Summary A spatial vectorcardiogram (VCG), employing the Frank reference system, was recorded for 29 normal beagle dogs. The QRS loop was elliptical to ovoid and oriented to the left inferior quadrant in the frontal plane, to the left anterior quadran

Measurements with the Wells-Brookfield cone-plate microviscometer revealed no significant differences in blood viscosity between controls and female beagles exposed to laboratory produced air pollutants daily for 4 years, despite significant elevatio
