What term describes a slow heart rate?

• A. Artery
• B. Bradycardia
• C. Cardiomegaly
• D. Distal

Answer: (B)

Bradycardia means a slow heart rate. It describes the heart beating at a rate that’s below what’s normal for the animal’s species at rest. That timing of beats matters for perfusion and can point to underlying issues like high vagal tone, hypoxia, electrolyte problems, thyroid insufficiency, or certain medications. The other options refer to different things: an artery is a blood vessel, cardiomegaly means an enlarged heart, and distal means located away from the center of the body. So the term that captures a slow heart rate is bradycardia.
