Heart Failure is one of the most serious cardiovascular diseases across the world with a prevalence of close to 64 million patients across the globe. While diagnosis and prognosis of Heart Failure predominantly depends on LVEF, it has quite a few backdrops. A novel technology has emerged (patented by USPTO) wherein LVEF can be calculated from ECG graphs. This is sure to have a huge impact on healthcare at a global scale once the technology will be adapted into the modern-day ECG, Holter and Cardiac Monitoring machines.
