Effect of brief ultrasound exposure on post-tetanic potentiation in cardiac muscle
The effect of a short 4 second ultrasound application (1.0 W/cm2 SATA at 963 KHz) on the post-tetanic-potentiation of isolated isometrically contracting rat papillary muscle has been evaluated. Post tetanic-poten...

Interval dependent inotropic effects in the rat myocardium and the effect of calcium
Peak isometric tension was measured in isolated rat papillary muscles at different external calcium levels. Rested state contraction (RSC) tension follows a sigmoid curve when plotted against external calcium ...
