The negative chronotropic effect of carbamoylcholine on spontaneously beating perfused hearts was conspicuously diminished. While 10–5 mol/l carbamoylcholine invariably produced heart arrest in control rats, the heart rate did not decrease by more than 20% in the toxin-treated rats even when the ...

In mammals, cardiac therapy is chosen based on the desired effect on heart contractibility and HR, vasoconstriction or vasodilatation, or increasing or reducing blood volume. The cornerstone of managing CHF rests on reducing the volume of extracellular fluid and reducing preload through the use of...
METHODS: An analysis of 77 consecutive patients undergoing heart transplantations at our institution between June 1988 and July 1994 was performed to assess the effect of donor age on mortality and morbidity. Recipients were grouped into those receiving hearts from younger donors (aged < 40 years,...
