Meaning of results

I am a 62 year old male who was diagnosed with coronary heart disease last August at which time two stents were put into my heart. The disease was discovered during a routine annual checkup treadmill which revealed an arrhythmia. After having the stents implanted, the arrhythmia returned. I am now taking Cartia (100mg), Plavix (75mg), and Lipitor (10mg) once a day, and Verapamil (40mg twice a day).

In January, my cardiologist did a 24 hour halter test. I've just received the report. Here is a summary of the results:

My problem is  that I don't understand what this all means and my GP simply tells me not to worry. I should add I live in Hong Kong and that my GP and cardiologist are both Chinese. It has been my experience that in their culture there is far less communication between patients and doctors that in the U.S. and even in the U.S. I was viewed as a bit of a pain because I ask a lot of questions.

What does this mean?  How good or bad are these results?  What should I do, if anything, to help myself get better?
