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 ...

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 ...

It is still elusive to what extent interactions between different cell types of the heart influence the normal heart rhythm and possibly trigger life-threatening arrhythmias. A new measurement method ...

Defibrillators and pacemakers help the heart maintain a regular rhythm. Defibrillators deliver a shock if the heart goes into arrhythmia. Pacemakers use electrical impulses to keep the heart from ...

Heart block is a disruption in the electrical signals that control your heart. Your heart depends on a steady flow of electrical signals that start in the heart’s upper chambers (atria). The signals ...

These days having both a land line and a mobile phone seems like overkill. But Virginia Tech researchers have shown that the heart relies on at least two key communication channels to keep abnormal ...

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 ...
