Trying to use youtube videos to understand my abnormal exercise EKG.  At rest the pattern is just fine with

a normal "p" wave followed by a normal "qrs" and normal "t" wave.  The interval measurements appear normal.  Then after

5 minutes into exercise, the "p" wave is quite distorted possibly becomes 2 "p" waves and then that whole atrial section becomes

like scribbles with no obvious pattern and no repetition. The "qrs" appears still in tact.  During recovery things become fairly

normal after 3 minutes with a couple of weird segments thrown in.  The best I can discern is that this indicates Atrial fibrillation.  This

is possibly associated with heart failure as best I can understand it.  The HF stood out to me as I also have high NT-ProBNP, also an

indicator of future heart failure.   My cardiologist appears to be of the mind that one shouldn't bother their little heads with things they

can't do anything about, so I guess that's why he didn't go over this with me.  So I'm wondering:

 1. does my analysis seem reasonable?  

 2. Is afib an indicator of Heart failure? If I have no symptoms, is it of concern? 

3. Is there anything one can do about afib?   

Angina was also mentioned with afib (my mother had angina at about my age).  I have no symptoms

and had no symptoms on the treadmill.

Any comments are welcome.  Thanks, Laura
