1·Current ablation procedures, which use high-energy radio waves to treat certain types of serious arrhythmias, have only 50-60 percent long-term success.
现有的消融操作，采用高能射频波来治疗特定类型的严重心律失常，长期治愈率只有50 - 60%。
2·Lidocaine is generally ineffective in preventing ventricular arrhythmias, as is cardiac pacing or atropine to increase the heart rate.
利多卡因一般在预防室性心律失常是无效的，就像心脏起搏或阿托品对心率增加没有帮助一样。
3·These effects are of considerable importance in the genesis of a number of important arrhythmias.
这些效应在某些重要的心律失常的发生上有相当重要的意义。
4·The epinephrine dose causing arrhythmias with sevoflurane was comparable to that with isoflurane, but larger than that with halothane or enflurane.
七氟醚麻醉下引起心律失常的肾上腺素剂量与异氟醚相似，但大大高于氟烷或安氟醚。
5·Objective To evaluate and synthesize evidence regarding optimal use of amiodarone for various arrhythmias.
目的：评估和总结胺碘酮对各种心律失常的最适使用证据。
