What is Dyssynchronous?

What is Dyssynchronous?

Introduction. Mechanical dyssynchrony describes the differences in the timing of contraction or relaxation between the left ventricular (LV) and right ventricular (RV) (interventricular dyssynchrony), or between different myocardial segments of the LV (intraventricular dyssynchrony).

What is septal dyssynchrony?

Septal flash, also known as septal beaking, is a sign of interventricular dyssynchrony seen on echocardiography or cinematographic cardiac CT/MRI. It represents an abnormal rapid movement pattern of the interventricular septum during pre-ejection systole (i.e. isovolumic contraction):

How serious is ventricular dyssynchrony?

Ventricular dyssynchrony is a serious medical condition and should be evaluated by a medical professional. There are a number of treatment options available that can help improve the lives of people with ventricular dyssynchrony.

What is the treatment for ventricular dyssynchrony?

Ventricular dyssynchrony is first treated with medications to help the heart pump more effectively, such as a class of medications called beta-blockers. In addition, cardiac resynchronization therapy, which uses a cardiac pacemaker, may be used to treat dyssynchrony.

What does it mean when the bottom of your heart is not working?

When the lower chambers of the heart, the ventricles, do not pump at the correct time or are out of sync, the condition is called ventricular dyssynchrony. There are three main types of ventricular dyssynchrony: Atrioventricular dyssynchrony – affecting the contraction between the atrium and ventricle.

What is patient ventilator dyssynchrony?

Ventilator dyssynchrony is defined as the inappropriate timing and delivery of a mechanical breath in response to patient effort and may cause VILI. Such deleterious patient–ventilator interactions have recently been termed patient self-inflicted lung injury.
