The incidence of significant arrhythmias and ST segment changes during barium enema examination (BE) was evaluated by Holter monitoring of 58 unselected patients over the age of 60 years. Forty percent of the group developed new significant arrhythmias of which the most common were frequent and/or multifocal premature ventricular contractions. Seven percent demonstrated ST segment depression. Administration of glucagon did not diminish the incidence of arrhythmias. Predictive factors for ECG abnormalities were advancing age, abnormal pre-BE-ECG, and pre-BE orthostatic hypotension. Analysis of arhythmias and response to phywiologic tension. Analysis of arrhythmias and response to physiologic manoeuvres suggested that the abnormalities were related to increased sympathetic tone which may be intensified by hypovolaemia resulting from routine bowel preparation.
通过对58名60岁以上未经过挑选的患者进行动态心电图监测，评估了钡剂灌肠检查（BE）期间严重心律失常和ST段改变的发生率。该组中有40%出现了新的严重心律失常，其中最常见的是频发和/或多灶性室性早搏。7%表现出ST段压低。给予胰高血糖素并未降低心律失常的发生率。心电图异常的预测因素是年龄增长、钡剂灌肠前心电图异常和钡剂灌肠前体位性低血压。心律失常分析及对生理应激的反应。心律失常分析及对生理操作的反应表明，这些异常与交感神经张力增加有关，而常规肠道准备导致的血容量不足可能会加剧这种情况。
