On September 18th, 2023, the American Heart Association published clinical management guidelines for patients with poisoning-induced cardiac arrest and critical cardiovascular illness in Circulation. Considering the important role of the guidelines in clinical practice, our team has divided them into three sections for detailed interpretation based on the different toxic effects of the drugs. This article is the second part of the interpretation, which combines the literature to interpret the recommendations related to cardiotoxic substance poisoning in the guidelines, mainly involving the clinical management of beta blockers, calcium channel blockers, digoxin and other cardiac glycosides, as well as sodium channel blocker poisoning, aiming to assist colleagues in their clinical practice through a detailed explanation of the key recommendations in the guidelines.
