A basket shaped catheter carrying 64 electrodes was developed in the left ventricle (LV) of 53 pigs which had undergone induction of myocardial infarction. Pacing during sinus rhythm, or echocardiographic and hemodynamic measurements as well as pathological studies revealed no significant damage due to the basket catheter. Eighty one episodes of ventricular tachycardia (VT) were mapped and analyzed, requiring only several beats and less than 10 seconds to complete. We were able to successfully ablate ventricular tachycardias in four pigs.
在53只已诱发心肌梗死的猪的左心室（LV）中，研制了一种携带64个电极的篮状导管。在窦性心律起搏期间，或进行超声心动图和血流动力学测量以及病理研究，结果显示篮状导管未造成明显损伤。对81次室性心动过速（VT）发作进行了标测和分析，完成这些只需几个心搏且耗时不到10秒。我们成功地对4只猪的室性心动过速进行了消融。
