Hi TRey and Welcome!!,
Unfortunately you have succumbed to the common stereotypic myth. You don't have to be overweight, out of shape or even snore to have sleep apnea. It affects all sizes, ages and fitness levels (I do triathlons). That misconception, which many in the medical profession still hold on to, is responsible for thousands of people being misdiagnosed (including myself) with devastating consequences to their health. So there is no classic type.
Also apnea is very frequently associated with arrhythmias. I have Premature Atrial Contractions when I am not treated, my brother has PACs and atrial fib.
The Cardiovascular and Metabolic Effects of Sleep Apnea
Additionally, we had a forum member nearly die from his OSA induced arrhythmias. Harley was featured on TLC's "Mystery Diagnosis" program. Of course, all of us with apnea knew what it was.
Personal Stories
So I would highly recommend that you have a sleep study done. I would also highly recommend that, should you have apnea, you are seen by a physician who has an accreditation in sleep medicine. They are the best people to diagnose, treat and follow you.
Keep us posted on your progress!!
Vicki
