本研究通过减少50%的冠状动脉血流90分钟,观察72小时的心脏电生理和心肌血流局部分布的改变,还评价交感神经系统对观察到的电生理效应和室性异位活动的影响。
This study also evaluated the effects of the sympathetic nervous system on observed electrophysiological effects and ventricular ectopic activity by observing changes in cardiac electrophysiology and local distribution of myocardial blood flow for 72 hours by reducing coronary blood flow by 50% for 90 minutes.
