COVID-19 carries an elevated risk of heart-related complications, especially in individuals with prior health conditions linked to pre-existing inflammation. Complete heart block has typically been documented as a temporary condition in such patients, rarely requiring long-term intervention. However, an account of a previously healthy woman diagnosed with SARS-CoV-2 infection shows she developed complete heart block that did not resolve alongside the virus. Following effective treatment and a confirmed negative test for the infection, she required the implantation of a permanent dual-chamber pacemaker before being discharged safely. The ongoing electrical dysfunction of the heart after the viral clearance suggests a possible direct link between SARS-CoV-2 and persistent conduction abnormalities. Electrographic assessments could therefore be vital during early clinical evaluations of suspected cases, even when individuals have no previous cardiac issues.
While complete heart block during viral illnesses is often temporary, this evidence shows it can cause lasting damage requiring permanent medical hardware. Understanding that serious cardiac conduction issues can occur in previously healthy patients helps clinicians detect silent, life-threatening complications earlier and adapt monitoring protocols for individuals recovering from viral infections.
The abstract does not indicate an application pathway, as it represents a clinical case report highlighting the need for early electrocardiographic screening and further medical research rather than a proprietary product or technology.

There is an increased risk of cardiac complications in COVID-19 among patients with pre-existing comorbidities due to their existing pro-inflammatory status. The manifestation of complete heart block has been evidenced as transient and in no need of intervention. This case presents a previously healthy woman who was diagnosed with SARS-CoV-2 infection and complete heart block; she underwent permanent dual-chamber pacemaker implantation after successful treatment and a negative COVID-19 test. She was then discharged from the hospital with an uneventful follow-up. Persistence of complete heart block symptoms post-COVID-19 resolution and the need for permanent pacing indicate a potential association between COVID-19 and complete heart block. Healthcare workers should consider electrographic examination in the initial assessment of suspected COVID-19 cases, even among those with no pre-existing conditions. This report highlights the need for further research to explore the relationship between COVID-19 and complete heart block.
