Abstract

The effects of angiotensin II on sinus rate and atrial contractility were investigated in 17 isolated canine atria and 5 isolated paced ventricular preparations perfused with arterial blood conducted from a heparinized donor dog. When angiotensin II was injected into the cannulated sinus node artery, positive chronotropic responses were dose-dependently produced starting from the 0.01 microgram dose although inotropic responses to angiotensin II were not consistently induced. Angiotensin II produced a similar inotropic response pattern in the paced ventricular preparation. Moreover, when angiotensin II was given into the jugular vein of the donor dog, similar positive chronotropic and inotropic responses were also shown in the isolated atrium. Angiotensin II-induced positive chronotropic and slight inotropic effects were not influenced by treatment with the beta-adrenoceptor blocking agents, propranolol and carteolol, but significantly suppressed by saralasin which has been reported to be a competitive antagonist of angiotensin II. From these results, it is suggested that angiotensin II induced a positive chronotropic and slight positive inotropic effect via angiotensin II receptors in the dog heart.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
