Scientists have created an intelligent bionic pacemaker that causes the heart to fight natural rhythm, increasing blood pumping efficiency.
Currently applied pacemakers cause reductions with a constant frequency, but the work of a healthy organ depends on respiratory. Rhythm accelerates when inhaling and slows down when exhaling. Although some devices can adjust the reduction time depending on the body temperature or the average respiration rate for a certain period, but they remain monotone.
The team of scientists from Bristol and Bat universities described a smarter pacemaker who helps the heart to return the natural rhythm.
The device uses an analog chip based on a neural network, which captures electrical signals arising in the muscles of the chest at each breath. The system analyzes this information and adjusts real-time operation, synchronizing the stimulation of the left atrium with breathing.
When testing the device on rats with heart failure, it raised the amount of blood pumped by 20% compared with monotonous pacemakers.
