Abstract：
BACKGROUND: The proportion of abnormal electrocardiogra (ECG) in patients with coronary artery fistula (CAF) is relatively high, but the correlation between CAF and arrhythmia is mostly reported in individual case studies. This paper analyzes the correlation between imaging features and ECG features.
OBJECTIVE: This paper aims to analyze the incidence and distribution characteristics of abnormal ECG in patients with CAF and further explore the difference in ECG characteristics between coronary-cameral fistula (CCF) and coronary-pulmonary artery fistula (CPAF).
METHODS: A total of 144,448 patients who underwent coronary computerized tomography angiography (CTA) examination from January 2016 to December 2022 were included in this study, and 284 patients with CAF (excluding coronary atherosclerosis) were selected for analysis of their ECG and image characteristics. And divided them into the CPAF (221 cases) and CCF (63 cases) groups, the differences in ECG between the two groups was compared. The changes in the ECG after the operation were analyzed.
RESULTS: The incidence of abnormal ECG in patients with CAF was approximately 72.9%. There were significant differences in the proportion of ECG block, myocardial ischemia and structural ECG changes between the CPAF group and CCF group (P < 0.05). CCF was more likely to cause conduction block and ischemic and structural ECG changes. A total of 53 patients with CAF underwent surgical treatment, 28 patients with improved ECG (52%).
CONCLUSIONS: CCF especially CCF patients often have abnormal ECG findings such as conduction block, myocardial ischemia, and structural changes, which can often be restored to normal through surgery.

摘要：
背景：冠状动脉瘘（CAF）患者中异常心电图（ECG）的比例相对较高，但CAF与心律失常之间的相关性主要是在个例研究中报道的。本文分析了影像学特征与心电特征之间的相关性。
目的：分析CAF患者心电图异常的发生率及分布特点，进一步探讨冠状动脉冠状动脉瘘(CCF)与冠状动脉肺动脉瘘(CPAF)心电图特征的差异。
方法：将2016年1月至2022年12月接受冠状动脉CT血管造影（CTA）检查的144,448例患者纳入本研究。选择284例CAF患者（不包括冠状动脉粥样硬化）进行心电图和图像特征分析。并将其分为CPAF组(221例)和CCF组(63例),比较两组心电图的差异。分析术后心电图的变化。
结果：CAF患者心电图异常的发生率约为72.9%。心电图阻滞的比例存在显著差异,CPAF组与CCF组的心肌缺血和心电图结构改变(P<0.05)。CCF更容易引起传导阻滞以及缺血性和结构性ECG改变。共有53例CAF患者接受了手术治疗，28例患者改良心电图(52%)。
结论：CCF尤其是CCF患者常有异常的心电图表现，如传导阻滞，心肌缺血,和结构变化，通常可以通过手术恢复正常。
