1. A system for ambulatory monitoring of vasoactivity in a patient, comprising:
a sensor circuit configured to generate a heart sound (HS) metric using a HS signal sensed from the patient; and
a control circuit, including: a vasoactivity monitor configured to monitor vasoactivity and determine a degree of vasodilation using the generated HS metric; and a vasovagal surge detector configured to detect a vasovagal surge using the determined degree of vasodilation.
