Abstract
A pressure cuff on the patient is inflated to a predetermined pressure above systolic, and then is deflated incrementally. At each decrement, oscillatory complexes are detected, and respective peaks are compared and evaluated as "true" complexes if they are within certain size matching criteria. After such "true" complexes are identified at a predetermined number of levels (e.g. 2 or 3), only a single complex is investigated at subsequent levels, provided specified size and timing criteria are met.
