Key result
Asymptomatic SARS-CoV-2 infection is linked to extreme QTc prolongation peaking at ~720 ms.
Why the study?
Does asymptomatic SARS-CoV-2 infection cause significant QTc prolongation and T-wave inversions in patients with cardiac comorbidities?
Case Report (n=1)
Does asymptomatic SARS-CoV-2 infection cause significant QTc prolongation and T-wave inversions in patients with cardiac comorbidities?
This case highlights that SARS-CoV-2 infection may have intrinsic effects on cardiac repolarization, causing severe QTc prolongation even in asymptomatic patients.
Asymptomatic SARS-CoV-2 may cause torsades-risk QTc prolongation in patients with cardiac comorbidities; single case leaves open prevalence and reversibility.

Anand et al. (2021) conducted a case report in Asymptomatic COVID-19 infection (n=1). SARS-CoV-2 infection was evaluated on QTc prolongation. Asymptomatic SARS-CoV-2 infection was associated with extreme QTc prolongation, peaking at 720 ms, and deep T-wave inversions without evidence of overt myocardial injury.
