It starts in the ventricles, the heart's pumping chambers.</p> <h3>More to Know</h3> <p>Ventricular tachycardia occurs when electrical signals in the heart muscle are sent too quickly. This is often due to an underlying heart problem such as an enlarged heart (<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/az-cardiomyopathy.html/">cardiomyopathy</a>), heart valve disease, coronary artery disease, or <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hypertension.html/">high blood pressure</a>. Scar tissue that develops following a heart attack or heart surgery can also cause ventricular tachycardia, as can certain medications, electrolyte imbalances, recreational drugs, and other factors. In some cases the cause is unknown.</p> <p>In addition to heart palpitations, or feeling like the heart is racing, symptoms of ventricular tachycardia may include shortness of breath, chest pain, light-headedness and dizziness.</p> <p>Fainting, unconsciousness, cardiac arrest, and even death can occur when the heart rate is dangerously high or an episode of ventricular tachycardia lasts more than a few seconds. For this reason, it&rsquo;s important to call 911 or go to the emergency room for treatment if you see signs of ventricular tachycardia.</p> <h3>Keep in Mind</h3> <p>While ventricular tachycardia is a very serious condition, many people see improvement when the underlying condition can be managed.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
