SYNOPSIS The cardiovascular reflex responses of 10 migraine patients were recorded during both migraine attacks andheadache‐free intervals. Ten healthy subjects of similar age and sex served as a control group.When the results of the measurements for migraine patients performing an isometric work test duringmigraine attacks and during headache‐free intervals were compared, during migraine attacks a statisticallysignificant smaller increase in diastolic B.P. was encountered than interictally (p<0.05).When the results for migraine patients during migraine attack, and controls, were compared, statisticallysignificant differences were encountered in the pulse rate variation in Valsalva manoeuvre, in an orthostatictest, and in the systolic and diastolic blood pressure reactions in an isometric work test. The mean Valsalvaratio and R‐R‐interval ratio during the orthostatic test were lower in migraine patients during migraine attackthan in controls, and the mean blood pressure rise in the isometric work test was also lower in the migrainepatients group during attacks.There were no statistically significant differences between the results of the migraine patients duringheadache‐free intervals and those of the control subjects.
