Optical Coherence Tomography (OCT) imaging is a valuable tool for complex coronary interventions. While complications are rare, the occurrence of ventricular arrhythmias during its use is one of the most feared. Unfortunately, the mechanism by which these arrhythmias arise remains unclear. We describe the case of a patient under continuous electrocardiographic (ECG) monitoring who experienced ventricular fibrillation during an OCT procedure. A detailed analysis of the ECG event sequence was performed, from the administration of the contrast medium to the onset of ventricular fibrillation. Utilizing the collected data, we examined potential precipitating factors based on the observed alterations in the electrocardiogram. A comprehensive understanding of the mechanisms underlying these arrhythmias is crucial for the development of preventive measures that avoid such incidents in the future.
光学相干断层扫描（OCT）成像对于复杂冠状动脉介入治疗是一种有价值的工具。虽然并发症很少见，但在使用过程中发生室性心律失常是最令人担忧的情况之一。不幸的是，这些心律失常发生的机制仍不清楚。我们描述了一名在连续心电图（ECG）监测下的患者在OCT检查过程中发生心室颤动的病例。从注射造影剂到心室颤动发作，对心电图事件序列进行了详细分析。利用收集到的数据，我们根据观察到的心电图变化检查了潜在的诱发因素。全面了解这些心律失常的潜在机制对于制定预防措施以避免未来发生此类事件至关重要。
