The endocardium, from endo-, meaning inner or within, and cardi(o)-, meaning heart, is the thin inner layer that lines each chamber. The myocardium, from myo-, meaning muscle, and cardi(o)-, meaning heart, is the middle, muscular layer that contracts to pump blood. The epicardium, from epi-, meaning upon or on, and cardi(o)-, meaning heart, is the outer layer.

Explain the following tests/diagnostic procedures:
a.) Sphymomanometer
b.) Stethoscope
c.) Holter monitor
d.) Echocardiogram
e.) EKG
f.) Stress test
g.) Ultrasonography
h.) Cardiac enzymes
a.) instrument to measure pressure. Most nonmedical people call it a blood pressure cuff
b.) instrument for viewing. This tool, as you know, is used to listen for the sounds of the heart, but it also helps us listen to other body sounds like the lungs and intestines
c.) a portable ECG machine that the patient wears over a few days. The monitor records heart activity to show a possible pattern for the symptoms the patient may be having
d.) a test that uses ultrasound to look at the heart and its vessels
e.) The machine records the electrical activity of the heart. This test helps check heart rhythm and may diagnose other heart issues
f.) evaluate how well the system is working. The patient’s oxygen levels and EKG are monitored during the test.
g.) This test uses ultrasound to look at blood going through blood vessels to determine if they are narrowed or have a thrombus
h.) used to measure certain items in the blood that may indicate heart muscle damage.

Explain the follow treatments:
a.) Heart transplant
b.) CPR
c.) Cardiac catheterization
d.) Pacemaker
e.) Implanted defibrillator
a.) a surgical procedure in which the patient’s heart is replaced with the heart from a donor. This procedure allows patients to live when all other options won’t work.
b.) Cardiopulmonary Resuscitation
c.) insertion of a catheter into a chamber or vessel of the heart
d.) a small electronic device implanted in the chest signals the heart to beat when the heartbeat is too slow or irregular
e.) shocking the heart to restore normal rhythm
