Cardiac muscle tissue is an extremely specialized tissue which is only found in the heart and it has the following special features:

i) It has similar characteristics of skeletal as well as smooth muscles. Like skeletal muscle tissue it is striated and like smooth muscle tissues it has cells connected together by intercalated discs.

ii) It can sustain contraction and relaxation rapidly and in complete efficient coordination and synchronization.

iii) The cardiac muscle tissue is involuntary and unlike other muscle tissues it doesn’t get tired.
