Question

choose the correct answer. which term means \enlargement of the heart\? bradycardia cardiomyopathy cardiomegaly myocardial infarction

Explanation:

• bradycardia: Means a slow heart rate (brady - slow, cardia - heart), not enlargement.
• cardiomyopathy: Refers to a disease of the heart muscle, not specifically enlargement.
• cardiomegaly: The prefix "cardio-" relates to the heart, and "megaly" means enlargement. So this term means enlargement of the heart.
• myocardial infarction: Is the medical term for a heart attack, caused by blocked blood flow to the heart muscle, not related to heart enlargement.

Answer:

C. cardiomegaly (assuming the options are labeled A: bradycardia, B: cardiomyopathy, C: cardiomegaly, D: myocardial infarction. If the original labels are different, adjust the identifier but the text remains "cardiomegaly".)
