Traumatic Brain Injury (TBI)

QTVariability Index utilized in TBI

QTVariability Index has been utilized in cardiovascular medical research for more than 25 years. Many medical and technical journals have described the medical benefit of measuring the QTVariability Index in thousands of patients worldwide. Cardiac Markers has designed a much improved automated VS 3.0 software of the QTVariability Index algorithm.  Recently, an increasing body of research has indicated that QTVariability Index is a relevant measurement of the autonomic nervous system changes in cardiac activity following the occurrence of a TBI event.

Tools required to measure TBI

• Cardiac Markers VS 3.0 QTVariability Index software

And one of the following

• Single Lead ECG
• Three lead Holter ECG
• Certain smartwatches with ECG capabilities

Expected Results

It is expected the physician will be able to measure trends of the autonomic nervous system.  The patient will be monitored for an extended time.  The physician will be alerted to the autonomic nervous system changes within the patient before they become an observable medical issue. The testing time is brief (3 minutes or less) and is non-invasive.

Statistics for TBI in the USA

• 5 million individuals have TBI annually that results in 50,000 deaths.
• 80,000 TBI patients suffer permanent disability.
• Annual overall cost of TBI is estimated at $48.3 billion. $31.7 billion for hospitalization and $16.6 billion goes toward cost associated with fatalities.
• The cause of TBI is falls, vehicle-related collisions, violence, sports injuries, explosive blasts, and other combat injuries.
• 13%-15% of TBI result in Cardiac Vascular Disease.
