This is the same patient from case 1. An 81-year-old male patient with a history of ischemic heart disease (severe stenosis of the proximal LAD coronary artery, RCA, and CX artery), with mild-to-moderate LV systolic dysfunction (LVEF of 45%), ischemic stroke, COPD, diabetes mellitus, and chronic lower limb ischemia is admitted to the Cardiology Department due to an episode of sustained monomorphic ventricular tachycardia in the context of an NSTEMI. Coronary angiography demonstrated severe triple vessel disease, and the patient underwent triple CABG. Four days after the surgical intervention, the patient presented a new episode of palpitations. This is presented in Fig. 1.
