The effect of propofol on frontal QRS‐T angle in patients undergoing elective colonoscopy procedure

Abstract

In this study, we found that propofol administration increased the frontal QRS-T angle in patients undergoing colonoscopy procedure. Given that a prolonged frontal QRS-T angle is associated with ventricular arrhythmias, it may be safer to monitor those patients receiving propofol during colonoscopy procedures.
