Intracavitary electrocardiogram (IC-ECG) guidance is widely used for peripherally inserted central catheter (PICC) placement. The P wave variation has rarely been reported in persistent left superior vena cava (PLSVC). Here, we report a PLSVC case of P wave variation in PICC placement guided by IC-ECG. In this case, the P wave variation of the PLSVC was quite different from that of the right superior vena cava (RSVC). The tip of the catheter was located at the lower segment of the left superior vena cava according to postoperative radiography examination. PICC functioned normally, and no complications occurred.
腔内心电图（IC-ECG）引导广泛应用于经外周静脉穿刺中心静脉置管（PICC）。持续性左上腔静脉（PLSVC）患者中P波变化鲜有报道。在此，我们报告1例在IC-ECG引导下行PICC置管时出现P波变化的PLSVC病例。该病例中，PLSVC的P波变化与右上腔静脉（RSVC）的P波变化有很大不同。术后影像学检查显示导管尖端位于左上腔静脉下段。PICC功能正常，未发生并发症。
