My recent ekg states slight inferior repolarization disturbance, consider ischemia, LV overload or aspecific change . I am 62 years old, female, amlodipine and HCTZ for BP, and synthroid. very active worker. No chest pain or SOB. Was wondering if this LV overload could have anything to do with sleep apnea. I have never been checked. Don t wake up gasping but I sleep an average of 3 to 4 hours straight. Some times I feel more rested after 3 to 4 hours then going back to bed and sleeping another 3 to 4 hours.
