Comparative cardiac electrophysiologic study of PK 10139, a new antiarrhythmic agent, and quinidine in anesthetized dogs: plasma concentration-response relationships.

abstract：:During the last few years, there has been a growing awareness that treated hypertensive patients are still at substantially increased risks for cardiovascular morbidity and mortality and that one conceivable explanation for this is that their blood pressure has not been lowered to strictly normotensive levels. To obta...
