AI-guided Detection of Heart Disease in Routine Practice by Colleen Fleiss on May 9, 2021 at 11:41 AM Artificial intelligence (AI) screening helps detect low ejection fraction using data from an EKG could improve the diagnosis of this condition in routine practice. Study findings are published in Nature Medicine. Systolic low ejection fraction is defined as the heart's inability to contract strongly enough with each beat to pump at least 50% of the blood from its chamber. An echocardiogram can readily diagnose low ejection fraction, but this time-consuming imaging test requires more resources than a 12-lead EKG, which is fast, inexpensive and readily available. The AI-enabled EKG algorithm was tested and developed through a convolutional neural network and validated in subsequent studies.
