Ultrasound device for heartbeat regulation

Researchers from the Massachusetts Institute of Technology have developed a new technology for a pacemaker device that does not require surgical implantation. Instead, it can be worn externally and operates by stimulating the heartbeat using ultrasound waves from outside the body. The study demonstrated that this small device, about the size of a postage stamp, can reliably regulate heartbeats and restore the heart's natural rhythm over a follow-up period of eight months. This represents an advancement in the treatment of arrhythmias and could reduce patients' reliance on surgically implanted devices. The device employs acoustic genetics technology, which causes heart cells to respond to ultrasound waves, enabling non-invasive control of heart rhythms. While clinical applications are still in the preclinical stage, this technology promises a future where wearable, non-surgical pacemakers could be available, capable of targeting heart tissue with precise therapeutic effects and ensuring high safety.
