title: [Auricular adynamia due to hyperkalemia].
abstract: Auricular asystoly (A.A.) was the electrocardiographic pattern of 6 patients admitted for electrolytic disorders secondary to either renal failure or inadequate treatment. A rapid increase of blood potassium was the unique commun abnormality found to explain the dysrhytmia. Bradycardia (between 25 and 55 beats/mn) was present in each case with or without clinical symptoms. Temporary prophylactic pace maker insertion was performed in 4/7 patients. Recovery appeared after dialysis treatment in 6 cases, medical treatment in one, sinus rhythm being present in 6 and chronic atrial fibrillation in one. Prognosis of A.A. due to hyperkaliemia is good when hydroelectrolytic disorders are rapidly corrected. Follow up of blood electrolytes and electrocardiogram must be regular to prevent reccurencies.
