A companion report documents the clinical course of 20 patients with Stokes-Adams seizures who have been treated with various types of electronic cardiac pacemakers (1). This group includes 13 patients in whom internal implantable mercury battery powered pacemakers with a fixed ventricular rate were employed.1 Six patients in this group volunteered to return for physiological studies by cardiac catheterization technique. Other reports have dealt with the hemodynamic consequences of variable rate pacemakers at rest and during exercise in what might be termed acute observations in that the studies were performed at different cardiac rates over a short period of time—usually
