This video describes a protocol to perform echocardiography on a laboratory mouse.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Echocardiography Determine the body weight of the mouse using a standard laboratory balance while holding it lightly by the tail to ensure proper positioning. Anesthetize the animal by the intraperitoneal (i.p.) injection of 50 mg/kg pentobarbital. NOTE: Any other kind of anesthesia can…
