As the population of patients with implanted defibrillators has grown, an increasing number of patients nonischemic cardiomyopathies are requiring therapy to reduce ventricular arrhythmias. Most of these arrhythmias are related to areas of ventricular scar. Although the pathophysiology of scar development is not well understood in these diseases, advances in cardiac imaging and mapping are better characterizing the scar locations that give rise to the arrhythmias. Here, we review the pathophysiologic and electrocardiographic correlations that inform ablation strategies for ventricular tachycardia in these diseases.
随着植入式除颤器患者数量的增加，越来越多的非缺血性心肌病患者需要治疗以减少室性心律失常。这些心律失常大多数与心室瘢痕有关。尽管这些疾病中瘢痕形成的病理生理学尚未得到很好的理解，但心脏成像和映射技术的进步更好地描述了引起心律失常的瘢痕部位。在这里，我们回顾了指导这些疾病中心律失常消融策略的病理生理和心电图相关性。
