Question

Quizplus · Accepted Answer

Tachycardia refers to a fast heart rate, while bradycardia refers to a slow heart rate. Therefore, option C is the correct pair of terms that are opposite in meaning. Option A (tachycardia; bradycardia) also has opposite meanings, but the terms are in the wrong order. Option B (bradycardia; cardiomyopathy) pairs a term that refers to heart rate with a term that refers to heart muscle disease, which are not opposite in meaning. Option D (cardiac tamponade; bradycardia) pairs a term that refers to the accumulation of fluid around the heart with a term that refers to slow heart rate, which are not opposite in meaning. Option E (none of the above) is incorrect because option C is the correct choice.
