Atrial tachycardia - Dog. Atrial tachycardia is a common cardiac abnormality of dogs characterized by supraventricular impulses originating from outside the sinoatrial node.
This condition is thought to be due to an abnormal automatic focus within the atrium, often a result of atrial fibrosis due to underlying cardiac pathology that interrupts contiguity between the SA node and the surrounding atrial myocardium, or triggered by sympathovagal discharges from the autonomic nervous system. Causes include: With atrial tachycardia, cardiac compensation for this phenomenon occurs by re-entrant circuits which allow the impulse to re-stimulate the atrium and to pass down to the ventricle. Treatment and Symptoms of Dog Tachycardia. Boxer cardiomyopathy. Overview Boxer cardiomyopathy shares striking similarities to a human myocardial disease called arrhythmogenic right ventricular cardiomyopathy (ARVC). On histopathology, the disease is characterized by the progressive replacement of ventricular myocardium (primarily right ventricular myocardium) with fatty or fibro-fatty tissue. Clinically, the disease is characterized by the development of ventricular tachyarrhythmias, including ventricular tachycardia and ventricular fibrillation.
Affected dogs are at risk of syncope and sudden cardiac death. Cause Boxer cardiomyopathy is a genetic disease inherited in an autosomal dominant pattern. The presentation in affected offspring is quite variable, suggesting incomplete penetrance. In 2009, a group led by Dr. Clinical presentation How to Help a Dog With an Irregular Heartbeat. See your vet right away if you suspect your dog has an irregular heartbeat.
By: Ally Aubry An irregular heartbeat is one that is too fast, too slow or has an erratic pattern. Not all irregular heartbeats are serious — indeed, a slow heartbeat in an athletic dog could just be proof he is very fit! However, if you suspect your dog has an irregular heartbeat and especially if he shows symptoms, for peace of mind, get him checked by your veterinarian.

Diagnosis Clinical signs Systolic heart murmur over left base or apex, often exacerbated at exercise or by use of short acting agents that increase contractility or reduce afterload. Differential diagnosis. Heart: hypertrophic cardiomyopathy (HCM) Diagnosis of Cardiovascular Disease in Dogs: Heart and Blood Vessel Disorders of Dogs: The Merck Manual for Pet Health. A veterinarian often diagnoses cardiovascular disease by reviewing the medical history and signs, conducting a physical examination, and interpreting the results of specific tests or imaging procedures.
The physical examination includes using a stethoscope to listen to the sounds made by the dog's internal organs, especially the heart, lungs, and abdominal organs, and examining parts of the body by feeling with hands and fingers to distinguish between solid and fluid-filled swellings.

It is so hard to accept that veterinary medicine has no cures for illnesses like Congestive heart failure and that cherished time with the pet you love is now limited.
Prevent Your Pet from Developing Heart Disease. Signs of Heart Disease in Dogs. Canine Heart Disease - Cardiac Illness in Dogs. Overview/Description of DiseaseThe heart is a muscular pump which pushes blood around the entire body.
In a normal dog it beats approximately 150,000 times a day. A muscle that works this hard needs to be in shape (with good muscle tone) to do its job effectively! The heart is actually made up of two pumps because a dog's body, like ours, has two different circuits for blood flow, moving first through one and then the other. One of these circuits takes blood through the lungs so that oxygen can be replenished and waste gases, such as carbon dioxide, are removed. This oxygen-enriched blood then moves through the other circuit, reaching all parts of the body to deliver the oxygen needed for normal body function and removing waste products as needed.
Heart disease causes a disruption in circulation; blood is pumped less effectively, leading to poor blood supply to muscles and organs. Dogs are often at risk for certain types of heart disease depending on genetics, breed, age, and size. Diagnosing Canine and Feline Heart Disease. Diagnosing heart disease and/or heart failure in the dog and cat requires a combination of several different testing methods.
The Role of the Physical Examination in Diagnosing Heart Disease Accurately diagnosing any disease or condition always begins with a thorough physical examination. A complete physical examination may uncover a symptom that suggests the possibility that your dog or cat is suffering from heart disease, such as a heart murmur (also seen in cats), evidence of fluid in the lungs or in the abdomen, or other signs seen with heart problems. Your veterinarian will also ask about your pet's history. Specifically, you may asked whether your pet coughs, tires easily, sleeps more than normal, breathes heavily and similar types of questions.
