Key result
In patients hospitalized with COVID-19 pneumonia, electrocardiographic abnormalities including new-onset atrial fibrillation, right and left bundle branch blocks, and sinus tachycardia were significantly associated with increased in-hospital mortality.
Why the study?
Cardiovascular involvement is a significant cause of death in COVID pneumonia, and early electrocardiographic changes may predict cardiovascular involvement and mortality.
Population
250 consecutive patients with COVID-19 pneumonia admitted to the emergency
Comparison
Electrocardiographic abnormalities and their relation to mortality

Kaeley et al. (2022) conducted an observational in COVID-19 pneumonia (n=250). Electrocardiographic abnormalities (e.g., sinus tachycardia, atrial fibrillation, RBBB, LBBB) vs. Absence of specific electrocardiographic abnormalities was evaluated on In-hospital mortality (p=<0.00001). In patients hospitalized with COVID-19 pneumonia, electrocardiographic abnormalities including new-onset atrial fibrillation, right and left bundle branch blocks, and sinus tachycardia were significantly associated with increased in-hospital mortality.
