1. In renal hypertensive dogs, the slope of the relation between either stroke volume or cardiac output and end-diastolic pressure is shifted to the right of the normal curves. 2. The maximum to which stroke volume or cardiac output can be raised during loading is significantly less. These changes in cardiac performance appear to be unrelated to the severity of hypertension.
The difficulties involved in recording high-quality electroencephalograms chronically from conscious dogs have been resolved by devising an implantable pure silver electrode assembly that can be screwed permanently into the skull. The assembly eliminates electromyographic artifacts and provides high-fidelity tracings. Construction is simple and commercially available, inexpensive parts are used. Highly satisfactory records can be obtained over periods of months.
