Write the definition of the following medical terms:

1. Atrioventricular defect
→ A congenital heart defect involving an abnormal opening between the atria and ventricles, often due to a malformed or absent atrioventricular valve (e.g., atrioventricular septal defect).

2. Bacterial endocarditis
→ An infection of the inner lining of the heart chambers and valves (endocardium), typically caused by bacteria entering the bloodstream and adhering to damaged heart tissue.

3. Myocarditis
→ Inflammation of the myocardium (the muscular layer of the heart wall), often caused by viral infections, autoimmune conditions, or toxins.

4. Pericarditis
→ Inflammation of the pericardium (the sac surrounding the heart), which can cause chest pain and may be due to infection, autoimmune disease, or other causes.

5. Angiocardiitis
→ Inflammation of the blood vessels and heart, particularly involving the coronary arteries and cardiac tissue; it may result from systemic inflammatory diseases like vasculitis.

6. Angiostenosis
→ Narrowing or constriction of a blood vessel, often due to plaque buildup or scarring, reducing blood flow.

7. Aortic stenosis
→ A narrowing of the aortic valve, which restricts blood flow from the left ventricle to the aorta, often due to calcification or congenital defects.

8. Arteriosclerosis
→ Hardening and thickening of the arterial walls, leading to reduced elasticity and increased risk of cardiovascular events.

9. Atherosclerosis
→ A specific type of arteriosclerosis characterized by the buildup of fatty plaques (atheromas) in the arterial walls, leading to narrowing and potential blockage.

10. Tachycardia
→ An abnormally fast heart rate, typically defined as more than 100 beats per minute at rest, which can be due to stress, fever, or heart conditions.

11. Hypertension
→ Chronically elevated blood pressure, usually defined as systolic ≥130 mmHg or diastolic ≥80 mmHg, increasing the risk of heart disease and stroke.

12. Hypotension
→ Abnormally low blood pressure, which can lead to dizziness, fainting, or inadequate blood flow to organs.

13. Hematoses
→ This term is not standard in medical English. It may be a typo or confusion with “hematosis.” If intended as “hematosis,” it could refer to a condition involving blood (e.g., accumulation of blood). However, this term is rare and not widely recognized. Possibly meant to be "hematoma" (a localized collection of blood outside vessels) or "hematopoiesis" (blood cell formation). Clarification needed.

*(Note: Likely a misspelling or error — common correct terms: hematoma, hemostasis, hematopoiesis.)*

14. Bradycardia
→ An abnormally slow heart rate, typically less than 60 beats per minute in adults, which may be normal in athletes but can indicate heart problems.

15. Cardiomegaly
→ Enlargement of the heart, often detected on imaging such as X-ray or echocardiogram, and may result from hypertension, heart valve disease, or cardiomyopathy.

✔ Summary:

- Most terms relate to cardiac structure, function, or vascular health.
- Common prefixes/suffixes include:
- *-itis* = inflammation
- *-osis* = condition/disease
- *-steno* = narrowing
- *-cardia* = heart
- *-megaly* = enlargement
- *-emia* = blood condition (though not present here)

> ⚠️ Note: "Hematosis" appears to be a rare or incorrect term. It might be a typo for hematoma, hemostasis, or hematopoiesis. Please verify the intended word.
