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. Regular, broad complex tachycardia.
Learn all about ventricular tachycardia (VT), with emphasis on ECG features, causes, clinical characteristics, differential diagnosis and treatment.
Ventricular Tachycardia = 3 or more VEB at a rate of > 130 beats/min. If > 30 seconds = sustained; can be monophoric or polymorphic.
Test results also can help determine if another health problem is causing V-tach. Electrocardiogram (ECG or EKG). This is the most common test to diagnose tachycardia. An ECG shows how the heart is beating. Small sensors, called electrodes, attach to the chest and sometimes the arms and legs.
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.
Figure 7.12 EKG tracing illustrating a run of ventricular tachycardia (V-tach), characterized by a series of wide QRS complexes. [12] Sustained Ventricular Tachycardia. When more than 30 consecutive beats are PVCs with a rate >100 bpm, it is known as sustained ventricular tachycardia. R-on-T Phenomenon
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...
Electrocardiography (ECG) Diagnosis of ventricular tachycardia is by ECG (see figure Broad QRS Ventricular Tachycardia). Any wide QRS complex tachycardia (QRS ≥ 0.12 second) should be considered VT until proved otherwise.
Ventricular tachycardia is defined as a sequence of three or more ventricular beats. The frequency must by higher than 100 bpm, mostly it is 110-250 bpm. Ventricular tachycardias often origin around old scar tissue in the heart, e.g. after myocardial infarction. Also electrolyte disturbances and ischemia can cause ventricular tachycardias.
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 by type. Several types of VT, including Monomorphic, Polymorphic and Torsade de Pointes are available for review on this website.
