Ventricular tachycardia (VT) means that your lower chambers beat fast yet insufficiently. This is usually due to abnormal electrical circuits in the ventricular muscles. The term "monomorphic" comes from how this heart rhythm appears on an electrocardiogram (often shortened using one of two abbreviations, ECG or EKG).

2024年10月8日 · Definition, mechanism, and clinical significance of ventricular tachycardia (VT). Typical ECG findings with examples of monomorphic VT

MVT is characterized as a wide complex tachycardia with a stable cycle length and consistent beat-to-beat QRS morpho-logy. Differentiation of MVT from SVT with aberrancy is best done by the demonstration of AV dissociation, either by evident P waves that are dissociated from the QRS complexes or by the presence of capture or fusion beats ( Fig ...

2023年2月14日 · Polymorphic ventricular tachycardia (PVT) and Monomorphic ventricular tachycardia (MVT) are both types of ventricular tachycardia (VT), which is a fast heart rhythm originating from the ventricles. The key difference between PVT and MVT is that PVT is characterized by a constantly changing QRS complex, while MVT has a consistent QRS complex.

Using ECG features to hypothesize the underlying mechanism of a VT, which involves examining the initiation and termination. How to localize the source of the VT using a 12- or 15-lead ECG. This means finding the location of the ectopic focus in automatic VTs and the exit site of the reentry circuit in a reentrant VT.

2004年2月1日 · We investigated the clinical and electrophysiological features of monomorphic ventricular tachycardia (MVT) with different initiation patterns in patients with implantable cardioverter defibrillator to assess whether there is a relationship between the initiation patterns of sustained MVT and clinical characteristics, and the efficacy of ...

1995年8月1日 · ECG recordings showing ablation of repetitive monomorphic ventricular tachycardia (VT) originating from the left ventricle (patient 5). Surface leads I, aVF, and V 1 are shown, along with a local electrogram from the right ventricular apex (RVA).

2022年11月10日 · This article is a guide for interpreting abnormal Ventricular Tachycardia EKGs, including qualifying criteria and a sample EKG rhythnm strip. Ventricular tachycardia (VT) is a rapid heartbeat over 100 bpm that originates in the ventricles. The EKG will show three or more irregular heartbeats in a row. Ventricular tachycardia can be classified ...

ECG can help in identifying MMVT by demonstrating a wide QRS tachycardia with a constant morphology that originates from the ventricles. MMVT usually presents with a faster heart rate and regular rhythm than sinus rhythm. The electrocardiogram recordings need to be analyzed carefully to differentiate MMVT from other ventricular tachycardias.

2020年11月4日 · Textbooks of medicine and cardiology as well as guideline documents and position papers describe palpitations as a common symptom of ventricular tachycardia (VT). However, data to support this description are lacking. The aim of our study was to evaluate the symptomatology of sustained monomorphic VT with emphasis on the prevalence of palpitations.
