Changes in Heart Rate During Levarterenol Infusion

Abstract
Studies in this laboratory have demonstrated varying responses in heart rate during levarterenol-induced hypertension. A decreased bradycrotic response did not seem to depend on the age of the patient, the control level of arterial pressure or the percentage increase in mean arterial pressure. The present study was designed to evaluate the factors which govern the changes in heart rate during levarterenol infusion.
