Atria were not included in flow calculations. All flow values derived from mean of 2 simultaneously injected IDMIs, expect as noted. Cardiac output is per kilogram body weight; myocardial flows, F′, are per gram myocardium, LV, left ventricle; RV, right ventricle; A, atrium; ${\mathrm{F}}_{\text{LV}}^{\prime }$ and ${\mathrm{F}}_{\text{RV}}^{\prime }$, average left and right ventricular blood flow, respectively; ${\mathrm{F}}_H^{\prime }$, average myocardial blood flow.

^*Only one IDMI tracer was used in this experiment.
