What is canine syncope?

Fainting is the medical term for dizziness. When a dog's brain temporarily loses consciousness due to insufficient blood and oxygen supply, it is called canine syncope.

Causes of syncope in dogs

1. Cardiovascular system: Fainting in dogs may be related to problems with the heart or other organs of the body. Fainting related to exercise may be related to underlying related to heart problems. Heart problems include: abnormally low or high heart rate, damage to the heart muscle or valves, heartworms, and heart tumors. Diseases caused by the heart can prevent sufficient blood oxygen from reaching the brain, causing fainting.
2. Vascular and vagal syncope: Sudden stimulation or pressure causes a brief drop in blood pressure and stimulates the vagus nerve, leading to fainting.
3. Postural fainting: Dogs may faint due to coughing, defecation, urination or swallowing.
4. Other causes: hypoglycemia (hypoglycemia) and drugs (special drugs that affect blood pressure), etc.

Clinical symptoms of syncope in dogs

Canine syncope is a clinical symptom of an underlying disease. The dog may first appear weak, then collapse or collapse suddenly. It will lose consciousness for a few seconds, and then fall again. Regain consciousness.

How to diagnose syncope in dogs

1. First, the doctor must identify whether the dog is really syncope. Because some neurological disorders (such as epilepsy) may look similar to fainting, once fainting is confirmed, the physician must determine the underlying cause. This can be done through a clinical history and special laboratory tests, including blood tests, Cardiopulmonary auscultation and pulse palpation.
2. In addition, the heartworm test is a must-have item. In addition, electrocardiograms, cardiac ultrasound tests, and chest x-rays can be used to evaluate heart function. If a dog is suspected of having neurological abnormalities, cerebrospinal fluid sampling and brain wave testing can be performed to evaluate the brain and its activity.

Treatment of syncope in dogs

Treatment of syncope in dogs depends on the underlying cause. Treatment includes: reducing the likelihood of dizziness, minimizing movement or stimulation, and using stool softeners to reduce irritation during bowel movements.
In addition, special pharmacotherapy may be used to improve cardiac function and minimize vasovagal syncope, and any medications that may cause syncope should be discontinued or avoided.
