratio
• Baroreflex sensitivity including cardiovagal and adrenergic analyses
• Pressure Recovery Time (PRT) Interval
• Head–up tilt analysis (requires optional tilt table)
• Linear regression analysis support
• Spectrum Analysis support
• Quantitative sweat measurements of both resting and evoked sweat potential

Includes:

• Cardiac Lab (HRV Acquire)
• Q-Sweat Quantitative Sweat Measurement System
