n. electrical impulses begin here
o. electrical impulses slow here to allow blood to move from the atria to the ventricles
p. a blood clot floating through blood vessels until it reaches a narrow area and blocks blood flow
match each of the medical conditions in the left column to the appropriate description in the right column.

1. acute myocardial infarction
2. cardiac arrest
3. angina pectoris
4. cardiogenic shock
5. congestive heart failure
6. hypertensive emergency
7. dissecting aneurysm

a. a condition where the heart cannot effectively pump blood, leading to fluid backing up into the lungs and edema
b. the sudden tearing and separation of the inner layers of the aorta, with the potential for great blood loss
c. the heart lacks power to effectively pump blood to the body, resulting in low blood pressure
d. systolic blood pressure greater than 180 mm hg
e. a lack of cardiac pumping activity
f. exertional chest pain, relieved by nitroglycerin
g. the complete blockage of a coronary artery

Explanation:

1. Atria are the upper chambers of the heart (L).
2. Coronary arteries are blood vessels that supply blood to the myocardium (C).
3. Atrioventricular node is where electrical impulses slow to allow blood to move from the atria to the ventricles (O).
4. Myocardium is heart muscle (G).
5. Sinus node is where electrical impulses begin (N).
6. Venae cavae carry oxygen - poor blood back to the heart (K).
7. Ventricles are the lower chambers of the heart (H).
8. Aorta is the body's main artery (M).
9. Atherosclerosis is calcium and cholesterol buildup inside blood vessels (B).
10. Dysrhythmia is an abnormal heart rhythm (D).
11. Ischemia is decreased blood flow and poor oxygenation (F).
12. Infarction is the death of tissue (I).
13. Tachycardia is a rapid heart rhythm, greater than 100 beats/min (J).
14. Asystole is an absence of heart electrical activity (A).
15. Bradycardia is an unusually slow heart rhythm, less than 60 beats/min (E).
16. Thromboembolism is a blood clot floating through blood vessels until it reaches a narrow area and blocks blood flow (P).
17. Acute myocardial infarction is the complete blockage of a coronary artery (G).
18. Cardiac arrest is a lack of cardiac pumping activity (E).
19. Angina pectoris is exertional chest pain, relieved by nitroglycerin (F).
20. Cardiogenic shock is the heart lacks power to effectively pump blood to the body, resulting in low blood pressure (C).
21. Congestive heart failure is a condition where the heart cannot effectively pump blood, leading to fluid backing up into the lungs and edema (A).
22. Hypertensive emergency is systolic blood pressure greater than 180 mm Hg (D).
23. Dissecting aneurysm is the sudden tearing and separation of the inner layers of the aorta, with the potential for great blood loss (B).
