Relationship between ECG Findings and Serum Biomarkers in COVID-19 Patients

Abstract Background and aim: The aim of this study was to evaluate the relationship between ECG findings blood parameters indicative inflammation myocardial injury in COVID-19 patients. Methods: included 159 females 194 males. Demographics, (axis, rhythm, branch block, ST- T-wave changes, premature ventricular contractions, early repolarization, S1Q3T3, fragmented QRS [fQRS], rate, PR, QRS, QT interval, QTc, P-wave dispersion) albumin, D-dimer, ferritin, pro-BNP, procalcitonin, protein, troponin T, neutrophil-to-lymphocyte ratio (NLR), C-reactive protein/albumin (CAR) were recorded. Results: In study, 45% cases female 55% male. mean age patients 45.7 ± 24.4 years. most frequent comorbidities chronic obstructive pulmonary disease (COPD) hypertension (HT) both groups. incidence fQRS on 1st day significantly higher with negative test (23% for positive RT-PCR versus 35.6% RT-PCR, p = 0.016). QTc values 3rd 5th (p 0.045 0.042, respectively). Albumin procalcitonin results 0.018 <0.001, Patients presented lower serum albumin (40.62 4.73 g/L vs. 42.92 3.72 g/L, 0.01), protein levels 0.02), as well lymphocyte count, (47.01 65.01 mg/L 24.55 44.17 mg/L, 0.001), D-dimer 0.009), neutrophil pro-BNP 0.004), T <0.001), NRL CAR (1.28 1.83 0.6 1.11, <0.001). Conclusion: infection neutrophil, NLR, CAR, proteins, indicating level its injury. Further follow-up studies are required, larger patient sets, development risk prediction tools
