Arrhythmias During Upper Gastrointesintal Endoscopy

Abstract

Electrocardiographic monitoring of 52 consecutive patients undergoing upper gastrointestinal endoscopy revealed that arrhythmias during the procedures were common (38.5%) and tended to occur more frequently in the elderly (75%), in persons with heart disease (54.5%), and in persons with chronic lung disease (89%). The incidence of ventricular premature contractions in patient with no evidence of heart or lung disease was 19%. In one patient with advanced chronic lung disease, the procedure had to be terminated because of development of high-degree atrioventricular block. A high incidence of arrhythmias during endoscopy has not been previously reported in patients with chronic lung disease.
