The effects of alterations in the diastolic filling pressure of the right ventricle on left ventricular
(LV) geometry and filling pressure were studied in six isolated, supported canine hearts. …

Subjective estimates of the angiographic severity of coronary artery stenoses show variability
and inaccuracy. We therefore tested the accuracy of a newly developed computerized …

Acute mitral regurgitation (MR) was produced in 12 dogs by closed chest partial valvulectomy
and the relative contributions of MR pressure gradient (MRG), the time for regurgitant flow (…

… In another control group under similar conditions, 16 out of 20 dogs developed ventrieular
fibrillation (Lanari and Serur, 1965). The incidence of ventrieular fibrillation in these 2 groups …

The mechanism whereby respiratory acid-base changes alter myocardial contractility is
poorly understood. Accordingly, 46 cat right ventricular papillary muscles contracting …

Previous studies have shown that with progressive arterial stenosis, resting blood flow does
not start to diminish until 85-95% luminal area stenosis is reached. However, during …

Glucose has been long known as an important substrate for muscle cells and a number of
laboratories have demonstrated that carbohydrate metabolism can contribute significantly to …
