参考答案: 在LC 串联回路中,当串联回路两端的电源频率使得电感元件的 XL与电容元件的 XC 在幅值上相等时,两种元件两端的电压之和为零;对于外部电路而言等同于短路,阻抗等同于 0,这种现象称为 LC 串联电路的谐振现象。 复制 纠错举一反三 多尿是24小时尿量超过于()ml A. 1000 B. 2000 C. 2500 D. ...
房颤 机制复杂,除最常见的肺静脉触发灶外, 还存在诸如 左心耳,上腔静脉,marshall韧 带等肺 外触发灶.尤其对于持续性房颤,常规 PVI联 合 其他辅助消融的个体化消融策略可能会改善预后; 例如,BELIEF 研究中[30] PVI附 加左心耳隔离显 著提 高持续性房颤成功率 (76% vs56%,P = 0.003).同样,术者熟练程度...
