The study aimed at assessing the diagnostic ability of advanced electrocardiogram (ECG) analysis to predict the levels of NT-proBNP and Troponin I. ECG and the blood NT-proBNP and Troponin I were taken from 50 acutely carbon monoxide poisoned patients and 21 control subjects matched with age and sex. The severity of the studied cases was classified into mild, moderate, and severe using clinical classification. ECG parameters (RR interval, corrected QT (QTc) interval, P wave dispersion (Pwd)), and cardiac biomarkers (NT-proBNP and Troponin I) were significantly higher in cases than in control (p= 0.015, 0.008, 0.002, <0.001, and <0.001 respectively). Cut-off values resulted from combined ROC curves analysis can predict blood Troponin I more than 0.05 ng/ml and NT-proBNP more than 125 pg/ ml (with 88% and 84% accuracy respectively). In addition, two regression equations were developed using all studied ECG parameters to predict Troponin I and NT-proBNP (with 68% and 43% accuracy respectively). RR average, PR average, QRS average, QTd, QTc, and Pwd could be used to predict Troponin I and NT-proBNP levels with good accuracy in carbon monoxide poisoning patients.
