Pyrogen reaction and conversion of sustained ventricular tachycardia to sinus rhythm: two case reports

摘要

Introduction Pyrogen reaction is a side effect of intravenous infusion of solution on body; sustained ventricular tachycardia is a serious arrhythmia, no relationship between them has been reported before. Case presentation Two patients with sustained ventricular tachycardia refractory to lidocaine happened to have pyrogen reaction. The sustained ventricular tachycardia was converted to sinus rhythm after the pyrogen reaction. Conclusion The conversion of sustained ventricular tachycardia might be related to pyrogen reaction. The effects of pyrogen reaction on sustained ventricular tachycardia need further research.
