Transcranial doppler testing

The transcranial doppler test is the most sensitive way to detect holes in the heart, which are commonly missed with echocardiograms and even angiogram.

Holes in the heart allow the potential for deoxygenated unfiltered blood to pass into arterial circulation. Approximately 20% of the population has the potential for this hole to create active symptoms, resulting in fatigue, migraines, strokes and chronic ill health.


The test takes between 15 to 30 minutes to perform.

Salt water is agitated and injected into a vein while monitoring the brain blood flow with an ultrasound doppler.

Results are available immediately for discussion with Dr Hayter
