Cardioinhibitory Autonomic Mediated Syncope
These traces show the typical changes in systolic blood pressure and heart rate induced during a positive tilt table test.
Fifteen minutes into the test the BP (upper trace) fell precipitously from 140 mm Hg to 50 mm Hg and the heart rate (lower trace)
dropped from 65 beats per minute to 30 beats per minute. The patient developed typical symptoms.
Removing the tilt resulted in rapid recovery.
