The heart health condition officials say caused Pennsylvania Sen. John Fetterman’s fall Thursday could have been deadly if it wasn’t immediately treated, according to cardiologists. And the first-term ...

Two days after a heart episode and fall that required hospital care, U.S. Sen. John Fetterman of Pennsylvania says he's had "a full recovery" from the incident and has been released, according to a ...

Researchers used an electrophysiological computer model of the heart's electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They ...

Depending on how the heart’s electrical activity appears on an EKG, a doctor may diagnose coarse or fine ventricular fibrillation (VF). Coarse VF appears as larger waves on an EKG compared with the ...

In a paper published this week in Chaos, by AIP Publishing, researchers from Sergio Arboleda University in Bogotá, Colombia, and the Georgia Institute of Technology in Atlanta used an ...

A computer model of the voltage field in a portion of the atria, with each box progressing in time up to 20 seconds after fibrillation begins. The authors discovered adjusting the duration and the ...
