I don't think the nursing will interfere very much with the overall test,
unless mom's symptoms are occuring while breastfeeding.  The Holter comes
with a diary in which the person should record symptoms and activity.
Simply noting "breastfeeding" in the diary for the appropriate times will
allow the test to be interpreted accurately if there is any interference.
