Electrical Effects of Stimulating the Endocardial Surface of the Right Ventricle of the Dog
The endocardial surface of the right ventricle in four dogs was stimulated by a unipolar electrode introduced into the cavity of the right ventricle by means of a catheter. Electrical changes at a suprajacent point on the right wall were recorded by the V lead method of Wilson. In every experiment the induced QRS complexes were initiated by a positive electrical change.
