What Causes Fluctuation In Heart Rate?

Hi, my O2 saturation is in the low 90's at rest, but drops to the low 80's with standing or mild exertion. My heart rate is in the 60-70 bpm range at rest, but jumps up to over 100 bpm with standing. I feel SOB with exertion and have been given a Xopenex inhaler, which provides some relief. This has been particularly noticeable for the last 4-5 months, but I don't know how long I've had the problem. I'm 57, overweight (190 lbs./5'6"), but work out very vigorously in water aerobics 3 times a week (for many years).I underwent a thorough battery of both pulmonary and cardiac testing, with no other abnormal results. I am a former smoker who quit 20+ years ago. I have also been diagnosed with sleep apnea and have had O2 sat's as low as 70 while asleep. Help!

so in short you are suffering from Chronic obstructive airway disease, obstructive sleep apnea and Postural orthostatic tachycardia syndrome. For OSA you should try to lose weight, healthy lifestyle and cpap therapy will be helpful. For COPD u should quit smoking and yoga will be helpful. Also home based oxygen therapy if your saturation is Persistently low. while your tachycardia is probably related sympathetic activity due to OSA. so above mentioned therapies will probably help you.
