Hyperbaric oxygen therapy decreases QTc dispersion that increased in CO poisoning

摘要

Myocardial injury is a frequent consequence of moderate to severe CO (carbon monoxide) poisoning and a significant predictor of mortality in CO injury. Electrocardiography (ECG) is an easily accessible diagnostic tool for evaluating myocardial damage. Increased QT interval and QT dispersion are related to heterogeneity of regional ventricular repolarization and can develop into arrhythmias. It has been reported that QT interval and QT dispersion increase in patients with CO poisoning.
