Discussion on the value of bradycardia patients with Atropine test in preoperative

Objective To monitor Atropine test to patients with sinus bradycardia, and provide a reference for the clinical safety of operation. Methods Four hundred and fifteen patients with sinus bradycardia were given Atropine test before surgery in our hospital from March 2006 to August 2011, intravenous injection of Atropine 2.0 mg was completed within 1 minute, ECG changes was observed for 15-20 min.
