MIT engineers have developed a noninvasive pacemaker that stimulates the heart using ultrasound. The design could one day ...

Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically generates 60 ...

Regulating a misfiring heart has long required surgeons to permanently embed metal wires and batteries deep inside a ...

Scientists have designed a temporary, battery-free pacemaker that can be broken down by the patient’s body when its work is done, the latest advance in the emerging field of bioelectronics. In a paper ...

With heart failure, the heart becomes enlarged and its electrical systems become stretched. This interferes with how the parts of the heart coordinate to contract and pump blood, making it inefficient ...

Aug. 4 (UPI) --Researchers in China have developed a battery-less cardiac pacemaker that runs on energy derived from the heart, they said Wednesday during a presentation at the AIP Publishing Horizons ...

CHICAGO — One person’s used pacemaker is another person’s treasure. A program to refurbish used pacemakers could expand access to the lifesaving devices. In a clinical trial of nearly 300 people, ...

Your heart's job is to keep your pulse steady to pump blood throughout your body. Sometimes your heart rate is slower when you're relaxing, and sometimes it's faster when you're exercising or stressed ...
