[Several cardiovascular manifestations induced by vibrational stimuli].
In normal man, tachycardia and digital vasoconstriction provoked by exposition to vibrations (50 Hz; 20 m.sec-2) are inhibited by adrenoceptor blockade, respectively metoprolol (100 mg per os) concerning tachycardia; prazosine (1 mg per os) concerning vasoconstriction.
