Over an 11-month period (November 1992 to October 1993), 32 radiofrequency catheter ablations were performed for recurrent symptomatic supraventricular tachycardia in 17 patients with atrioventricular (AV) nodal reentry, 13 with AV reentry with an accessory pathway), and 2 with both AV and AV nodal reentry. Each patient underwent both diagnostic and therapeutic electrophysiologic study with radiofrequency catheter ablation in a single session. Twelve of the 32 patients had recurrent symptoms after catheter ablation. A repeat study was performed in 9 of the 12 patients. At 7.7 +/- 0.8 months (range 4 to 11) of follow-up only one patient had had a true symptomatic recurrence. Additional sessions of ablation cured this patient. We conclude that pseudorecurrence of paroxysmal supraventricular tachycardia is a common phenomenon in patients after radiofrequency catheter ablation. Follow-up electrophysiologic study demonstrates and helps differentiate pseudo from true paroxysmal supraventricular tachycardia recurrence.
在11个月期间（1992年11月至1993年10月），对17例房室结折返性心动过速、13例伴有附加旁路的房室折返性心动过速以及2例同时存在房室和房室结折返性心动过速的复发性症状性室上性心动过速患者进行了32次射频导管消融术。每位患者在单次手术中均接受了诊断性和治疗性电生理研究及射频导管消融术。32例患者中有12例在导管消融术后出现复发性症状。对这12例患者中的9例进行了重复研究。在7.7±0.8个月（范围4至11个月）的随访中，仅有1例患者出现了真正的症状复发。额外的消融治疗使该患者痊愈。我们得出结论，阵发性室上性心动过速的假性复发在射频导管消融术后患者中是一种常见现象。随访电生理研究可证实并有助于鉴别假性与真正的阵发性室上性心动过速复发。
