Successful mapping and ablation of ventricular tachycardias remains a challenging clinical task. Whereas conventional entrainment and activation mapping was for many years the gold standard to identify reentrant circuits in ischaemic ventricular tachycardia ablation procedures, substrate mapping has become the cornerstone of ventricular tachycardia ablation. In the last decade, technology has dramatically improved. In parallel to high-density automated mapping, cardiac imaging and image integration tools are increasingly used to assess the structural ventricular tachycardia substrate. The aim of this review is to describe the technologies underlying these new mapping systems and to discuss their possible role in providing new insights into identification and visualization of reentrant tachycardia mechanisms.
成功地对室性心动过速进行标测和消融仍然是一项具有挑战性的临床任务。虽然传统的拖带和激动标测在多年来一直是识别缺血性室速消融程序中折返环的金标准，但基质标测已成为室速消融的基石。在过去的十年中，技术有了显著的进步。除了高密度自动标测外，心脏成像和图像整合工具也越来越多地用于评估结构性室速的基质。本文的目的是描述这些新的标测系统所基于的技术，并讨论它们在提供对折返性心动过速机制的识别和可视化的新见解方面的可能作用。
