“To provide accurate, affordable screening tools for the early detection of heart disease through continuous development of innovative electrocardiography.”

The Problem

Heart Disease Is The Leading Cause Of Death Worldwide


US Healthcare Costs in Billions                                                       


Cardiac Testing Today


Asymptomatic Patient Screening

  • Not done on a routine basis because effective low cost tools are not readily available

Symptomatic Patient

  • ECG Test – Lack of sensitivity as a screening test but used regularly to determine if a heart attack has taken place $50-$200
  • ECG based stress test – Improved sensitivity over standard ECG $250+
  • CT Scan – Used for obtaining a calcium score $200+
  • CT based Angiogram – An alternative to nuclear stress test $600+
  • Nuclear Stress Test – Test showing blood flow to the heart tissue $600+
  • Echocardiogram – Used for detecting structural abnormalities $500+
  • Invasive Angiogram – Gold standard for detecting CAD $5,000+

Lack of Innovation

  • ECG invented before electronics, computers, and software (Circa 1903)
  • Medical community has many established practices and procedures using traditional ECG technology
  • Technology until recently was not available to properly analyze additional signal data that has been present
  • Skills necesary to innovate in this area require multiple disciplines that include mathematics, programming, and a deep knowledge of cardiac function
  • Significant research required to assess the value of using other waveforms and metrics to provide valuable clinical information
