Autonomic Function Testing: Practical Insights

Autonomic Function Testing: Practical Insights is a clinically focused guide to the assessment, interpretation, and practical application of autonomic nervous system testing in cardiovascular and systemic disease. Designed for modern clinical practice, this book translates complex autonomic physiology into clear diagnostic frameworks that support real-world patient evaluation and decision-making. Covering the full spectrum of autonomic function testing (AFT), this volume provides step-by-step guidance on cardiovagal, adrenergic, sudomotor, and tilt-table testing, integrating physiological principles with practical bedside application. Emphasis is placed on understanding normal and abnormal autonomic responses, recognizing diagnostic patterns, and applying test findings within broader clinical contexts. Key topics include: Fundamentals of autonomic nervous system physiology, including sympathetic and parasympathetic regulation Cardiovagal testing, including deep breathing tests, Valsalva maneuver, and heart rate response to standing Adrenergic function assessment, with evaluation of orthostatic blood pressure responses and autonomic cardiovascular regulation Sudomotor testing techniques, including QSART, thermoregulatory sweat testing, and sympathetic skin response Tilt-table testing protocols and interpretation, including differentiation of vasovagal syncope, autonomic failure, and orthostatic syndromes Continuous and ambulatory autonomic monitoring, including heart rate variability and baroreflex sensitivity testing Clinical applications in heart failure, diabetes, syncope, hypertension, and neurodegenerative disorders The book emphasizes structured interpretation and practical troubleshooting, helping clinicians navigate common challenges such as artifacts, inconclusive findings, and patient-related limitations. Real-world clinical scenarios and diagnostic frameworks support accurate interpretation and reproducible testing strategies.
