ATTENUATION AND RECOVERY OF EKG-T-WAVE IN HOSTILE AND NON-HOSTILE SUBJECTS

本研究的目的是评估不同的副交感神经 对敌对/A型（冠状动脉- 倾向）和非敌对/B型（非冠状动脉倾向）个体。 我们 先前的工作已经表明，较大的β受体介导的电生理 对异丙肾上腺素输注的反应 我们 假设这种效应是由于迷走神经保护不足所致。 心室肌对抗敌对型交感神经效应的研究 A

The purpose of this study is to evaluate differences in parasympathetic effects on adrenergic receptor function between hostile/Type A (coronary- prone) and nonhostile/Type B (noncoronary-prone) individuals. Our previous work has shown larger beta receptor-mediated electrophysiologic responses to isoproterenol infusion among hostile Type A's. We hypothesize that this effect is due to deficient vagal protection of the ventricular myocardium against sympathetic effects among hostile Type A's.
