Should I tell all?

Back on Feb. 1 I had a 72hr cardiac holter monitor test, & also an echocardiogram.

My Family Doctor told me both tests yielded a normal result, which of course I was happy to hear. I have a telephone consultation with the Cardiologist come March 23. It's my plan to let him know that those tests must have caught me on good days, because my pulse is very commonly below 60, sometimes as low as 52. I also am a little lightheaded when first getting out of bed, & during the day. I have an oximeter, & very frequently my pulse is below 60. Last year, after a cardiac holter monitor test my pulse was at 52, & the Cardiologist didn't like it, resulting in my medication being reduced to boost the pulse rate. There are may days where I feel like cr*ap, & I'm sure it's because of low pulse rate. Should I tell all when speaking with the Cardiologist.? I currently am taking 5mg Bisoprolol, but it has been cut down to 1/4 tab..which has not boosted the heart rate. 

Thanks in advance for your help.
