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

Oct 8, 2024 · ECG features increasing the likelihood of VT. Electrocardiographic features that increase the likelihood of VT include: Absence of typical RBBB or LBBB morphology. Extreme axis deviation (“northwest axis”): QRS positive in aVR and negative in I and aVF. Very broad complexes > 160ms. AV dissociation: P and QRS complexes at different rates

Learn all about ventricular tachycardia (VT), with emphasis on ECG features, causes, clinical characteristics, differential diagnosis and treatment.

Nov 3, 2020 · Ventricular Tachycardia = 3 or more VEB at a rate of > 130 beats/min. If > 30 seconds = sustained; can be monophoric or polymorphic.

Jul 30, 2023 · A 12-lead ECG in sinus rhythm helps diagnose the underlying cause of ventricular tachycardia, e.g., myocardial ischemia/infarction, long QT syndrome, hypertrophic cardiomyopathy, Brugada syndrome, and arrhythmogenic right ventricular cardiomyopathy.

Ventricular tachycardia can occur due to coronary heart disease, aortic stenosis, cardiomyopathy, electrolyte imbalance, or a heart attack. [2][3] Diagnosis is by an electrocardiogram (ECG) showing a rate of greater than 120 beats per minute and …

In this review, we discuss the definition of VT, review features of wide-complex tachycardia (WCT) on ECG that might be helpful in diagnosing VT, discuss the different substrates in which VT can occur and offer brief comments on management considerations for patients found to have VT.

Ventricular tachycardia refers to a wide QRS complex heart rhythm — that is, a QRS duration beyond 120 milliseconds — originating in the ventricles at a rate of greater than 100 beats per...

Learn about ECG features of Ventricular Tachycardia, including mechanisms, causes, duration, hemodynamics, and key morphology indicators.

Mar 25, 2025 · Obtain a new baseline ECG to identify signs of an underlying cardiac condition or conduction abnormality associated with episodic VT. Consider further laboratory studies or imaging to identify underlying causes based on clinical suspicion and ECG findings.
