Although it can work with hearts of all sizes, the pacemaker is particularly well-suited to the tiny, fragile hearts of newborn babies.

When the pacemaker wires were later removed, Armstrong suffered internal bleeding — an outcome more common than many patients realize. Now, engineers at Northwestern University have developed what ...

Meanwhile, the current standard for temporary pacemakers in adults also presents difficulties. Most procedures involve surgeons sewing electrodes directly onto the heart, then attaching those ...

The sinus node refers to the heart’s natural pacemaker. This prevents the heartbeat from originating in the sinoatrial node, which creates sinus rhythm. Instead, it causes it to originate in ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can ...

A light-activated pacemaker dissolves in the body after use, offering safer, wireless heart care - especially for newborns ...

Generally, pacemakers are put in because the heart is going too slowly for one of two reasons. The first is that the heart's natural pacemaker - an area known as the sinus node which generates the ...

The world’s tiniest pacemaker — smaller than a grain of rice — could help save babies born with heart defects, say scientists. The miniature device can be inserted with a syringe and ...

The new device is smaller than a grain of rice and gets absorbed by the patient’s body when it’s no longer needed, ...

When the device on the chest detects irregular heartbeats it emits pulses of light into the chest that activate the pacemaker, delivering electrical stimulation to the heart. The device is ...

Traditional temporary pacemakers involve a tangle of ... Using light pulses, they changed the contraction of two heart chambers to match a natural beat. “You can pace the heart in very ...
