Determination of right ventricular dysfunction using the speckle tracking echocardiography method in patients with obstructive sleep apnea

Abstract

Subclinical RV dysfunction can be established in OSA patients even in the absence of pulmonary hypertension and pathologies which could have adverse effects on RV functions. In addition to the methods of conventional, Doppler and tissue Doppler echocardiography, using the STE method can determine RV dysfunction in the subclinical phase.
