Ventricular Arrhythmia Overview

What is a ventricular arrhythmia?
A person with a ventricular arrhythmia has an abnormal heart rate or abnormal heart rhythm. An electrical impulse stimulates the muscle fibers in the heart to contract in a very organized manner. Any abnormality or disturbance in the impulse can result in a cardiac arrhythmia. A ventricular arrhythmia is caused by abnormal electrical impulses in the lower chambers of the heart, called the ventricles.

What are the symptoms of a ventricular arrhythmia?
The most common symptom of ventricular arrhythmia is palpitations. Additional symptoms of a ventricular arrhythmia include chest pain, dizziness, faintness, fainting, difficulty breathing, and excessive sweating.

How does the doctor treat a ventricular arrhythmia?
Treatment for a ventricular arrhythmia may include medication, a pacemaker, or surgery. Emergency treatment of a serious ventricular arrhythmia requires the application of electrical current to the heart.
