Conclusion
This study indicate that SARS-CoV-2 infection can cause malignant arrhythmia episodes through various mechanisms, including myocardial damage, electrolyte disturbances, QT interval prolongation, HF aggravation, and AF induction, resulting in a significant increase in the number of ICD treatments administered. Patients with ICDs should be treated cautiously following SARS-CoV-2 infection. Early intervention and more active follow-up should be provided to minimize the likelihood of ICD shock and improve patients’ prognosis. Ultimately, this study provides a basis for the future diagnosis and treatment of patients with such devices following similar infectious disease outbreaks.
