They're usually asymptomatic, but when they're a sign of an underlying disorder, treatment including a radiofrequency ablation may be necessary.

它们通常是无症状的，但当成为潜在疾病的体征时，包括射频消融在内的治疗就可能是有必要的了。

Department head Dr. Philippe Brouqui explains that radiofrequency identification chips, or RFIDs, are placed in soles of hospital shoes, while antennas are placed on the floor.

部门主管菲利普博士解释说，这种射频识别芯片(RFIDs)被放置在医院用鞋的鞋底上，其天线放置在地板上。

If an ectopic focus is triggering atrial fibrillation, radiofrequency ablation can be done, which is where radiofrequency waves are used to destroy the tissue that's causing the ectopic heartbeat.

如果异位起搏点引发了心房颤动，就需要做射频消融了，即利用射频波破坏导致异位心搏的组织。

If an ectopic focus is triggering ventricular arrhythmias, radiofrequency ablation can be done, which is where radiofrequency waves are used to destroy the tissue that's causing the ectopic heartbeat.

如果异位起搏点引发了室性心律失常，可以做射频消融，就是射频波被用于摧毁导致异位心搏的组织。

If they do develop dangerous tachyarrhythmias, however, they may be treated pharmacologically, but a definitive treatment is radiofrequency catheter ablation of the accessory pathway, or Bundle of Kent.

如果他们发展到了危险的快速性心律失常，应该使用药物治疗，长期治疗首选对肯特束（“旁路”）行导管射频消融术。

For initial stages, when the cancer has invaded just the mucosa and submucosa, options include esophagectomy, endoscopic tumor resection, or mucosal ablation - which is when the cancerous mucosa is removed by radiofrequency.

早期肿瘤只入侵黏膜和黏膜下层，治疗选择包括食管切除术、内镜下肿瘤切除术或黏膜消融术，即用射频消融被肿瘤侵袭的黏膜。
