Explanation
Sinus bradycardia is the correct answer because it is a type of abnormal heart rhythm characterized by a slower than normal heart rate. In sinus bradycardia, the sinus node, which is responsible for generating the electrical signals that control the heart rate, fires at a slower rate than usual. This can cause symptoms such as fatigue, dizziness, and fainting. Sinus bradycardia can be caused by various factors, including certain medications, underlying heart conditions, and an imbalance in the autonomic nervous system. It is important to diagnose and treat sinus bradycardia to prevent complications and improve heart function.

C. Normal Sinus rhythm
Explanation
The correct answer is "Normal Sinus rhythm." This is because sinus rhythm refers to the normal electrical activity of the heart, where the electrical signals originate from the sinus node and follow a regular pattern. In normal sinus rhythm, the heart rate is within the normal range of 60-100 beats per minute. Sinus tachycardia refers to a faster heart rate, while sinus bradycardia refers to a slower heart rate. Since the question does not mention any abnormalities in heart rate, the correct answer is normal sinus rhythm.
