患者男,18岁,反复发作晕厥,静息12导联心电图见图1。试题内容因患者拒绝ICD治疗,下面哪种抗心律失常药物是给患者的最佳选择?A.胺碘酮;B.倍他乐克;C.奎尼丁;D.心律平;E.美西律;正确答案:C.奎尼丁答案分析从图1容易看出患者的心电图很多导联存在J波,且包括V2导联上的Brugada波。结合患者有反复晕厥的病史,因此,诊断患者为J波综合征并非困难。因心电图J波改变的机制是跨心肌细胞膜的Ito
Male patient, 18 years old, recurrent syncope, resting 12 lead ECG shown in Figure 1. Questions ICD treatment because patients refuse, which of the following anti-arrhythmic drugs is the best choice for patients? A. amiodarone; B betametabolol; C. quinidine; D. heart rate; E.

The mechanism by which the J waves of the electrocardiogram change is across the myocardial cell membrane Ito
