心脏电生理障碍,特别是心律失常,是全世界发病率和死亡率的主要原因。有两个基本的要求,为acromogenesis:一个潜在的基板和触发器。传导速度(CV)改变为心律失常发生提供了关键基础,CV减慢通过减少可能发生折返的长度范围增加了折返性心律失常的概率。在这篇综述中,我们研究了体内和体外测量心脏CV的方法,讨论了CV的潜在决定因素,并讨论了病理变化如何改变CV,可能增加心血管疾病的风险。最后,我们将强调未来的方向,方法来衡量CV和可能的治疗,以恢复正常的CV。
Cardiac electrophysiological disorders, in particular arrhythmias, are a key cause of morbidity and mortality throughout the world. There are two basic requirements for arrhythmogenesis: an underlying substrate and a trigger. Altered conduction velocity (CV) provides a key substrate for arrhythmogenesis, with slowed CV increasing the probability of re-entrant arrhythmias by reducing the length scale over which re-entry can occur. In this review, we examine methods to measure cardiac CV in vivo and ex vivo, discuss underlying determinants of CV, and address how pathological variations alter CV, potentially increasing arrhythmogenic risk. Finally, we will highlight future directions both for methodologies to measure CV and for possible treatments to restore normal CV.
