I am a 39 yo female of normal weight - non smoker.  I had two cardiac ablations this spring/summer for AVNRT.  After the second ablation on 6/22/06, I started having Inappropriate Sinus Tach. and SOB.  I was put back on Inderal (which I had already taken for 25 years but was taken off after 2nd ablation).  I figured the tachycardia was causing the SOB but I was wrong. The tachy. has been under control. I continue to have SOB with minimal exertion and I frequently yawn/sigh because I feel I cannot get a deep breath. I have a dry cough often that seems to come from my throat/upper chest.  I am having very frequent PACs (did not have pre-ablation).  I also have to clear my throat often from mucous - especially after eating.  I do have a large "cold"thyroid nodule but my throid functions are normal.  I had a cardiac cath. on8/29/06 and all is clear.  I had pulmonary function test - normal and chest x-ray negative.  These symptoms have greatly impacted my life - I have become more sedentary and the "air hunger" is disturbing.  I do not feel this is due to anxiety but it is now causing me some anxiety.  I have constant fatigue and somedays cannot work.
1. What else can be tested/checked for?
2. Could it possibly be from phrenic nerve damage from cardiac ablation - problems started immed. after 2nd ablation??

I would appreciate your opinion and reply.  Thank you.

If the phrenic nerve were damaged, changes would be seen on the chest x-ray and your pulmonary function tests (PFTs) wouldn

Shortness of breath associated with mild exertion suggests phrenic nerve involvement. But your pulmonary tests and chest X-rays appear to rule out diaphragmatic paralysis.

The use of a pulse-oximeter to record your blood-oxygen levels during the day would be helpful. These use-at-home instruments are somewhat expensive. But you might be able to obtain one for temporary use.

Also, an overnight sleep study is suggested to rule out sleep apnea as a contributor to day time fatigue. A use-at-home device is also available for this purpose.

The analysis of changes in blood-oxygen levels might help identify the specific conditions associated with shortness of breath.

i feel the same way. My doctor said it was allergies.  I sometimes have allergies in the spring and fall but this is a definate starvation for air. I yawn also because I feel that is the only way to get a deep breat. I am getting a chest xray and blood work done but in the meqntime is there anything i can take to make me breath better.
