Obstructive sleep apnea syndrome

Of special interest to us are the electro-anatomical origins of atrial supraventricular extrasystoles in patients with paroxysmal atrial fibrillation induced through variations in intrathoracic pressure. These fluctuations in thoracic pressure occur more frequently at night in patients who suffer from obstructive sleep apnea syndrome. In another study, we are assessing the impact of obstructive sleep apnea on the thoracic aorta.

Additionally, our department performs epidemiological studies where the prevalence of obstructive sleep apnea in patients with Ehlers-Danlos Syndrome is assessed.

If you are interested in participating in a research project, we would be pleased to send you more detailed information. Please feel free to contact us anytime at the address provided.
