The right ventricular ejection pattern is characterized by early onset, gradual rise to peak flow velocities in midsystole and gradual return to baseline. Left ventricular ejection begins very shortly after right ventricular systole, abruptly reaches

Radiotelemetry was used to study regional blood flow distribution in Alaska sled dogs during cross-country runs. Doppler ultrasonic flowmeter transducers were chronically implanted on the coronary, renal, and mesenteric arteries, terminal abdominal a

The microscopic appearance of small arterioles during epinephrine-induced vasoconstriction was studied in the dog mesentery. The tissues were quick-frozen in situ with liquid isopentane, freeze-substituted, and sectioned serially. Obliteration of the

Left ventricular pressure and diameter and aortic blood flow were recorded during asystole in ambulatory dogs with chronic complete heart block. Asystole occurred spontaneously, or was induced by acetylstrophanthidin or pacemaker withdrawal, and was

The effects of stimulating the carotid sinus nerves on the distribution of cardiac output and peripheral vasoactivity was studied in intact, unanesthetized dogs instrumented with ultrasonic or electromagnetic flow probes on the ascending aorta, mesen

The first step in analyzing any clinical problem must be the identification and precise definition of the entity. An adequate definition must be based on accurate and quantitative description in terms of crucial variables. Since many of the essential

A description in standard physical terminology of the variations of the left ventricle in its role as a pump was derived. Left ventricular pressure, left ventricular outflow, and an external dimension of the left ventricle were measured in unanesthet

The cytoarchitectural changes which take place in the walls of small arteries (about 1 mm. O.D.) during vasoconstriction and vasodilation have been studied. Vessels were fixed while in their functional state by immersion in liquid isopentane at -170
