Swan-Ganz catheterization was performed because of persistent unexplained tachycardia in a patient with myocardial infarction. Although there was no premonitory arrhythmia, ventricular tachycardia developed as the catheter was removed. Direct-current cardioversion was required. The occurrence of ventricular tachycardia requiring cardioversion in a patient who experienced no ventricular ectopy earlier in his hospitalization shows that Swan-Ganz catheter removal may provoke potentially serious arrhythmia. Uninterrupted vigilance from the time the Swan-Ganz catheter is inserted to the time it is removed is essential. Therefore, we recommend that the catheter be removed under ECG monitoring by experienced personnel, with lidocaine and a defibrillator available.
一名心肌梗死患者因持续存在无法解释的心动过速而进行了 Swan-Ganz 导管插入术。尽管术前没有心律失常，但在拔除导管时出现了室性心动过速。需要进行直流电复律。该患者在住院早期没有室性早搏，却在拔除 Swan-Ganz 导管时出现需要复律的室性心动过速，这表明拔除 Swan-Ganz 导管可能引发潜在的严重心律失常。从插入 Swan-Ganz 导管到拔除导管的整个过程中持续保持警惕至关重要。因此，我们建议由经验丰富的人员在心电图监测下拔除导管，并准备好利多卡因和除颤器。
