Is action potential duration of the intact dog heart related to contractility or stimulus rate?

1. The contractility (maximum rate of rise of left ventricular pressure) and action potential duration were measured in intact closed-chest anaesthetized dogs with complete atrioventricular dissociation and β-adrenergic blockade. 2. Measurements were confined to test beats following a 1 sec interva...
