Ouabain-induced negative frequency-force relationship in the isolated, blood-perfused dog atrium.
Effects of ouabain, CaCl2 and verapamil on the frequency-force relationship (FFR) were investigated in the isolated, blood-perfused dog atrial muscle preparation. When ouabain (3 and 10 micrograms) or CaCl2 (0.5, 1 and 2 mg/min) was given into the sinus node artery, the contractile force of the atrial muscle, driven at a constant pacing rate of 2 Hz, increased dose-dependently. Verapamil (1 and...
متن کامل"Fade" of hyperpolarizing responses to vagal stimulation at the sinoatrial and atrioventricular nodes of the rabbit heart.
Previous studies have suggested that maintained vagal stimulation or acetylcholine infusion results in a fade of responses in the sinoatrial node but not in the atrioventricular node, implying different muscarinic receptor subtypes in the two regions. We investigated this hypothesis in 23 isolated rabbit atrial preparations made quiescent by continuous superfusion with verapamil (1 microgram/ml...
متن کاملSuppression of strychnine on the chronotropic and inotropic effects in the isolated, blood-perfused canine atrium.
In the isolated, blood-perfused dog atrium, strychnine evoked dose-dependent decreases in atrial rate and contractile force, and the negative cardiac effects were not influenced by atropine. Strychnine suppressed dose-dependently the negative chronotropic and inotropic responses to intramural parasympathetic nerve stimulation, but not the response to acetylcholine. These results suggest that st...
متن کاملPotent vasoconstrictor responses to endogenous digitalis-like factor of isolated, perfused dog intermediate auricular arteries.
Endogenous digitalis-like factor obtained from urine of hypertensive patients caused a vasoconstriction in a dose-related manner in isolated, perfused dog intermediate auricular arteries. The constriction was not modified by alpha-adrenoceptor blockade.
متن کاملCardiovascular effects of dibutyryl cyclic AMP in the intact dog heart and the isolated cross-perfused right atrium.
This study used an isolated right atrial preparation, cross-perfused with arterial blood from a support dog. We investigated the effects of dibutyryl cyclic AMP (DBcAMP) on heart rate and arterial blood pressure of the support dog and on the sinus rate and atrial contractile force of the isolated perfused atrium. DBcAMP was injected into the external jugular vein of the support dog or into the ...
