The electrocardiograms before the procedure showed no cardiac rhythm disturbances in 20 (67%) patients. However, two (7%) patients had pre-existing atrial fibrillation, five (16 %) patients had premature atrial complexes and three (10%) patients had premature ventricular complexes. During the procedure, premature atrial complexes appeared in 19 (63%) patients, premature ventricular complexes appeared in nine (30%) patients, a burst of supraventricular tachycardia developed in one (3%) patient, a short run of ventricular tachycardia appeared in one (3%) patient and transient left bundle branch block (LBBB) in one (3%) patient. The patient with the LBBB was hypertensive, had cardiomegaly in the chest radiograph and developed premature complexes. Significant differences were found upon comparing the absolute number of atrial and ventricular premature complexes during ERCP and the baseline period (Table 3). In comparing the arrhythmias appearing in the control group during chest, bone, abdomen and upper gastrointestinal small bowel follow-through with the baseline period, significant differences were not found.
The number of patients in whom premature atrial complexes, sinus tachycardia and premature ventricular complexes developed during ERCP was significantly larger than the control group.
