摘 要: | 本文系统介绍关于心肌梗塞时植物神经系统作用方面的研究进展。心肌梗塞时交感一儿茶酚胺活性增高,副交感神经兴奋性也同时提高。前者可使梗塞范围扩大,心室功能下降加剧及心律失常发生率增加,而后者对心肌梗塞具有保护作用。文中详细叙述上述作用的病理生理机制,并联系说明临床使用β阻滞剂及阿托品的原理及其原则。此外,心室壁感受器反射是心肌梗塞发生时机体的一种保护性机制。

The Role of Autonomic Nervous System in Myocardial Infarcfion and It's Clinic Significance |
| |
Abstract: | The developement of recent researches about the role of autonomic nervous system in myocardial infarction (MI) was summed up Systematically. In case of MI there is a raise of cardiac Sympathetic-catecholamine activity and the parasympathetic exitibility also goes up. The former may extend the MI size,aggravate the cardiac function and increase the rate of arrythmia, while the later plays a protective role in MI.Their mechanisms were synthesized in detail and the clinic application of β-adrenergic receptor blocked and atropine in MI was mentioned. In addition, the enhancement of reflex elicited from ventricular receptors may be a protective mechanism in MI. |
