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 ...

Scientists have successfully transformed guinea-pig heart-muscle cells into pacemaker cells, paving the way for a biological alternative to artificial pacemakers. Pacemaker cells generate electrical ...

FAILURE of the myocardium to respond to an electronic pacemaker with implanted electrodes, because the threshold to electric stimulation is abnormally high, is known to occur occasionally. 1, 2 In all ...

Today's pacemakers are about the size of a small matchbox, and future models are expected to shrink even further, becoming smaller than a grain of rice. Now, these devices, depending on the model, can ...

The heart's regular rhythm is crucial to the delivery of oxygenated blood and nutrients to all the organs of the body. It is regulated by a bundle of cells called "the pacemaker," which use electrical ...

The CResPace project is developing a new pacemaker that works in conjunction with small artificial neural networks to better adapt to the demands of the body—replicating a healthy heart When the heart ...

We are at a critical time and supporting science journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen scientific ...

A specific cell population is responsible for ensuring that our heartbeat remains regular. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have now elucidated the mode of action of ...

Sick sinus syndrome (SSS) is a heart rhythm problem that affects your heart's natural pacemaker. You may develop symptoms of SSS like dizziness, fainting, and fatigue. Treatment may include lifestyle ...

Scientists have created an artificial fish that can swim on its own using human heart cells, bringing researchers one step closer to developing a more complex artificial muscular pump. According to ...
