Intermittent heart block

I have just been put on a monitor for 7 days having been diagnosed with Intermittent heart block, naturally this has made me more sensitive to being breathless or dizzy.  However, there is also the issue of the "red car syndrome".  You know how it is; you buy a red car and every car you see on the road seems to be red.  So I am more aware of any variations in how I feel at any moment in time.  
Sometimes I sense mini-episodes of slight light headedness, other times they are higher in amplitude and longer in duration.   However, I only seem to get any events when I sitting/ standing still not when I am moving around doing daily chores.  So my question is this:  Are the signals from the sinus region to the ventricals stronger when one is more physically active or are they the same amplitude all the time.

What degree of heart block do you have?

Thanks for replying bbxx.
I had the heart monitor on for six days and in that time I logged 44 incidents of "light headedness".  However, these were interdespersed with several incidents of very subtle sensations--they almost felt like the movement of air caused by a peice of paper moved near my face.  Since I have returned the monitor for analysis I have had very few incidents of anything.  I go to see my GP doctor on the 10th June when the results will be discussed with me.  
I will let you know the results then, I will check the forum before then to see if there are more posts.  bye for now
