The present study shows that arrhythmias of all kinds, conduction disturbances, electrocardiographic changes compatible with myocardial ischemia and oxygen desaturation are encountered in elderly patients undergoing ERCP. There are previous studies using hemodynamic monitoring (heart rate, blood pressure, rate pressure product), pulse oxymetry and electrocardiographic monitoring during gastrointestinal endoscopic procedures which associate cardiac risk with changes observed in heart rate, asymptomatic arrhythmias, ST segment changes, oxygen desaturation and changes in blood pressure. Some studies have suggested that patients with heart disease were at an increased risk during the above procedures.
In one study including 52 consecutive patients undergoing upper gastrointestinal endoscopy, arrhythmias during the procedure were common and tended to occur more frequently in the elderly and in persons with heart disease and chronic lung disease. In another study patients with cardiac history, before esophageal dilation, were particularly prone to cardiorespiratory events. It was found that 90% of patients with pre-existing cardiac disease developed an event during the procedure.
Other studies have shown that patients with increased age are particularly prone to low oxygen saturation, pain during the procedure and increased duration of the procedure.

The current study suggests also that electrocardiographic and laboratory changes during ERCP are frequent, especially in elderly patients with coexisting cardiac disease. These changes, however, seem to be asymptomatic. The abnormalities observed ranged from sinus tachycardia to innocent and transient atrial and ventricular premature beats as well as ST segment changes and oxygen desaturation.
