Irregular Heart Rhythm in Dogs is also known as Sinus Bradycardia (SB), which indicates a slower-than-normal rate of impulses in the sinus node. It initiates the electrical pulses with the heart that helps it in triggering the heart to contract or beat. Mostly, slow sinus electrical impulses are benign that can be beneficial. Still, it can also cause loss of consciousness, if it brought about an underlying disease that disrupts the cardiac nerves. It acts as the heart’s control system. It is a fairly common disease in dogs in a variety of breeds. However, this irregular heart rhythm is more common in young dogs than older ones. Todays’ article on pets trouble with letting you know about the Irregular Heart Rhythm in Dogs along with its symptoms and treatment.
Irregular Heart Rhythm in Dogs – Symptoms and Treatment
Symptoms and Type
Well the thing about to worry is that the dog might not show any signs of these diseases, if it is very active or engage in athletic training. Typically, the SB can be observed when the dog is in the state of rest. Some symptoms associated with the SB includes;
- Loss of consciousness
- Excessively slow breathing, especially under anesthesia
- Underlying disease
The veterinarian will accomplish a complete physical exam, with thoroughly checking its background history of symptoms. The dog’s overall condition and the possible incident may be the cause of these diseases.
The veterinarian will perform all kinds of blood profiles that will include chemical blood profile, complete blood count and urinalysis. It results in the indication of presences of substances that may cause the slowed heart rate. These tests will also highlight the deficiencies in the blood that may give a clue of kidney failure. The doctor can also prefer X-ray and ultrasound to have a visual examination of internal organs to check any abnormalities in the heart and other internal organs. An ECG recording can also be used to examine the electrical currents in the heart muscles that may reveal any Irregular Heart Rhythm.
Treatment will be determined by using the underlying disease. Mostly, dogs do not show any kind of clinical signs and require no treatment. Those dogs which do not have any structural heart diseases or heart rates provide an average cardiac output at rest. Therapeutic approaches vary markedly that depends on what’s causing the SB, the ventricular frequency and severity of clinical signs.
If the dog is in critical condition that may be treated as an inpatient while the intravenous fluid therapy can be administered and the dog’s health stabilized, restriction on activity will not be recommended unless the dog has symptomatic SB that is related to structural heart diseases, then exercise constraint will be supported until medical and surgical intervention can stabilize the problem.
The veterinarian may order for further monitoring depending on his final diagnosis. If signs are present that they should be resolve with correction for the underlying causative conditions. However, for a longer run the dog will be rechecked if structural heart disease found.
