Cardiac arrhythmias have been observed in patients hospitalized with coronavirus disease (COVID-19). Most analyses of rhythm disturbances to date include cases of sinus tachycardia, which may not accurately reflect true cardiac dysfunction. Furthermore, limited data exist regarding the development of conduction disturbances in patients hospitalized with COVID-19. Hence, we performed a retrospective review and compared characteristics and outcomes for patients with versus without incident arrhythmia, excluding sinus tachycardia, as well as between those with versus without incident conduction disturbances. There were 27 of 173 patients (16%) hospitalized with COVID-19 who developed a new arrhythmia. Incident arrhythmias were associated with an increased risk of intensive care unit admission (59% vs 31%, p = 0.0045), intubation (56% vs 20%, p <0.0001), and inpatient death (41% vs 10%, p = 0.0002) without an associated increase in risk of decompensated heart failure or other cardiac issues. New conduction disturbances were found in 13 patients (8%). Incident arrhythmias in patients hospitalized with COVID-19 are associated with an increased risk of mortality, likely reflective of underlying COVID-19 disease severity more than intrinsic cardiac dysfunction. Conduction disturbances occurred less commonly and were not associated with adverse patient outcomes., Competing Interests: Disclosures The authors have no conflicts of interest to disclose., (Copyright © 2021.

Research on health security has focused on how many different political, economic, social, and health-related factors affect disease containment within states. However, largely missing from this scholarship is an examination of the role public health intelligence plays in limiting the spread of disease. Thus, this study focuses on the effect epidemiological intelligence fusion centers have on disease prevalence. We conduct a case study analysis of the Dominican Republic's use of epidemiological intelligence fusion centers during the COVID-19 pandemic and provide policy recommendations for other states to follow.
