the hollow muscular organ lying on the sternum that serves as a pump controlling the blood flow in two circuits, the pulmonary and the systemic. See also circulatory
a mechanical device that replaces the heart by using pulsating air to pump blood to the body. Successfully placed in calves, sheep and dogs as experimental models for the subsequent use of such methods in humans.
ossicles in the fibrous skeletal ring which surrounds the aortic orifice of the heart in cattle and occasionally in other species; called also ossa cordis.
heart conducting system
consists of the sinoatrial node, the atrioventricular node, the atrioventricular bundle and its two crura.
cyanotic heart malformations
insufficient oxygenated hemoglobin is received in the peripheral capillary beds resulting in blue discoloration of tissues, and an incapacity of the body to maintain a life-sustaining level of activity.
an all-embracing term including those diseases in which there is intrinsic disease of the heart such as uremia, valvular disease, African horse sickness, vitamin E-selenium nutritional deficiency, inherited cardiomyopathies of dogs and cattle, altitude sickness, canine parvovirus infection, and in a number of plant and other poisonings. See also mulberry heart disease
heart failure cells
hemosiderin-laden macrophages present in the pulmonary alveoli in cases of congestive heart failure.
includes ectopia cordis, patent foramen ovale, ventricular septal defects such as Fallot's tetralogy, Eisenmenger complex, patent ductus arteriosus, aortic coarctation, right aortic arch persistence, truncus arteriosus persistence, fibroelastosis, subvalvular aortic stenosis, anomalous origin of carotid arteries, transposition of great vessels, pulmonic stenosis, aortic stenosis.
heart meridian points
acupuncture points along the heart meridian.
the number of contractions of the cardiac ventricles per unit of time. For normal rates see pulse
a concept which sets out that performance in racing horses is related to heart size, now a well-established relationship, and that heart size can be estimated in the living horse by the measurement of the QRS interval.
is an unpopular concept in any medical science but overtrained horses which perform poorly do have a high incidence of abnormal T waves.
heart valve anomalies
failure of complete development of atrioventricular or semilunar valves results in stenosis or incompetence of the valves and often congestive heart failure.
heart valve hematoma
congenital, usually multiple lesions on the edges of atrioventricular valves, mostly in calves; disappear spontaneously in most cases.
heart valve thrombosis
common lesion on the free edges of valves, often the source of widespread emboli; on healing leave scarred, insufficient valves.
flaps of endothelial connective tissue that guard the entrance into and exit from the ventricles and bring about unidirectional blood flow. Include the atrioventricular and semilunar valves, the proper closure of which is essential to maintain circulatory equilibrium, can be diseased and cause heart failure. See also heart murmur
Patient discussion about heart disease
Q. heart disease? how to prevent from heart disease?
A. Eat well (less fat, more vegetables), exercise, don't smoke, don't drink too much, watch your body weight, and go for a check-uo from time to time.
These are good points to start with, and will keep you busy enough... You can read more here (http://www.nlm.nih.gov/medlineplus/heartdiseasesprevention.html)
Q. what do i need to do if i suffer from heart disorder? do i need to change my diet? what is a heart disorder?
A. There are many types of heart disorders, and you need to be aware of exactly what you have. A change in diet- to a low-fat low cholesterol diet, combined with regular physical activity, is best for heart problems that involve atherosclerosis (occluded blood vessels that cause damage to the heart and can cause a heart attack). You have to see a doctor or a cardiologist for proper diagnosis and treatment, including diet plans.
Q. What are the Risks for Developing a Heart Disease? What are the major factors that might increase my risk for developing a heart disease?
A. There are many risk factors that are known nowadays for developing a heart disease. Among the major risk factors are: Being a male, being over 50 years of age, smoking, consuming alcohol, doing no physical activity, being obese, having hypertension (chronic high blood pressure), being diabetic and having a family history of heart disease (in first degree relatives). Also a high cholesterol diet is known to increase chance of atherosclerosis, a process that happens in the blood vessels and can cause heart attack.More discussions about heart disease
