Which term is used to describe a rapid heartbeat in animals?

Tachycardia is the term used to describe a rapid heartbeat in animals. When an animal experiences tachycardia, its heart rate exceeds the normal range for its species, which can indicate various underlying health issues including stress, pain, anxiety, or cardiovascular problems. Understanding the normal heart rates for different animals is essential for identifying when tachycardia occurs.

The other terms do not relate to heartbeat. Anisocoria refers to unequal pupil sizes, which can be indicative of neurological issues. Jaundice is characterized by a yellow discoloration of the skin and mucous membranes due to elevated bilirubin levels, often indicating liver or hematologic problems. Gingiva pertains to the gums, which are the soft tissues surrounding the teeth, and while they are important for oral health, they are not related to heart rate or cardiovascular conditions. Recognizing these terms helps differentiate between various medical conditions in veterinary medicine.
