Researchers have found a reliable way to measure the pulse rate of reptiles at a convenient location on the back of their heads, where this pulse rate aligns with the heart rate in healthy reptiles.
At Cornell University, researchers have identified a spot on the back of reptiles’ heads that makes it easy to consistently gauge their pulse rate, which corresponds to their heart rate if they are healthy. This technique involves using an ultrasonic Doppler flow detector, a common tool found in many veterinary practices.
Though the area for measuring a python’s heart rate is already established, an accurate spot for checking pulse rate had not been clearly defined until now, noted Nicola Di Girolamo, an associate professor specializing in exotic animal medicine. The capacity to assess pulse rate leads to a more thorough cardiovascular evaluation.
The study began with a bearded dragon that was experiencing health issues due to an aneurysm, which resulted in the enlargement of the temporoorbital artery located at the back of its head.
“When you place the Doppler in that area, the pulse rate is clearly audible,” Di Girolamo, who is the study’s corresponding author, explained. “Initially, we thought this effect was unique to the swollen vessel, but after randomly checking another bearded dragon in the same area, we discovered it had a detectable pulse there too.”
The team identified the same pulse point in other reptile species, including leopard geckos, turtles, tortoises, and snakes.
Di Girolamo mentioned that an increasing number of reptile owners are now open to pursuing advanced medical treatments for their pets, such as surgery. This method offers an additional way to monitor a reptile’s heartbeat while they are under anesthesia or when treating an animal that may be agitated. “Using this approach can be simpler and less stressful,” he remarked.
