    this paper we describe the magnetocardiographic response to several autonomic function tests in healthy young male subjects. Changes found during the handgrip test and cold pressure test were minor. The effect of mental stress was also small, but in two healthy subjects significant T-wave alterations were described. Thus, non-specific T-wave changes may occur in subjects without known heart disease during sympathetic stimulation induced in this manne
