By injecting a solution of nanoparticles around the heart, a temporary heart stimulator self-assembles, which can correct heart arrhythmia in emergency situations with the help of an external power source. After treatment, the electrode spontaneously disappears from the body. The study was conducted on animals.
Arrhythmia occurs when there are disturbances in the heart’s electrical signals, causing it to beat too fast, slow, or irregularly. Often, arrhythmia can be treated with medication, but it is also possible to alter the heart's rhythm using electrical signals with, for example, a defibrillator or surgically implanted pacemaker. These types of interventions can be challenging in war zones, during mountain hikes, or in other environments where a defibrillator is not available or surgery is not feasible.
"We have developed an injectable heart stimulator for emergency situations, which consists of a syringe loaded with a solution of nanoparticles," says Roger Olsson, Professor of Chemical Biology and Therapeutics at Lund University and Professor of Medicinal Chemistry at the University of Gothenburg.
