title: Serious sinus node dysfunction caused by therapeutic doses of lithium.
abstract: We studied an exceptional case of a patient showing serious sinus node dysfunction during lithium treatment with levels constantly within the therapeutic range. After two endocardial explorations we found that the sinus node dysfunction was due to lithium and reversible after its withdrawal.
