ABSTRACT:
An apparatus for non-invasive diagnosis of states of vasovagal syncope in a patient placed on a tilt table and subjected to a tilt-test, the apparatus comprising: circuits for sensing the patient's endocardiac acceleration; circuits for sensing the patient's heart rate; and analyzer circuits receiving as inputs said endocardiac acceleration and said heart rate, and outputting information about the sympthetico-vagal activity of the patient. The circuits for sensing endocardiac acceleration comprise an external accelerator sensor suitable for being held in contact with the patient's rib cage. The analyzer circuits comprise classifier circuits suitable, in the event of a syncope occurring, for determining one type of syncope amongst a plurality of syncope types as a function of the endocardiac acceleration and heart rate values sensed during a plurality of heart cycles preceding the occurrence of the syncope.
