abstract：:Changes in left ventricular internal diameter resulting from increasing intrapericardial pressure induced by increasing the pericardial fluid volume were studied in closed chest, anaesthetized dogs. Left ventricular internal diameters were measured by placing an ultrasonic dimension catheter in the left ventricle at t...

abstract：:The effect of lidocaine on the effective refractory period of the right ventricle (EVRP) was measured in 10 patients using the extra stimulus technique of progressive introduction of premature stimuli until a response could not be elicited. In four patients lidocaine produced a significant decrease in the EVRP, in a f...

abstract：:Pressure--diameter loops were generated in normal, conscious dogs during left ventricular contraction by means of endocardial ultrasonic gauges and micromanometers. Studies were made in the control state, during volume and pressure loading, and during enhancement of contractility. The diameter at the end of ejection w...

abstract：:The effect of axial rotation on flow through and pressure gradient across saphenous vein segments was studied using 15 cadaver long saphenous veins. A significant reduction in flow occurred at a mean rotation of 25 degrees/cm and a significant increase in head loss across the segments occurred at a mean rotation of 23...

abstract：:The effect of digoxin, at two different inotropic levels, was examined in normo- and hyperkalaemic dogs. For similar inotropic responses, normo- and hyperkalaemic dogs had similar levels of (Na+, K+)-ATPase inhibition and microsomal-bound digoxin. ...

abstract：:Postextrasystolic potentiation was studied by means of a catheter-tip manometer in patients with and without cardiomyopathy. The results imply that the enhancement of the left ventricular contraction is increased in patients with cardiomyopathy. ...

abstract：:Systemic haemodynamics and regional myocardial blood flow responses to hypertonic mannitol were studied in 10 conscious and 23 anaesthetized dogs. Mannitol infusion significantly increased regional myocardial blood flow in the conscious, intact dogs. Mannitol increased total coronary flow 20% in anasethetized animals ...
