在使用最新一代抗心律失常药之前,病人需了解除药物对脉搏的作用以外更多的知识。通常情况下,病人不需要知道有关药理的成份。然而,他们确实需要知道抗心律失常药物是怎样控制其特殊的心脏病的。除了用日常知识比拟了解外,我们也使用一些简单的心脏方面的图表来帮助他们了解心脏是怎样工作的,正常心脏的传导系统和怎样增强心脏的自律性.以及因节律障碍而产生的折返型心律失常的原因。抗心律失常药物根据它们对心脏动作电位的效应分类,这种效应是跨膜电位产生的一系列变化。它作用于心肌活动主要是通过改变心肌传导性、改变有效不应期和自律性三种方式。
Before using the latest generation of antiarrhythmic drugs, patients need to learn more about the effects of drugs on pulse. Often, patients do not need to know about pharmacological ingredients. However, they really need to know how antiarrhythmic drugs control their particular heart disease. In addition to using everyday knowledge to compare and understand, we also use some simple chart of the heart to help them understand how the heart works, the normal heart conduction system and how to enhance the heart’s self-discipline, as well as due to rhythm disorders and reentry Causes of arrhythmia. Antiarrhythmic drugs are categorized according to their effect on cardiac action potentials, a series of changes that result from the transmembrane potential. It acts on myocardial activity is mainly through the change of myocardial conductivity, change the effective refractory period and self-discipline in three ways.
