Researchers have developed an experimental wearable pacemaker that uses focused ultrasound to stimulate the heart without placing a device or electrical leads inside the body.
Their wearable system can identify the relevant region of the heart and direct focused ultrasound towards it.
In rats with abnormal heart rhythms, the researchers were able to use ultrasound stimulation to restore sinus rhythm.
