Relationship between the ECG parameters and carboxyhemoglobin. Top left. Relationship between the maximum QT interval and the carboxyhemoglobin level. Top right. Relationship between the maximum corrected QT interval and the carboxyhemoglobin level. Bottom left. Relationship between QT dispersion and the carboxyhemoglobin level. Bottom right. Relationship between corrected QT dispersion and the carboxyhemoglobin level. The relationships between the maximum QT interval and carboxyhemoglobin are not significant, whereas the other relationships are all significant
