Matters of the heart are truly sensitive, especially when its electrical system is disrupted. This is also called an ...

It is characterised by an extra electrical connection in the heart. This extra pathway causes a "short circuit" which affects the heart's rhythm. While it can lead to tachycardia, this is not ...

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 ...

Researchers have uncovered a previously unknown molecular pathway that is critical to understanding cardiac arrhythmia and other heart muscle problems. Understanding the basic science of heart and ...

Researchers at the Fralin Biomedical Research Institute at VTC, collaborated on a new study revealing why low blood sodium ...

Learn critical heart skipping patterns that signal emergency situations. Recognize dangerous rhythm changes that demand immediate medical care.

Heart palpitations are usually harmless, but a rare condition of irregular heartbeat, or arrhythmia, known as Wolff-Parkinson-White syndrome, could cause problems.

When heart attacks damage critical electrical pathways or create large areas of dying tissue, they can trigger fatal arrhythmias leading to cardiac arrest. Conversely, not all cardiac arrests stem ...

Wolff-Parkinson-White (WPW) syndrome In this syndrome, a child has an additional electrical pathway in the heart, which causes the heart to beat faster than normal.

A pediatric cardiologist diagnosed Hudson had Wolff-Parkinson-White syndrome, which is caused when an extra electrical pathway in the heart makes a shorter loop, instead of the normal loop, from ...
