Cardiac Arrest in Dogs
Cardiopulmonary Arrest in Dogs
Cardiac arrest (also known as cardiopulmonary arrest or circulatory arrest) occurs when normal blood circulation ceases due to the heart's inability to contract (heart failure). Like many other body systems, the respiratory and cardiovascular systems work in a coordinated fashion. Therefore, if a dog fails to breathe for more than six minutes, it can lead to heart failure and cardiac arrest -- both of which can be fatal. Cardiac arrest can occur in dogs of any age, sex, or breed.
Symptoms and Types
Blood circulation may remain intact if the animal resumes breathing within four minutes of the initial problem. However, if it lasts longer than six minutes it can lead to cardiac arrest. Common symptoms associated with this emergency include:
Cardiac arrest is an emergency that will require immediate veterinary assistance to assess the animal's condition and the form of treatment. You will need to give a thorough history of your dog’s health to your veterinarian, including the onset and nature of the symptoms and possible incidents that might have precipitated the complications. He or she will then perform a complete physical examination, focusing on the dog's airways, breathing ability, and circulation. Your veterinarian will also constantly monitor your dog's blood pressure and pulse rate.
Routine diagnostic exams used to determine the underlying cause of the cardiac arrest include chest X-rays, complete blood count, biochemistry profile, and urinalysis. Blood samples are collected to determine the level of gases, including oxygen, in the blood. Dogs suspected of having an underlying heart disease may undergo echocardiography to evaluate the extent of the problem.
