The fields of noninvasive cardiac imaging and clinical cardiac electrophysiology have both benefited from improved technology and techniques in recent years. Evidence is growing that improved noninvasive imaging techniques may shorten procedure times and improve procedural success rates. Because this application of noninvasive imaging represents an emerging area of interest, robust clinical trial data about the effect of cardiac computed tomography (CT) on clinical endpoints is lacking. This article reviews the available evidence in this area and highlights current and future directions of inquiry. Applications of CT in clinical cardiac electrophysiology currently relate to atrial fibrillation ablation techniques, image integration with electroanatomical mapping systems, biventricular lead insertion for cardiac resynchronization therapy, and evaluation of arrhythmogenic substrates.
近年来，无创心脏成像和临床心脏电生理学领域均受益于技术和方法的改进。越来越多的证据表明，改进的无创成像技术可能会缩短手术时间并提高手术成功率。由于无创成像的这种应用代表了一个新兴的研究领域，因此缺乏关于心脏计算机断层扫描（CT）对临床终点影响的强有力的临床试验数据。本文回顾了该领域的现有证据，并强调了当前和未来的研究方向。CT在临床心脏电生理学中的应用目前涉及心房颤动消融技术、与电解剖标测系统的图像整合、用于心脏再同步治疗的双心室导线植入以及致心律失常基质的评估。
