dyssynchrony

dyssynchrony

(dis-sing'kro-ne) [ dys- + synchrony]
Any disorder in the normal or expected coordination of timed events.

auditory dyssynchrony

Auditory neuropathy.

neuromechanical dyssynchrony

Any difference between the respiratory support provided to a patient by a mechanical ventilator and the patient's breathing. In neuromechanical dyssynchrony, the inspiration of the ventilator is typically longer than the patient's. This difference is referred to colloquially as “fighting the ventilator.”

patient-ventilator dyssynchrony

Failure of synchronous interaction between a patient's neurally controlled breathing and the timing of a mechanical ventilator.

Auditory dyssynchrony or auditory neuropathy: Understanding the pathophysiology and exploring methods of treatment.
Auditory dyssynchrony, also known as auditory neuropathy, is a condition where transmission of sound impulses including speech sounds is not in proportion or synchronous from the inner ear to the brain thus leading to interrupted sound signals leading to understanding problems in the individual.
Onset of left ventricular mechanical contraction as determined by phase analysis of ECG-gated myocardial perfusion SPECT imaging: development of a diagnostic tool for assessment of cardiac mechanical dyssynchrony.
sup][1] VPCs generally causes dyssynchrony with reduced ventricular contraction, leading to adverse ventricular remodeling and is detrimental to ventricular systolic function.
The presence of reversible perfusion defect may or may not alter the indices of mechanical dyssynchrony by phase analysis17.
Prevention and management of AV blocks and bradyarrhythmia are very important, because they cause AV dyssynchrony leading to loss of atrial contribution to ventricular filling further jeopardising already decreased cardiac output.
Electrical and mechanical components of dyssynchrony in heart failure patients with normal QRS duration and left bundle-branch block impact of left and biventricular pacing.

The pacemaker stimulation from right ventricular outflow tract (RVOT) provides stimulus conduction that enables the chamber activation from the septum to the rest of the myocardium which in turn gives less dyssynchrony and shorter QRS duration [2-4].
This may be because muscle relaxation provides superior transferring conditions, with less risk of patient-ventilator dyssynchrony and airway complications.
Cardiac resynchronization therapy (CRT) is widely used to treat chronic heart failure patients with electromechanical dyssynchrony and a deteriorating functional status [12].
