There are two types of ventricular arrhythmias, ventricular tachycardia (VT) and ventricular fibrillation (VF). In ventricular tachycardia the bottom parts of the heart (the ventricles) are beating very fast. You may not be able to feel a pulse because the heart does not pump blood well when only the lower chamber is beating.
If not treated, ventricular tachycardia may go into what is known as ventricular fibrillation. VF can also occur by itself. In VF, the ventricles "quiver" or "twitch." The heart does not pump blood to the body. You will not be able to feel a pulse in someone in VF.
What Causes Ventricular Arrhythmia?
Many times, it may not be possible to find a cause. Some possible causes: Some types of heart disease, caffeine, alcohol, tobacco, diet pills, or certain prescribed and OTC medications (check with your doctor) and occasionally after open heart surgery.
What Could Happen if Left Untreated?
Ventricular tachycardia and ventricular fibrillation are both serious and need to be treated immediately.
Is there Testing for Ventricular Arrhythmia? Your doctor may suspect a problem by your description of the symptoms you have. They may diagnose the problem by seeing abnormal beats on a heart monitor, an EKG or stress test or an electrophysiology study.
What is the Treatment
for Ventricular Arrhythmia?
It is likely that your doctor will want you to have Electrophysiology Studies (EPS). More than one may be needed. The goal of the EPS test is to try to find medication that will work to prevent your arrhythmia. Other treatments are also available. Your doctor will discuss these with you when and if they should be needed.
What Happens After
Diagnosed and go Home?
Some people with heart problems may have to limit their activities. Your doctor and nurse will explain any activity restrictions before you go home.
