Cadmium alters arterial baroreflex control of heart rate in the conscious rat.
In conscious rats, a single oral dose of cadmium (Cd) chloride (up to 150 mg/kg) does not alter mean arterial pressure, heart rate and pressor response to phenylephrine 3, 7, and 14 days after loading. However, 150 mg/kg of Cd reduce reflex bradycardia and increase centrally mediated vagal decrease in heart rate. Therefore, it is suggested that Cd could modify baroreflex control of heart rate through an impairment of the afferent component of the reflex.
