1. A procedure is described by which means aberrant ventricular beats in the dog can be consistently obtained. 2. The results offer an explanation of the aberrant beats which have been occasionally recorded during vagal stimulation, both in the dog and in the human subject. 3. They indicate that the vagal stimulation in some way alters the impulse as it passes through the upper portions of the junctional tissues between auricle and ventricle, so that it is unable to pass a region of impaired conduction in a bundle branch, which the normal impulse can traverse without difficulty.
