unfortunately, this is not enough information for me to describe what is going on with your heart. From the results you gave me, it sounds like you have a good working hard. Anyways, if they recommended you to see a cardiologist for a heart block I would highly recommend doing that because occasionally these can worsen. In the meantime you should take aspirin, try to exercise, eat healthy, avoid fast food, avoid tobacco, avoid alcohol, avoid fatty foods, avoid foods that are high in cholesterol, and try to eat more mega threes. You should try to also control all your other medical problems if you have any.
