Key result
Mitral valve disease in dogs is linked to altered cardiac rhythms driven by neurohormonal remodeling.
Why the study?
Mitral valve disease is common in dogs and often associated with arrhythmias, but the relationship between the disease and cardiac rhythms requires further observation.
Observational
In dogs with mitral valve disease, arrhythmias are linked to neurohormonal compensatory mechanisms and cardiac remodeling.

Association of mitral valve disease with arrhythmia in dogs may warrant evaluation; leaves open prospective confirmation before changing practice.
The mitral valve disease is considered more common heart disease between dogs, and affected in the most geriatric and small size dogs. The most affected breeds are, Poodle, Pinscher, Yorkshire Terrier, Fox Terrier, among others. The general signs related to heart disease are cough, tachypnea and lethargic. Another common disorder is arrhythmia, basically related to origin or conduction alterations of electric impulses. Both disorders can be associated in the same patient, which makes necessary the realization of complementary tests for earlier diagnosis and placement of appropriate therapy for the dog, such as, chest radiography, electrocardiogram and echocardiogram. The aim of this paper was to observe, by means of cases retrospective study, the relationship between mitral valve disease and different cardiac rhythms. It was possible observe that alterations in cardiac rhythms are closely linked with activating of neurohormonal compensatory mechanism of organism due to cardiac remodeling caused for mitral valve disease.

Rosa et al. (2019) conducted an observational in Mitral valve disease and arrhythmia in dogs. Mitral valve disease was evaluated on Relationship between mitral valve disease and different cardiac rhythms. Mitral valve disease in dogs is closely linked to alterations in cardiac rhythms due to the activation of neurohormonal compensatory mechanisms from cardiac remodeling.
