A 72-year-old male patient with a history of aborted sudden cardiac death (2018), implanted with a Boston Scientific single-chamber ICD for the secondary prevention of SCD, MINOCA (presence of a reduced area of necrosis of the LV anterior wall on cardiac MRI), and LVEF of 50%, is admitted to the Cardiology Department for an episode of palpitations accompanied by anxiety and lightheadedness that had occurred 30 min prior to his presentation to the hospital. The VT detection window of his ICD was programmed between 170 and 230 bpm. His ECG recorded at admittance to the Cardiology Department is presented in Fig. 1.
