Of 18,365 patients who underwent coronary angiography with a 4F or 5F universal catheter between April 2004 and May 2007, 24 (0.131%) experienced sustained ventricular tachycardia or ventricular fibrillation during the procedure. There was no significant difference in any clinical or angiographic characteristic between patients who had a ventricular arrhythmia and those who did not. Of the 24 episodes of ventricular arrhythmia, 14 were related to catheter manipulation, 8 to ischemia, and 2 to the contrast medium, while the cause could not be clearly established in 4. The incidence of ventricular arrhythmia with a universal catheter was 0.131%, and with a preformed catheter, 0.054% (P=.72). The study shows that serious ventricular arrhythmia occurs only rarely as a complication when coronary angiography is carried out using modern techniques and that imperfect manipulation of the catheter explains most episodes.
在2004年4月至2007年5月期间，18365例使用4F或5F通用导管进行冠状动脉造影的患者中，有24例（0.131%）在手术过程中出现持续性室性心动过速或室颤。发生室性心律失常的患者与未发生室性心律失常的患者在任何临床或血管造影特征上均无显著差异。在这24次室性心律失常发作中，14次与导管操作有关，8次与缺血有关，2次与造影剂有关，4次病因无法明确。使用通用导管时室性心律失常的发生率为0.131%，使用预制导管时为0.054%（P = 0.72）。该研究表明，在使用现代技术进行冠状动脉造影时，严重室性心律失常作为并发症很少发生，且大多数发作是由导管操作不当引起的。
