Hello. Yes, it is possible as the heart tries to compensate for the low BP. You can also have this situation with a condition called hypovolemia, where there is excessive loss of blood due to disease or trauma. Some drugs can do this too. Thanks for using Petco Pet Education Center, formerly Petcoach.
