Scientists have created an intelligent bionic pacemaker that makes the heart beat with a natural rhythm, increasing the efficiency of blood pumping.
Current pacemakerscause contractions with a constant frequency, but the work of a healthy organ depends on breathing. The rhythm accelerates when you inhale and slows when you exhale. Although some devices may adjust the contractions depending on body temperature or average respiratory rate over a certain period, they remain monotonous.
A team of scientists from Bristol and Batu Universities has described a more intelligent pacemaker that helps the heart return to its natural rhythm.
The device uses an analog chip onbased on a neural network that captures electrical signals that occur in the muscles of the chest with each breath. The system analyzes this information and adjusts the operation in real time, synchronizing the stimulation of the left atrium with breathing.
When testing the device in rats with heart failure, it increased the amount of pumped blood by 20%, compared with monotonous pacemakers.
Many advanced technologies are used in medicine. Earlier, we also reported on the development of artificial blood, which is suitable for patients with any blood type and can be stored for more than a year.</p>
