Jun 2, 2022 · Monomorphic ventricular tachycardia is a type of irregular heart rhythm (arrhythmia) that happens when the lower chambers of your heart beat at a dangerously fast pace. It can turn into a dangerous — or even deadly — problem depending on how and when it happens.
Mar 19, 2023 · 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.
3 days ago · Monomorphic ventricular tachycardia is an irregular heartbeat where the bottom chambers of your heart beat quicker than usual. It can cause symptoms such as shortness of breath, dizziness, or fatigue.
In monomorphic ventricular tachycardia, the shape of each heart beat on the ECG looks the same because the impulse is either being generated from increased automaticity of a single point in either the left or the right ventricle, or due to a reentry circuit within the ventricle.
Ventricular tachycardia may be monomorphic or polymorphic and nonsustained or sustained. Monomorphic VT: Single abnormal focus or reentrant pathway and thus regular, identical-appearing QRS complexes. Polymorphic VT: Several different foci or pathways and thus irregular, varying QRS complexes. Nonsustained VT: Lasts < 30 seconds.
May 20, 2024 · Sustained monomorphic ventricular tachycardia (SMVT) is defined by the following characteristics: A regular (<50 msec beat-to-beat cycle length variation) wide QRS complex (≥120 milliseconds) tachycardia at a rate greater than 100 beats per minute. The consecutive beats have a uniform and stable QRS morphology.
Monomorphic ventricular tachycardia (VT, VTach). P-waves are visible but they do not have any relation to the QRS complexes. This situation is referred to as “AV dissociation” and indicates that atrial and ventricular activity and independent.
Mar 6, 2024 · Ventricular tachycardia is a type of irregular heartbeat, called an arrhythmia. It starts in the lower chambers of the heart, called the ventricles. This condition also may be called V-tach or VT. A healthy heart typically beats about 60 to 100 times a minute at rest.
Jul 30, 2023 · Ventricular tachycardia in the presence of acute coronary syndrome is usually polymorphic, while the monomorphic VT is a characteristic feature of myocardial scar-related reentry. Ventricular tachycardia predicts a higher risk of death after acute myocardial infarction.
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.
