ecg prediction of mortality in covid-19 patients by sokolow-lyon voltage

Background: different electrocardiographic (ecg) results, seen in coronavirus disease 2019 (covid-19) patients are most likely due to the combined impact of acute covid-19 and chronic heart disease. few studies have addressed the effects of hypoxemia, the hallmark of the pandemic disease, on ecg. objectives: the present study discusses the prevalence of arrhythmias and disorders of conduction system in demised and survived covid-19 patients, using ecg and sokolow-lyon voltage as a sign of hypoxemia to predict mortality in the admitted patients and after discharge. methods: we investigated the ecg, and other medical data of 960 covid-19 patients admitted to faghihi hospital in shiraz, iran, from august 2021 to december 2021. results: most of the patients were male (541 or 56.4%) and older than 65 years old (462 or 48.1%). a total of 475 (49.5%) patients died. multiple logistic regression revealed an independent association between the covid-19 death rate and cardiovascular disease (or = 3.05; 95% ci: 1.96 - 4.74), qt dispersion more than 40 (or = 5.08; 95% ci: 3.61 - 7.15), heart rate (more than 100 versus less than 60 or = 2.86; 95% ci: 1.03 - 7.9), st segment elevation myocardial infarction (or = 3.93; 95% ci: 2.63 - 5.86), poor progression (or = 2.33; 95% ci: 1.56 - 3.49), hypertrophy (or = 1.97; 95% ci: 1.02 - 3.81), and sokolow-lyon (or = 2.91; 95% ci: 1.64 - 5.16). conclusions: electrocardiographic examination of covid-19 patients is important during admission and after discharge. sokolow-lyon voltage less than 10 can be regarded as an independent predictor of mortality in covid-19 patients discharged from hospital.
