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 ...

Second-degree heart block is a type of heart rhythm disorder. There are two types of second degree heart block — Mobitz type 1 and Mobitz type 2. Mobitz type 2 heart block occurs when the electrical ...

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 ...

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 ...

Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart -; a discovery ...

Dear Dr. Roach: My husband had a stress test done several years ago, and at the time, it was discovered that he had a bundle branch block in his heart. No one mentioned it until recently, after he had ...

Dear Dr. Roach: I recently had an EKG that showed first-degree heart block and “inferior infarct, age undetermined.” What does that mean? What should I do to make sure it doesn’t get worse? I will be ...

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 ...
