20 days before admission	Symptom onset (cough and dizziness).
6 days before admission	Persistent fever unresponsive to antipyretic drugs and gradually worsening shortness of breath.
Admission	Diagnosis of pneumonia, suspected for coronavirus disease (COVID-19), with two real-time reverse transcription–polymerase chain reaction (RT–PCR) assays on nasopharyngeal swabs negative for SARS-CoV-2 infection.
Day 1–7	Non-invasive ventilation and antibiotic therapy.
Day 8	Electrical storm due to sustained episodes of ventricular tachycardia (VT) in absence of acute cardiac precipitating factors. Device detection of sustained and non-sustained VT episodes, started from the onset of COVID-19-related symptoms.
Day 9	Substrate-based VT catheter ablation targeting local abnormal ventricular activity (LAVA) with a remote magnetic navigation system.
Days 10–14	Absence of VT recurrence. Third nasopharyngeal swab positive for SARS-CoV-2 infection. Resolution of COVID-19 pneumonia.
Day 15	Discharge in home isolation.
Two months after discharge	Absence of ICD shocks.
