Cardiac arrhythmia refers to irregular heartbeats, which may cause fatigue and in severe cases, unconsciousness. To correct the heartbeats, an electrical pacemaker is often implanted. Yet there are several drawbacks of the device, including battery replacement, dislodging of the lead wire, and risk of infection. The size of the device is also not suitable for pediatric patients. Patients often require invasive surgery which leads to an even higher risk of infection. Researchers have developed a device-free pacemaker, using a small molecule to convert heart muscle cells to pacemaker cells to restore natural heart rhythm and create a minimally invasive treatment for both adult and pediatric patients.For more information:
