[Coronary blood flow during stochastic stimulation of the canine heart].
Changes of mechanical activity and coronary blood flow induced by haphazard uncorrelated sequence of stimuli, were studied in the dog heart. The total coronary blood flow did not differ from one during determined regimen of the same mean frequency. Whereas relative contribution of systolic coronary flow increased and that of diastolic one decreased. The analysis of phasic blood flow in coronary vessels during potentiated and extrasystolic contractions, was performed.
