Currently, analysis of sustained ventricular tachycardia postmyocardial infarction in man is limited by the time required for single point activation mapping and the difficulty in obtaining information during hemodynamically unstable arrhythmias. To overcome these limitations, we developed a multielectrode "basket" catheter for endocardial recording and pacing. This report describes the first clinical use of such a catheter to guide successful radiofrequency ablation of incessant sustained ventricular tachycardia postmyocardial infarction. This system may significantly shorten the time required for VT analysis and improve the results of radiofrequency catheter ablation for VT postmyocardial infarction.
目前，人类心肌梗死后持续性室性心动过速的分析受到单点激动标测所需时间以及在血流动力学不稳定的心律失常期间获取信息困难的限制。为克服这些限制，我们开发了一种用于心内膜记录和起搏的多电极“篮状”导管。本报告描述了首次临床使用这种导管指导成功射频消融心肌梗死后持续性室性心动过速。该系统可能会显著缩短室性心动过速分析所需时间，并改善心肌梗死后室性心动过速的射频导管消融结果。
