[Nocturnal heart rate variation in patients with sleep apnea syndrome]

We observed a group of 10 patients with OSA symptoms. In all of them we investigated: the first examination-MESAM 4, EKG, UKG, lung function test, polysomnography. Analyzed the results we regard to appear of the heart rate changes in relation to apnea type, saturation and sleep phases. The results showed, that: 1. The altitude of snoring index is not adequate to the changes of heart rate and altitude of saturation (MESAM 4). 2. Apnea index and desaturation are conformed to heart rate changes (polisomnography). 3. Heart rate changes and desaturations are independent to sleep phases. 4. Heart rate changes and desaturations are independent to apnea type.
