Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in ...

When a cardiac muscle cell contracts, the myosin filament pulls the actin filaments toward each other, which causes the cell to shrink. The cell uses ATP to power this contraction. A single myosin ...

Omecamtiv mecarbil represents the first medication that directly enhances heart muscle contraction. Phase 3 trials demonstrate modest benefits in specific patient populations with severe pumping ...

It plays a critical role in cardiac muscle contraction. In other words, it helps your heart beat. Normally, only a tiny amount of troponin can be detected in your bloodstream. But that changes if ...

Such effects have previously been demonstrated in whole animals, in perfused hearts and on isolated papillary muscles. Although a decision regarding the clinical usefulness of glucagon will — as ...

[2] Physicians interpreting dobutamine MRI stress tests must review the MRI images in near real time on special display software to assess heart muscle contraction or perfusion during drug infusion.

As the atria then relax, the ventricles in turn contract pumping blood to the lungs and to the rest of the body. The heart muscle contraction and relaxation phases are all made possible by electrical ...
