Catechol-mediated effects of harmaline on the action potential of rat atrial fibres
(Oxford University Press, 1977)
Summary: The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the ...
Cardiomyopathies produced by toxoplasma gondii
(1968)
Eleven cases of cardiomyopathy are presented in which the toxoplasmic infection was ascertained by serologic study. The parasite was recovered from the heart in one of them. All other common etiologies were ruled out by ...
Catechol mediated effects of harmaline on the action potential of rat atrial fibres
(1977)
The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the slow ...
Total and regional coronary blood flow during acute right ventricular pressure overload
(Oxford University Press, 1974)
AUTHORS' SYNOPSIS: Total and regional coronary blood flow were measured with radioactive microspheres before and during acute right ventricular pressure overload. Coronary flow to the left ventricular wall decreased and ...
Mechanical effects of heart contraction on coronary flow
(Oxford University Press, 1975)
AUTHORS' SYNOPSIS: The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing ...
Total and regional coronary blood flow during acute coronary occlusion in anaesthetized and conscious dogs
(Oxford University Press, 1974)
Total and regional coronary blood flow was measured with radioactive microspheres before and early after the occlusion of the anterior descending coronary artery. A radial gradient of flow was found in the ' infarcted' ...
Effect of heart rate on regional coronary blood flow
(1976)
The effect of tachycardia on the distribution of coronary blood flow was studied in the dog heart using the radioactive microsphere technique. Increasing heart rate from 1.7 to 3.0 Hz produced an increment of flow to the ...
