The rate of intravenous Fosphenytoin sodium injection administration should not exceed 150 mg phenytoin sodium equivalents (PE) per minute because of the risk of severe hypotension and cardiac arrhythmias. Careful cardiac monitoring is needed during and after administering intravenous Fosphenytoin sodium injection.
Does scar tissue developed after heart attack can lead to heart failure? Yes: The area that is scarred does not work and help in the pumping and the heart gets weaker. The scarred tissue also impedes the contraction and makes the pumping even weaker, and it does not conduct electrical current like the normal muscles. The weaker heart, puts out less blood that goes in the heart, hence, the heart failure. ...Read more.
Cardiac muscle tissue affected by the heart attack dies. A heart attack is also called a myocardial infarction. Myocardium just means heart muscle, and infarction means tissâ¦ue death due to lack of oxygenated blood flow. Therefore, a heart attack is death of muscle tissue as a result of reduced blood flow to the heart. This is usually because the blood vessels that bring oxygen-rich blood to the heart (the coronary arteries) become blocked by a clot (also called a thrombus or embolism).
