Re-entry ventricular arrhythmia

Re-entry Ventricular Arrhythmia

Re-entry ventricular arrhythmia (pronunciation: ree-en-tree ven-trik-yuh-lar uh-rith-mee-uh) is a type of cardiac arrhythmia that occurs in the ventricles of the heart.

Etymology

The term "re-entry" refers to the abnormal electrical circuit that forms in the heart, causing the arrhythmia. "Ventricular" refers to the ventricles, the lower chambers of the heart, and "arrhythmia" is derived from the Greek words "a-", meaning "not", "rhythmos", meaning "rhythm", and "-ia", a suffix used to indicate a condition. Thus, "arrhythmia" means "no rhythm", indicating the irregular heartbeat characteristic of this condition.

Definition

Re-entry ventricular arrhythmia is a condition where the electrical signals in the heart's ventricles become disorganized, leading to rapid and irregular heartbeats. This can cause the heart to pump less effectively, leading to symptoms such as dizziness, shortness of breath, and potentially, cardiac arrest.

Causes

Re-entry ventricular arrhythmia can be caused by various factors, including heart disease, heart attack, cardiomyopathy, and certain medications. It can also occur in individuals with structurally normal hearts.

Symptoms

Symptoms of re-entry ventricular arrhythmia can vary depending on the severity of the condition. They may include palpitations, dizziness, fainting, shortness of breath, and chest pain. In severe cases, it can lead to cardiac arrest.

Treatment

Treatment for re-entry ventricular arrhythmia typically involves medications to control the heart rate or rhythm, and in some cases, procedures such as catheter ablation or the implantation of a cardioverter defibrillator.
