Use of Multi-site Near Infrared Spectroscopy (NIRS) Monitoring for Hemodynamic Assessment During Tilt Table Testing in Children

PURPOSE OF THE STUDY

This study will explore the use of multi-site NIRS monitoring during tilt table testing, combining somatic and cerebral saturations data with hemodynamic data to establish the non-invasive assessment of global cardiac output distribution trends.

HYPOTHESIS / SPECIFIC AIMS

Study Aims: To evaluate the utility of multi-site NIRS monitoring in the cardiovascular hemodynamic assessment of children and adolescents during tilt table testing by establishing a non-invasive method to predict cardiac output maldistribution with the use of two-site NIRS monitoring in children and adolescents with syncope.
