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 ...

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 ...

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 ...

The human heart rate is under the influence of various hormonal and neural control mechanisms. Normally, conduction of an electrical impulse through the heart begins at the sinoatrial (SA) node and ...

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 ...

NORTON, Va. - Every fifth of the month, we wear our red at News 5. It's part of our partnership with Wellmont Health System to keep you informed about the leading cause of death in women -- heart ...

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 ...

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 ...

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 ...

Adam Taylor is affiliated with the Anatomical Society. Your heart beats around 60 times a minute, delivering nutrients and removing waste from every cell in your body. It has been doing this since you ...

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 ...
