| Abstract(in English) | Coronary flow is almost exclusively diastolic,while it has a significant systolic reverse flow(slosh phenomenon).The present study was performed to evaluate the the effect of a-adrenergic stimulation on the slosh phenomenon.We measured septalcoronary artery blood velocities in 12 anaesthesized open chest mongrel dogs during norepiriephrine infusion before and after blockade of a receptor with phenoxybenzarnine.We found that a-blockade increased the slosh phenomenon by increasing the systolic reverse flow.This indicates that c-stimulation has a beneficial effect on transmural blood distribution by reducing the slosh phenomenon. |
