Improved Patient Outcomes by Normalizing Sympathovagal Balance: Midodrine and Parasympathetic and Sympathetic Monitoring
Author(s): Nicholas L DePace, Aaron I Vinik, Cesar R Acosta, Jeysel M Pinales, Michael Yayac and Joseph Colombo*
A function of the Parasympathetic and Sympathetic (P&S) nervous systems is to maintain proper tissue perfusion, including of the heart and brain upon head-up postural change standing. Orthostatic dysfunction (OD) is associated with pooling of blood in the lower extremities, insufficient vascular support of the heart, and poor brain perfusion. Abnormal P&S responses to standing help to guide therapy for the individual patient. Midodrine is often the primary recommendation to correct P&S dysfunction upon standing. P&S Monitoring (Physio PS, Inc, Atlanta, GA) differentiates OD-subtypes in 2727 cardiology patients, serially tested. P&S Monitoring non-invasively, independently, and simultaneously measures P&S activity, including the normal P-decrease followed by an S-increase with head-up postural change (standing). S-Withdrawal (SW) and P-Excess (PE) are two types .. Read More»
