Reflex Diuresis during Tachycardia in the Dog

Reflex Diuresis during Tachycardia in the Dog

Renal function and systemic hemodynamics were studied during rapid atrial pacing in dogs with complete heart block and in control dogs with normal atrioventricular conduction. Rapid atrial pacing in dogs with complete heart block produced no significant change in urine flow, sodium excretion, or systemic hemodynamics. In contrast, rapid cardiac pacing in control dogs produced progressive increa...

Reflex tachycardia due to temporary coronary occlusion in the conscious dog.

Reflex increases in heart rate which occurred during 1-minute occlusions of the left circumflex coronary artery were studied in conscious dogs. The results indicated that occlusion produced tachycardia (latency to onset 8.5 seconds) preceded by a rise in left atrial pressure (7.2 seconds) and followed by a small fall in arterial pressure (19.5 seconds). Bilateral baroreceptor denervation indica...

Acute effects of the administration of vasopressin during water diuresis in the dog.

The oculorespiratory cardiac reflex in the dog.

Intraorbital and intracranial electrical stimulation as compared with manual eye pressure indicates that in the dog the afferent pathway for the oculorespiratory cardiac reflex is carried by the ophthalmic division of the fifth cranial nerve. The effects on cardiac and respiratory arrythmia produced by using intravenous atropine have demonstrated that, although reflex bradycardia can be abolish...

Renal Water Reabsorption during Saline and Urea Osmotic Diuresis in the Dog.

MAUIDE, DAVID L., AND LAURENCE G. WESSON, JR. Renal wuter reabsorption during saline and urea osmotic diuresis in the dog. Am. J. Physiol. 205 (3) : 477-482. rg63.-Free water reabsorption (TWC) was measured in conscious dogs during a longterm, reasonably steady-state osmotic diuresis induced either by sodium salts or by urea. After 4 to 8 hr the original solute was partially replaced by urea or...
