Key result
Electrocardiogram interpretation in poisoned patients provides a structured approach to identify classic ECG changes indicating ion channel blockade, altered adrenergic tone, or metabolic dysfunction.
The ECG provides a rapid, structured approach to identifying ion channel blockade, adrenergic tone alterations, and metabolic dysfunction in poisoned patients to guide initial management.
The ECG is a rapidly available clinical tool that can help clinicians manage poisoned patients. Specific myocardial effects of cardiotoxic drugs have well-described electrocardiographic manifestations. In the practice of clinical toxicology, classic ECG changes may hint at blockade of ion channels, alterations of adrenergic tone, or dysfunctional metabolic activity of the myocardium. This review will offer a structured approach to ECG interpretation in poisoned patients with a focus on clinical implications and ECG-based management recommendations in the initial evaluation of patients with acute cardiotoxicity.

Yates et al. (2012) conducted a review in Drug overdose and poisoning. Electrocardiogram (ECG) was evaluated. Electrocardiogram interpretation in poisoned patients provides a structured approach to identify classic ECG changes indicating ion channel blockade, altered adrenergic tone, or metabolic dysfunction.
