In 8 guinea pigs under local or general anesthesia, systolic and diastolic end pressures in the carotid artery averaged 77 and 47 mm Hg respectively. The calculated mean pressure averaged 57 mm Hg. The portion of the cardiac cycle taken up by systole was greater than that described for other small mammals in about 40% of the measurements.
