Can psvt cause sleep apnea?

No: Obstructive sleep apnea (osa) is a condition of cessation of breathing during sleep. It is due to obstruction of the oropharyngeal airway usually at the level of the tongue or epiglottis. Two-thirds of patients with osa are overweight and fatty infiltration of the neck and tongue may also contribute to airway obstruction during sleep. Rec. See sleep specialist for a sleep study (psg).
