Final answer:

Tachycardia, bradycardia, and fibrillation are abnormal heart rates that have distinct characteristics and potential symptoms.


Explanation:

Tachycardia: Tachycardia is a condition where the resting heart rate is too fast, exceeding 100 beats per minute. It can lead to symptoms such as dizziness, shortness of breath, and chest pain.

Bradycardia: Bradycardia is the opposite of tachycardia, characterized by a resting heart rate below 60 beats per minute. Symptoms may include weakness, fainting, and chest discomfort.

Fibrillation: Fibrillation refers to the rapid, irregular, and unsynchronized contraction of the heart muscle fibers. It can lead to serious conditions like ventricular fibrillation, requiring immediate medical attention.
