Arrhythmia With Lithium Toxicity Requiring Urgent Dialysis: A Case Report.

Lithium has been widely used as a mood stabilizer. With its narrow therapeutic index, systemic side effects, primarily neurological are a concern. Cardiotoxic effects of lithium are rare, reported as non-specific T-wave flattening, prolonged QT interval, sinus node dysfunction, ventricular tachycardia, cardiomyopathy, and myocardial infarction. We report an interesting case of a young female patient with schizoaffective disorder on lithium who developed life-threatening cardiotoxicity secondary to lithium requiring urgent dialysis.
