Atrial fibrillation (a disturbance in the rhythm of the heartbeat) may go unnoticed on the ECG. Especially when the rhythm of the heartbeat returns to normal for a while. Artificial intelligence created by the Mayo Clinic will help to avoid a fatal diagnostic error, reports BBC. Scientists have revealed signs of arrhythmia hidden from the doctor’s eye.
The computer is looking for seemingly insignificant traces that speak of past episodes of heart rhythm failures. Such traces include the formation of scar tissue on the heart. The system analyzed studies of the heart rate of almost 181,000 people from 1993-2017. All people initially had normal tests. But artificial intelligence revealed arrhythmia in 83% of studies labeled as “normal.”
There is no doubt in the power of artificial intelligence. For example, a computer recently developed a high-performance flu vaccine. The vaccine was created by a program known as the Ligand Search Algorithm. Ligands are compounds (sometimes a small molecule) that form complexes with a biological molecule (with DNA, protein, cell receptor) and, as a result, produce certain effects.
