对造成心率、心律与传导障碍的电生理机理的研究,以及对抗心律失常等药物的作用与作用机理的研究,使之能发展出一个看来是合理的心律失常治疗途径。某些从心脏电生理学所得出的法则具有普遍的适用性,另一些则看来还需进一步验证。在预期和实际效果之间尚存在很多矛盾,这些矛盾的发生具有很多因素。很可能人类的心脏病变可对心脏细胞的电活动产生影响,而这些影响尚未在实验动物中复制出来。也可能疾病通过某些尚未被发现的方式改变了心脏细胞对药物的反应。尽管如此,已经取得了一些进展;进一步的实验和设想,有可能提供更清晰的见解,以及更新、更好的治疗药物。 Studies on the electrophysiological mechanisms that cause heart rate, heart rate, and conduction disturbances, as well as the effects and mechanisms of action against drugs such as arrhythmias, have led to the development of a seemingly rational approach to the treatment of arrhythmias. Some of the rules derived from cardiac electrophysiology have universal applicability, while others appear to require further validation. There are still many contradictions between expected and actual results, and there are many factors in the occurrence of these contradictions. It is likely that human heart disease can have an impact on the electrical activity of heart cells and that these effects have not yet been replicated in laboratory animals. It is also possible that the disease changes the response of the heart cells to the drug in some way that has not yet been found. In spite of this, some progress has been made; further experiments and ideas are likely to provide clearer insights as well as newer and better therapies.
