The rhythm in a working heart is regulated by electrical impulses. Disturbances of this bioelectrical process can result in cardiac arrhythmias, or irregularities in heartbeat -- a common ailment that ...

Reentry arrhythmia occurs when electrical signals in the heart deviate from their usual path, creating a loop that causes repeated stimulation and disrupts the heart’s rhythm. Symptoms of reentry ...

People with third degree heart block have an irregular heartbeat due to a total blockage of the electrical impulses that control the heart’s activity. It can lead to faintness and breathing difficulty ...

In order for the heart to do its work of pumping oxygen-rich blood to the body, it needs a trigger or electrical impulse to generate a heartbeat. This electrical impulse originates from the sinus node ...

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 ...

WASHINGTON, July 13, 2021 -- The rhythm in a working heart is regulated by electrical impulses. Disturbances of this bioelectrical process can result in cardiac arrhythmias, or irregularities in ...

A heart shock may restore the heart’s rhythm and is a potential treatment for atrial fibrillation (AFib). Doctors also refer to heart shock as electrical cardioversion. In AFib, a person has an ...

Led by Rob Gourdie, a professor at VTCRI, the international team of scientists revealed how electrical impulses might travel through heart muscle in steps, jumping between cells in a rapid, almost ...

Complete heart block means that there’s a complete separation of electrical activity between the upper and lower chambers of the heart. Without prompt medical attention, it can be fatal. Your heart ...

The automaker has developed a car seat with six sensors that detect electrical impulses generated by the heart without touching the driver's skin. Ford says data from the sensors can be read by the ...

Researchers provide an update on how electrical impulses in the heart travel from cell to cell. The connections between cells forming the low resistance pathway and facilitating the current flow are ...
