A 70-year-old male patient with liver steatosis and prostatic carcinoma presented to the emergency department with pre-syncope and symptoms of congestive heart failure.
Initial evaluation revealed tachycardia, normal blood pressure, and signs of pulmonary congestion. Blood analyses showed elevated natriuretic peptides, with no other significant alterations.
A 12-lead ECG was performed (Fig. 1). What is the diagnosis, and should we shock it or not?
