Radio-potassium indicator-dilution studies during angiocardiography.
In an attempt to learn more about the physiologic changes in the cardiovascular system during angiocardiography and the nature of mixing of radio-opaque dyes with blood, radiopotassium and Diodrast I' dilution curves were obtained before and during angiocardiography. Studies in patients without valvular disease and with mitral valvular disease indicated an increased cardiac output during angioc...
متن کاملIndicator-dilution studies with "diffusible" indicators.
• The indicator-dilution principle has been applied to studies of the circulation in order to provide estimates of flows and volumes in the vascular compartment. A sine qua non of validity of these estimates is that the indicator used remain within the confines of: the vascular compartment for the entire duration of the period required to obtain appropriate samples of blood. In such a symposium...
متن کاملThe two-catheter technique in indicator-dilution cardiovascular studies.
Indicator dilution technique is more widely used during cardiac catheterization for the diagnosis and rough estimate of the size of intracardiac shunts and valvular regurgitation (Korner and Shillingford, 1955; Fox and Wood, 1957; Swan and Wood, 1957; Woodward et al., 1957; Shillingford, 1958; Carter et al., 1959; Carleton et al., 1960; Jose et al., 1960). Evans blue dye (T-1824) has long been ...

متن کاملThe electrocardiogram during angiocardiography.
It is often said that angiocardiography carries little risk, and series of more than a thousand injections without a death are on record (Sussman, 1948; Horger et al., 1951). During recent years, however, more than thirty deaths have been reported-the majority in children with cyanotic congenital heart disease. The exact cause of these deaths has still to be discovered. When Mr. R. C. Brock beg...
