Machine Learning Control: Overview

Developed a smart bionic pacemaker controlled by a neural network

Scientists have created an intelligent bionic pacemaker that makes the heart beat at its natural rhythm, increasing the efficiency of pumping blood.

Currently used pacemakers cause contractions at a constant rate, but the functioning of a healthy organ depends on breathing. The rhythm accelerates with inhalation and slows down with exhalation. Although some devices can adjust the timing of contractions based on body temperature or average respiratory rate over a certain period, they remain monotonous..

A team of scientists from the Universities of Bristol and Bath has described a smarter pacemaker that helps the heart return to its natural rhythm.

The device uses a neural network-based analog chip that captures electrical signals that occur in the chest muscles with each breath. The system analyzes this information and corrects the work in real time, synchronizing the pacing of the left atrium with breath.

When tested on rats with heart failure, it increased the amount of pumped blood by 20% compared to monotonic pacemakers.

Many advanced technologies are used in medicine. We also previously reported on the development of artificial blood that is suitable for patients with any blood group and can be stored for more than a year..
