lithium toxicity, asystolic arrest, mood stabilization in bipolar disorder,


Lithium is commonly prescribed for mood stabilization in bipolar disorder. Lithium has a narrow therapeutic range (0.8−1.2 mmol/L), and even chronic users may unexpectedly develop toxic levels. Toxicities manifest in various ways. The authors report the case of a patient who developed sinus bradycardia and asystolic arrest with an elevated serum lithium level.
