Heart rate and arterial pressure variability and baroreflex sensitivity in ovariectomized spontaneously hypertensive rats.

Aims: The present study evaluated the effects of ovariectomy on heart rate and arterial pressure variability and cardiac baroreflex sensitivity (BRS) in female spontaneously hypertensive (SHR) and Wistar-Kyoto rats (WKY).

Main Methods: Sham-surgery animals were used as control. Sixteen weeks after ovariectomy or sham-surgery, animals were recorded.
