Proper electrocardiography (ECG) starts with proper positioning. For a diagnostic ECG, the patient must be restrained in right lateral recumbency with the legs perpendicular to the body and parallel to each other.
Congenital cardiac defects are those present at birth, and are most often from a genetic cause. In addition to genetic causes, they can also be from infectious, environmental, pharmaceutical, or a variety of causes.
Veterinary technicians are the veterinary hospital's mainstay when it comes to carefully and successfully anesthetizing critical patients. A large number of elderly canine and feline patients are affected by cardiac disease, and knowledge of how to safely monitor, anesthetize, and problem solve cardiac patients makes for a less stressful anesthesia for both the patient and technician.
