Hyperaldosteronism presenting with repetitive Stokes-Adams attacks

Summary

AN unusual case of primary hyperaldosteronism, associated with longstanding and severe hypertension, which presented with repetitive Stokes-Adams attacks caused by ventricular dysrhythmias, is reported. It was found that when the Q-Tc interval of the electrocardiogram was prolonged by more than fifty per cent ventricular dysrhythmia almost invariably occurred. The close relationship of the onset of dysrhythmias to the increased Q-T interval rather than to the serum potassium levels is pointed out.
