Full Autonomic 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. 

• 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
• Head–up tilt analysis (requires optional tilt table)
• Quantitative sweat measurements of both resting and evoked sweat potential
