Effect of vagotomy and blockade of cardiac sympathetic nerve activity (CSNA) on the increased HR response by microinjection of CRF into the PH.
(A) Changes in HR, evoked by microinjection of CRF into the PH, before and after intravenous administration of vagotomy and propranolol (blockade of CSNA). (B) Group data showing the CRF-induced changes in average peak HR in rats before and after vagotomy and blockade of CSNA. Statistical significance was determined using Student’s t test. n.s. no significance, **P < 0.01.
