Why does the heart has different types of tissues?

The heart does consist or atria, ventricles, etc. but these are the gross, anatomical divisions of the heart. In asking about the kinds of tissues contained in the heart, we have to think of the cells found there. The heart obviously contains cardiac muscle, it is practically the only site where it is found, except for the transitions between the heart and the large vessels arising from it. Cardiac muscle consist of the typical cardiac muscle cells, which are di-nucleated, branched cells which connect to each other at intercalated disks, making the heart muscle a functional syncitium. In addition, the heart contains modified cardiac muscle cells called Purkinje cells. These cells transmit electrical impulses to the ventricles, to stimulate them to contract. The heart also contains connective tissue, serving various purposes, such as binding groups of cardiac muscle cells into fascicles, etc.
