What are the types of heart disease in rabbits
1. Congestive heart failure
Congestive heart failure in rabbits is difficult to detect, and it is usually easier to detect when the rabbit is severely ill. Symptoms of congestive heart failure in rabbits include hindlimb weakness in the initial stage of the disease, progressive generalized weakness and exercise intolerance as the disease progresses, decreased appetite, weight loss, dyspnea, and blockage of specific organ functions such as polyuria, renal damage, etc.
Heart failure symptoms in rabbits are different from heart failure symptoms in other animals. Cough symptoms are not common in sick rabbits.
2. Congenital heart disease
Rabbit congenital heart defects are relatively rare, and the clinical symptoms of the disease are mainly manifested as interventricular septum Defects, pulmonary hypertension and large vessel defects.
3. Arrhythmia
Arrhythmia problems rarely occur in animals such as rabbits, cats and dogs Although there are still a few cases in the body, rabbits with arrhythmia generally show syncope symptoms. How to find the clinical symptoms of arrhythmia in sick rabbits requires timely diagnosis and treatment, and the cause of arrhythmia in rabbits should be investigated first. The antiarrhythmic drugs currently used by some people can also be used for sick rabbits.
4. Cardiac disease
Myocardial disease is the first common disease in elderly rabbits, especially large rabbit breeds are more likely to suffer from this disease. sick. There are three types of myocardial disease in rabbits: dilated, hypertrophic, or restrictive.
Rabbit stress cardiomyopathy and sudden death in rabbits are mostly related to excessive stress, which is caused by the release of large amounts of catecholamines.
Dilated cardiomyopathy in rabbits is the most common type of myocardial disease in rabbits, but diseased rabbits generally do not show clinical symptoms until their myocardial function is not severely impaired.
5. Valve disease
Actually, it is related to the mitral and/or tricuspid heart valves Endocardial diseases of the rabbits are rare in the animal population, but these diseases can affect older rabbits more. The most common clinical manifestation of valvular disease in rabbits is a systolic parasternal murmur. The diagnosis of the disease can be carried out by echocardiography, which is determined by the basis of diseases such as valve thickening and ventricular dilatation.
6. Vascular disease
The incidence of spontaneous arteriosclerosis in New Zealand white rabbits is relatively high, and the incidence rate can reach 40%. The main clinical signs of vascular disease in rabbits are usually nonspecific and include symptoms such as lethargy, anorexia, and weight loss. Vascular disease in rabbits is difficult to diagnose, and only in some cases vascular calcification can be seen on radiographs. The etiology of spontaneous arteriosclerosis in rabbits has not yet been identified, but it is suspected that there are more genetic factors than rabbits.
