The results obtained indicate that adenosine may stimulate cardiac sympathetic afferents through adenosine Al-receptor, thereby resulting in the activation of PGL neurons.
目的探讨左心交感神经切除术（LCSD）降低长QT综合征（LQTS）患者心脏事件发生率的机制。
Objective To explore the mechanism of the left cardiac sympathetic denervation (LCSD) surgery to reduce the incidence of cardiac events for long QT syndrome (LQTS) patients.
