Electrocardiogram (ECG) abnormalities are frequently observed in hospitalized COVID\u201019 patients, some of which are associated with increased mortality. It is unclear whether ECG abnormalities occurring before hospitalization are associated with increased mortality. This quantitative systematic literature review aims to determine which ECG changes occurring before hospitalization are associated with mortality and discuss whether these findings can aid the assessment of patients and decision\u2010making in the pre\u2010hospital environment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A systematic search of the following digital databases was conducted: CINAL, PUBMED, MEDLINE, and Coronavirus Research Database. Eight cohort studies (primary papers) including COVID\u201019 patients with ECGs taken in the Emergency Department before hospitalization were selected for quantitative synthesis and results were obtained for the prevalence of ECG changes among survivors compared with non\u2010survivors.
