  • Look Inside

To assess the reliability of right ventricular ejection fraction (RVEF) during exercise measured by ther-modilution technique using a modified Swan-Gantz catheter with a fast-response thermister, we measured RVEF under several conditions in 19 patients with cardiac disease. Measurements were repeated 5 times in each condition, and average RVEF and coefficient of variation (CV) were evaluated. 1) Injectate volume did not affect RVEF and CV. 2) A reduction in RVEF occured with the thermister moved from proximal portion to distal portion within the pulmonary artery.
