These electrical waves, when irregular, are thought to underly serious conditions such as fibrillation, where the heart fails to pump blood effectively. The research provides a way to predict the ...

Researchers from Durham University have made an exciting discovery that could improve how doctors treat dangerous heart rhythms, like those seen in cardiac arrest. Their work offers a way to ...

Through the pulse, the heart sends energy in the form of a blood pressure wave. Researchers have seen that changes in the electrical activity of brain cells occur in relation to the changes in the ...

Developed by Northwestern Engineering’s Igor Efimov and George Washington University’s Luyao Lu, the implantable device uses ...

A junctional rhythm occurs when the electrical activation of the heart originates near or within ... originates at or near the AV node, the P wave is frequently not seen; it can be buried within ...

A combination of the Q wave, R wave and S wave ... The QRS duration will lengthen when electrical activity takes a long time to travel throughout the ventricular myocardium.

To develop the new method, the team first engineered an array of nanoscale, needle-shaped electrodes. These electrodes, each up to 200 times smaller than a single heart muscle cell, are made of ...

Electrocardiogram tests – which measure the heart's electrical activity – could someday be paired with an artificial ...
