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。

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。
