During haemorrhage, why does activation of the arterial chemoreceptor reflex, and the resultant tachypnoea, "mask" the bradycardia induced by the cardiac vagal C-fibre reflex?
Struggling to understand why the increase in ventilation causes a tachycardia that "masks" the bradycardia of the vagal C-fibre reflex in the heart, which as I understand it is activated earlier on during haemorrhage.
