2024年10月8日 · Ventricular Tachycardia (VT) is a broad complex tachycardia originating from the ventricles. There are several different forms of VT — the most common is monomorphic VT, which originates from a single focus within the ventricles. ECG features of monomorphic VT
Polymorphic Ventricular Tachycardia: Terminology, Mechanism, …
2021年9月7日 · Polymorphic ventricular tachycardia (VT) is a malignant ventricular tachyarrhythmia with changing QRS pattern that will either terminate spontaneously (causing syncope if it lasts more than a few seconds) or will deteriorate to ventricular fibrillation (VF), causing cardiac arrest.
Ventricular tachycardia - Symptoms and causes - Mayo Clinic
2024年3月6日 · Ventricular tachycardia is caused by faulty heart signaling that makes the heart beat too fast in the lower heart chambers. The lower heart chambers are called the ventricles. The fast heart rate doesn't allow the ventricles to fill and squeeze to pump enough blood to the body.
