Cause: can occur as electrophysiological complication of other "malignant" (ie prefibrillatory) ventricular arrhythmia such as very fast and sustained ventricular tachycardia (VT) in the presence of severe organic myocardial disease (eg sub-aortic stenosis or "Boxer dog cardiomyopathy"). Clinical ventricular arrhythmias in afflicted dogs are influenced by perturbations in the autonomic nervous system . Because stimulation of α- and α-adrenergic receptor types has complex and different effects on electrophysiological properties of Purkinje fibers and ventricular myocardium in afflicted dogs, a net effect of increased sympathetic tone is difficult to predict. Arrhythmia in dogs may be caused by a number of conditions, though sometimes these are fairly harmless and just require monitoring, diet management, and staying in shape.Irregular heart beats can The ventricular premature contractions (VPCs) typically have a large T wave in the opposite direction of the QRS complex, no ST shelf, and no discrete relationship to P waves.

For sustained VT, use lidocaine (2-4mg/kg bolus--over a minute) and Canine Cardiac Arrhythmia – Understanding Heart Problems in Dogs. Arrhythmia is the term used to describe heartbeats that are either too fast or slow. Abnormal Either supraventricular or ventricular arrhythmias were observed, despite group B dogs showed higher occurrence of supraventricular arrhytmias.

Ventricular Tachycardia can be diagnosed by an electrocardiogram (ECG). Treatment The results reported here show that heterogeneous sympathetic innervation occurs in a colony of German shepherd dogs with inherited ventricular arrhythmia and sudden cardiac death. This naturally occurring model of sudden cardiac death provides unique opportunities to test long-standing hypotheses that relate sympathetic imbalance to arrhythmogenesis.

Moreover, the window of vulnerability to ventricular arrhythmias and the age and circumsta … The clinical ventricular arrhythmia in these dogs is influenced by perturbations in the autonomic nervous system . The circumstances of death during sleep suggest this effect and the identification of the greatest frequency of VT during rapid eye movement sleep (REM) further supports this conclusion . During sleep elevated parasympathetic tone is peppered with bursts of sympathetic tone, and such a combination could be the trigger for the ventricular arrhythmias in these dogs. Spontaneous ventricular arrhythmia (VA) and sudden death occur in young German Shepherd Dogs (GSDs).
Secondary myocardial disease can result from viral, bacterial, mycotic, and protozoal infections, hyperthyroidism, hypothyroidism, anemia,
Diagnosing Cardiac Arrhythmia in Dogs Your vet will need a complete medical history and a thorough physical exam in order to diagnose the cause of your dog's cardiac arrhythmia. Blood tests, urinalysis and other lab work should be performed; a number of illnesses, such as hypothyroidism, can cause canine cardiac arrhythmia. Se hela listan på merckvetmanual.com
When amitriptyline was infused into dogs ventilated with various respiratory rates, ventricular arrhythmia resulted in 18 of 18 (100%) dogs with pH less than 7.42, 2 of 4 (50%) dogs with pH between 7.48 and 7.51 and 0 of 8 (0%) dogs with a pH between 7.59 and 7.65 (P less than or equal to .001). In many dogs, VPCs are due to underlying heart disease so an echocardiogram is recommended when a diagnosis of ventricular arrhythmia is made. Other causes of VPCs in dogs include electrolyte or metabolic derangements (which are diagnosed via blood work), intra-abdominal disease (usually diagnosed via abdominal x-rays and/or abdominal ultrasound) and severe systemic diseases.
