What is ventricular tachycardia?

Ventricular tachycardia. In ventricular tachycardia, the electrical impulses fire too quickly from your ventricles, causing blood to be pumped out faster than usual. Your ventricles may not have enough time to fill up properly with blood and this can sometimes cause your heart to stop pumping blood around your body (cardiac arrest).


If the attack lasts for 30 seconds or more, it’s called sustained ventricular tachycardia. Ventricular tachycardia can progress to a condition called ventricular fibrillation.

What is ventricular tachycardia?

See details. This is a rapid heartbeat which originates in the ventricles of the heart. This can be potentially life-threatening because it may lead to ventricular fibrillation. Read more...

Ventricular tachycardia is what?

See below. Normal heart rhythm arises in specialized cells within the right atrium called the sinus node and then is propagated over specialized conducting tissue into both ventricles. When an irritable focus in a ventricle begins firing independently repeatedly or in a repetitive loop, initiating it's own renegade rhythm at a rapid rate, it's called ventricular (where it starts) tachycardia (rate >100).

VT. Ventricular tachycardia (VT) is a fast heart rhythm that originates in the bottom two chambers of the heart. It can result in palpitations, chest pain, shortness of breath, dizziness, passing out, and even death. It is rare unless you've had a heart attack or heart failure/cardiomyopathy. Treaments can include ICD's, ablation procedures, or medicine. Discuss with a heart rhythm specialist. Read more...

Ventricular tachycardia managment?

Various. Depends on the severity of the v tach, and your underlying heart condition. Medications such as the Cordarone (amiodarone) you are taking will often control it. In some cases the arrhythmia is treated with an ablation, an invasive procedure performed in a cath lab. Discuss with your cardiologist. Read more...
Ep. This is a serious condition and you must see an electrophysiologist. If normal heart, it is possible at your age to manage with medication but often can have an ablation and cure it. Read more...

Are the symptoms of ventricular tachycardia bad?

Yes! Ventricular tachycardia is usually fatal. It can be treated by defibrillation (that maneuver you see done on tv when the rub gel on the paddles and yell "clear!" then shock the patient). Only if caught in the first few seconds is v-tac (as we call it for short) reversible, and even then the underlying cause must be determined and fixed so it doesn't dome back. Read more...

How do you treat ventricular tachycardia and long q-t syndrome?

VT, long QT. As usual this is far too complcated for the space here. You need an etiologic diagnosis for the arrhythmia and an estimate of the type of long QT syndrome present. There are several genotypes of long QT. Once this is done, there are drugs, electrophysiologic testing/therapy and device therapy all possible as well as anatomic or physiologic therapy depending on what is thought to be the cause.

What is the definition or description of: ventricular tachycardia?

VT. Ventricular tachycardia refers to rapid regular beats originating from the cells in the bottom of the heart and usually indicates a problem with the heart muscle, although not always. Short episodes referred to as non-sustained ventricular tachycardia, can be asymptomatic. Longer episodes often are symptomatic and can be life threatening. Read more...
