- A coronary angiogram was performed with results showing “near normal coronary arteries” with no major disease identified.
- An echocardiogram was also conducted showing no major pathology.
- A CT brain scan was performed on Lindsey with the results stating “diffuse cerebral oedema”, and quoted by the medical team as a “catastrophic brain injury”, none like they have seen before in such a short time frame. This was 4-5 hours after the grand mal seizure.
