Central venous catheters extending into intracardiac chambers can provoke premature atrial and ventricular complexes, which have been reported to initiate supraventricular tachyarrhythmias. These catheters are traditionally placed via the femoral, subclavian, or internal jugular veins. A new alternative to the conventional central catheter for patients requiring access to large veins is the peripherally inserted central (PIC) catheter. Since its proximal end is of small caliber, a PIC catheter can be mistaken for a peripheral intravenous catheter. The distal end, however, usually extends into the superior vena cava and may be erroneously advanced into intracardiac chambers. The authors report a case of a PIC catheter precipitating supraventricular reentrant tachycardia in a previously asymptomatic patient.
延伸至心腔内的中心静脉导管可诱发房性和室性早搏复合波,据报道这些复合波可引发室上性快速性心律失常。传统上,这些导管是通过股静脉、锁骨下静脉或颈内静脉放置的。对于需要接入大静脉的患者,一种替代传统中心静脉导管的新方法是经外周静脉穿刺中心静脉置管(PIC)。由于其近端管径较小,PIC导管可能会被误认为是外周静脉导管。然而,其远端通常会延伸至上腔静脉,并且可能会错误地推进到心腔内。作者报告了一例PIC导管在一名先前无症状的患者中诱发室上性折返性心动过速的病例。
