摘要: Aims Transient ST-T elevation (STE) is a rare complication that occurs during transseptal catheterization. This study aims to delineate the incidence and characteristics of transient STE catheterization for atrial fibrillation (AF) ablation. Methods results Consecutive patients who underwent fluoroscopy-guided circumferential pulmonary vein radiofrequency ablation in Beijing An Zhen Hospital from January 2006 2013 were enrolled this study. Out 2965 with total 3452 procedures, 13 (0.38%, mean age 57 ± 8, 6 female, 12 paroxysmal AF, left diameter 35.4 3.8 mm) had STE. occurred after puncture 10 venography three patients. Systolic blood pressure (129 vs. 104 20 mmHg, P < 0.001), diastolic (78 64 11 heart rate (83 19 bpm 23 b.p.m., = 0.022) significantly decreased when occurred. Eleven complained chest pain, one patient dizziness, no symptoms. Patients recovered about 4.6 min (2–10 min) dopamine or fast saline drip. Catheter AF was completed all without sequelae other complications. Four (30.8%) recurrence follow-up 21.7 months. Conclusion associated sequelae. could be safely these
