Key result
Lithium toxicity manifests as reversible CHB, AF, and sinus bradycardia in a single patient.
Why the study?
Lithium toxicity has a narrow therapeutic index with cardiovascular effects ranging from benign ST-T changes to fatal arrhythmias, requiring detailed characterization of ECG manifestations.

Recognizing reversible bradyarrhythmias may aid lithium toxicity management; one case leaves open systematic study of incidence.
Case Report (n=1)
Lithium toxicity can present with a wide variety of reversible electrocardiographic manifestations including junctional rhythm, complete heart block, and atrial fibrillation.
A 2017 study conducted a case report in Lithium toxicity (n=1). Lithium toxicity was evaluated on Electrocardiogram manifestations. Lithium toxicity in a single patient manifested as a junctional rhythm, complete heart block, atrial fibrillation, and sinus bradycardia, which reverted to sinus rhythm as serum levels normalized.
