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

本研究的目的是评价副交感神经功能的差异。 敌对/A型之间对肾上腺素能受体功能的影响 (倾向于)和非敌意/B型(不倾向于冠状动脉)的个人。我们的 先前的研究表明，更大的β受体介导的电生理 敌意A型患者对异丙肾上腺素输注的反应。 假设这种效应是由于迷走神经保护不足所致 敌对类型患者的心室肌对抗交感神经效应 A的。

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.
