Cardioinhibitory and vasodepressor forms of sick sinus syndrome may be revealed by tilt table testing.
2.
Vasodepressor syncope or vasovagal syncope ( VVS ) originates with activation of specific areas in the cerebral cortex.
3.
The abnormality is known variously as neurally mediated hypotension, vasovagal syncope ( fainting ), vasodepressor syncope and neurocardiogeneic syncope.
4.
The abnormality is known variously as neurally mediated hypotension, vasovagal syncope ( fainting ), vasodepressor syncope and neurocardiogenic syncope.
5.
A second theory as to why syncope may occur in AS is that during exercise, the high pressures generated in the hypertrophied left ventricle cause a vasodepressor response, which causes a secondary peripheral vasodilation that, in turn, causes decreased blood flow to the brain resulting in loss of consciousness.
