| The contraction and relaxation of cardiac muscle results from the depolarisation and repolarisation of myocardial cells. |
| The latter is known to be due to the fact that hypocalcemia prolongs the duration of phase two of the action potential of cardiac muscle. |
| It has therapeutic use in congestive heart failure and edema, having a positive inotropic effect on cardiac muscle. |
| The importance of free fatty acids in aerobic metabolism is best shown in cardiac muscle. |
| The transverse tubular system of cardiac muscle is a structure that allows rapid propagation of excitation into the cell interior. |
| Histology, immunohistochemistry, and ultrastructure were highly suggestive of transdifferentiation from cardiac muscle to adipose tissue. |
