The authors studied the monthly electrocardiographic tracings of 27 children with normal cardiovascular function receiving imipramine therapy for enuresis. They found no substantial EKG changes in any of these children, who were receiving doses of 25 to 75 mg of the drug. They conclude that electrocardiographic monitoring may be essential only when more than 25 to 75 mg of imipramine is given and that it should be established that the patient's cardiovascular function is normal before the drug is administered.
