Overview

Echocardiography or ultrasound are not used in the diagnosis of sleep apnea. Cor pulmonale and pulmonary hypertension may be evident in patients with severe sleep apnea in echocardiography.

Sleep Apnea Echocardiography or Ultrasound

• Echocardiography or ultrasound are not used in the diagnosis of sleep apnea
• Cor pulmonale and pulmonary hypertension may be evident in patients with severe sleep apnea in echocardiography, showing the following structural changes:

• Right ventricular dilatation
• Abnormal flattening of the interventricular septum
• Right atrial enlargement
