Answer:
The answer to the question: Tachycardia refers to a heart rate of more than 100 beats per minute, would be, A: True.
Step-by-step explanation:
When the body is at rest, usually, the heart should be beating between 60 to 70 beats per minute. Variations in these numbers will depend on the activity the person is doing, and other circumstances that may affect it. However, the heart has its own regulatory system, and its beats should never, under normal circumstances, reach over a 100 bpm. If this happens, if the heart, for no reason (excesive exercise, use of certain medication to produce tachycardia, drugs) starts going up the speed measurement to over 100, it is really dangerous, and the condition is known as tachycardia. This is why the answer is true.
