Correlation of Intrathoracic Impedance Measures With Blood Plasma Volume in Congestive Heart Failure

NCT00603213 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 25

Summary

Congestive heart failure is a condition in which the heart is weakened and is unable to pump enough blood to the organs of the body to meet the demands of the body. At times there may be a buildup of fluid in the lungs, legs or other parts of the body. The accumulation of this fluid has been shown to affect the resistance to flow of the electrical impulses generated in the heart. The purpose of this study is to correlate measurements to the passive flow of electricity generated by the heart within the chest (as measured by the Optivol TFS System) with measurements of the volume of blood in the body.

Conditions

  • Congestive Heart Failure

Interventions

PROCEDURE

Blood Volume Analysis, Echocardiogram

Blood Volume Analysis: The use of radioactive tracer to determine plasma volume and red cell mass. Echocardiogram is an ultrasound of the heart.
