Cardiac Function as Measured by Non-invasive Electrical Velocimetry Cardiac Monitor in Hospitalized Children
Cardiac Function as Measured by Non-invasive Electrical Velocimetry Cardiac Monitor in Hospitalized Children
To assess whether a non-invasive cardiac output monitor can follow heart function in children
 during treatments in the hospital. To establish a normal reference for children who are well
 and awake.
The aim of the study is to evaluate the ability of a new FDA-approved non-invasive Electrical
 Velocimetry (EV) cardiac monitor called AESCULON (Cardiotronic Inc, La Jolla CA) to detect
 and trend hemodynamic changes in hospitalized ambulatory pediatric patients during recovery
 from acute illness. We postulate that if the cardiac monitor can trend hemodynamic changes in
 hypertensive patients whose mean arterial pressure (MAP) decreases to normal levels, or
 hypotensive patients whose MAP increases to normal levels over several days, it may improve
 our understanding of different disease processes and allow us to improve care. We also seek
 to establish normative data for different measures provided by the AESCULON monitor -
 specifically cardiac output (CO) and systemic vascular resistance (SVR), which are the prime
 determinants of MAP.

 Children with diagnosis of a single chronic medical disorder that is not associated
 with cardiac dysfunction

 Exclusion Criteria:

 -  Congenital heart disease with and without repair (includes PFO, ASD and PDA, cardiac
 valve disease or pulmonary hypertension
