I finally heard from the Doctor about the results of wearing a heart monitor for a month.  The nurse from the Family Clinic called and read me the report.  It said that I had some tachycardia (heart too fast) and some bradycardia (heart too slow) but these arrhythmias were not very significant and were not the cause of my dizziness.   So, that’s that.  I was hoping for a definitive answer, and I believe I got one.  My light headedness and other symptoms are not related to my heart.  That’s a good thing.  I would still like to find out what is the causing me to feel bad, so I will make an appointment with the Doctor and see what he can do.
