With some patient's, this medication is used to help maintain a normal heart rhythm. This medication should not be administered to patients with such as uncontrolled congestive heart failure, shock from severe heart problems or slow heartbeat. The diaphragm provides which of the following functions for the heart? -Divides the chest and the abdomen -The bottom portion of the heart is anchored to the diaphragm -The top portion of the heart is anchored to the diaphragm -All of the above - correct answers The bottom portion of the heart is anchored to the diaphragm The heart is located behind the sternum and above the diaphragm.

Myocardial ischemia is damage of a patients heart tissue that is caused by not getting sufficient blood flow to that part of the heart. Occluded artery is when plaque builds up in an artery and makes it more narrow.
