The material on the surface vaporizes and blows away — a process called ablation.

其表面的物质随之蒸发并被吹走——这一过程被称为。

An echo? What about cardioversion or ablation? Won't I need a pacemaker or a permanent internal defibrillator?

超声波检查？干嘛不来个心脏复律射频消融？我难道不需要装一个起搏器永久性的心内除颤仪？

Laser ablation gets around those problems by using short pulses from a handheld laser to dislodge grime.

激消融通过使用手持激发出的短脉冲去除污垢来解决这些问题。

The goal here is ablation, which is a fancy word for removing material from the surface of something.

这里的目标，这一个花哨的词，表示从某物表面去除材料。

This method is called laser ablation, and it was first developed in the 1970s to get something called black crust off marble.

这种方法被称为激，它最初在 20 世纪 70 年代开发的，目的从大理石上去除一种叫做黑色外壳的东西。

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有必要的了。

The low rate of ablation also means that this is great for pushing debris and dust out of the way, almost like a broom.

低率也意味着这非常适合将碎片和灰尘推开，几乎就像扫帚一样。

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。

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，就射频波被用于摧毁导致异位心搏的组织。
