摘　　要：Cardiac ablation is an important modality of invasive therapy in modem cardiology, especially in the treatment of arrhythmias, as well as other diseases such as hypertrophic obstructive cardiomyopathy （HOCM）. Since Huang et alI used radiofrequency （RF） to ablate canine atrial ventricular junction, RF has developed into the leading energy source in catheter ablation of arrhythmias. However, there are several limitations associated with RF ablation, one of which is that it requires good contact and the depth of the lesion formed is usually limited. Thus, it is often very difficult to ablate arrhythmias originated at the epicardium with a routine endocardial RF delivery.Cardiac ablation is an important modality of invasive therapy in modem cardiology, especially in the treatment of arrhythmias, as well as other diseases such as hypertrophic obstructive cardiomyopathy （HOCM）.
