• Potassium chloride in a dose of 3 to 5Gm. was administered orally in 11 normal subjects and 49 patients with ventricular hypertrophy, bundle branch block or myocardial infarction. The resulting electrocardiographic changes were examined with the mean QRS, T and the ventricular gradient (G) vec-tors. Frank's lead system was used for analysis.After potassium administration, the QRS vector was decreased in mag-nitude in one third of the cases, but the grade of this change was not marked in most of them. The G vector increased its magnitude with relatively small change in its direction in most of the cases. Changes in the T vector occurred according to the relative orientation of the original QRS and T vectors. In some cases, however, the G vector changed its direction slightly anteriorly.Discussions were made on the practical value of the procedure and on the mechanisms of the observed changes.
