Heart rhythm problems occur when heart muscle cells fail to properly transmit electrical signals that coordinate blood pumping. Now, scientists at Duke University have devised a promising method to ...

Electrical problems in the heart can often lead to serious and fatal complications including complete heart block or heart failure. Left ventricular conduction disease occurs when there is an ...

Heart conduction disorders can often lead to serious or fatal complications including complete heart block or heart failure. Left ventricular conduction disease occurs when there is an electrical ...

The heart is a natural pump made of muscle tissue, and, like every muscle, it needs energy to function. The heart’s pumping action is regulated by an electrical conduction system that coordinates the ...

New research explains how low levels of the electrolyte sodium in the blood can disrupt the timing of the heartbeat in patients taking widely used rhythm-control medications such as flecainide, which ...
