Tachycardia is a rapid heartbeat over 100 beats per minute. Ventricular Tachycardia is something more. It is an abnormal rhythm, the most dangerous form precluding Ventricular Fibrillation that almost always leads to Cardiac Arrest. Ventricular Tachycardia occurs when the heart is in Tachycardia and the rhythm is disturbed by electric impulses, causing the lower chamber “beat” to contract too quickly, not allowing enough blood to enter the bottom chamber, or pump out with fully efficiency. This quick and loosened beat reduces blood flow and can cause dizziness, chest pain, loss of breath and syncope (passing out). When this beat occurs in singular form, it is called a PVC. When it occurs in a run of many it is called Ventricular Tachycardia. Ventricular Tachycardia is the most dangerous cardiac rhythm because it can convert to Ventricular Fibrillation. When this occurs, the rapid beats turn to a quivering chaos wherein the heart has no rhythm at all and if it is not “shocked,” (electroshock) or “slammed” (literally, by the hard hit of fist to the chest) it will end in cardiac arrest and death.

What are the major types of arrhythmia?
Atrial Fibrillation, Ventricular tachycardia, Ventricular fibrillation, Supraventricular tachycardia
What is the prognosis for ventricular tachycardia?
With appropriate drug or surgical treatment, ventricular tachycardia can be controlled in most people.
What is the physiology of ventricular tachycardia?
A rapid heart rate can originate in either the left or right ventricle. Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia
What does nonsustained ventricular tachycardia mean?
Nonsustained ventricular tachycardia is elevated heart rate originating in the ventricles that stops on its own.
How can ventricular tachycardia be prevented?
A person susceptible to sustained ventricular tachycardia often has a small abnormal area in the ventricles that is the source of the trigger event.
How can I tell if I have ventricular tachycardia?
There are certain symptoms of ventricular tachycardia that can help physicians diagnose it including palpitations and dizziness. You should see a doctor.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
Is ventricular tachycardia a type of abnormal heart rhythm?
Ventricular tachycardia is an abnormal heart rhythm in which the heart beats rapidly due to electrical stimulation coming from the ventricle.
Would alpha blocker alleviate ventricular tachycardia?
No, alpha blockers would not alleviate ventricular tachycardia. However, it can be used in combination with other treatments to help in the alleviation of such.
What treatments are available for ventricular tachycardia?
Ventricular tachycardia is a dangerous disease and that person should be transported to an ED immediately. Emergency medical technicians will have to provide defibrillation and supplemental oxygen.
How is ventricular tachycardia diagnosed?
Diagnosis is easily made with an electrocardiogram
What does the medical abbreviation VT mean?
Ventricular tachycardiaventricular tachycardia
