What is outflow tract VT?

Overview. Right ventricular outflow tract (RVOT) tachycardia is a form of monomorphic VT originating from the outflow tract of the right ventricle or occasionally from the tricuspid annulus. It is usually seen in patients without underlying structural heart disease.

What is LV outflow tract?

The left ventricular outflow tract (LVOT) is considered represent the region of the left ventricle that lies between the anterior cusp of the mitral valve and the ventricular septum. Its dimensions are often recorded in TAVI work up studies.

What does VT mean in anesthesia?

Here a target breathing volume (VT) is set and the necessary pressure for it applied. Every detected inspiration attempt at PEEP level triggers a pressure-supported, flow-cycled breath. If the lung mechanics change, the applied pressure varies to keep the set VT constant.

What is LV outflow tract obstruction?

Left ventricular outflow tract obstruction (LVOTO) is a recognised feature of hypertrophic cardiomyopathy. It is caused by the thickened heart muscle and the abnormal movement of the mitral valve. This is the main mechanism of debilitating symptoms in hypertrophic cardiomyopathy patients.

Can ventricular tachycardia be benign?

VT that occurs in a structurally normal heart can be benign if it stops on its own. Any heart condition that results in damage and scar to ventricular muscle can produce VT. It also be caused by an inherited arrhythmia such as long QT syndrome or Brugada syndrome.

Is Lvot life threatening?

The onset of LVOTO is largely unpredictable due to a complex interplay between preload, afterload, heart rhythm and rate in susceptible patients. The consequences of missing this treatable condition may lead to life-threatening hypotension refractory to, or exacerbated by, a further increase in inotropic support.

What is the normal left ventricular outflow tract gradient?

LVOT obstruction is defined as a peak instantaneous gradient greater than or equal to 30 mm Hg. A gradient greater than or equal to 50 mm Hg is generally recognized as the threshold at which LVOT obstruction becomes hemodynamically significant.

What is VT on ventilator?

When AC mode is selected in the ventilator, four parameters may be quickly modified: Tidal Volume (VT) This is the set amount of volume that will be delivered with each breath.

What is the most common cause of obstruction to left ventricular inflow?

Most cases of LVOTO in newborns and children are congenital, whereas in adults the cause may be a bicuspid aortic valve or degenerative aortic stenosis. In almost all cases, symptomatic patients need surgery because the obstruction is mechanical.

What is the best treatment for ventricular tachycardia?

If you have ventricular tachycardia, you may be given medications called anti-arrhythmics by mouth or IV to slow the fast heart rate. Other heart medications, such as calcium channel blockers and beta blockers, may be prescribed with anti-arrhythmic drugs.
