Rumination syndrome is a poorly understood disorder, and a number of theories have speculated the mechanisms that cause the regurgitation, [3] which is a unique symptom to this disorder. While no theory has gained a consensus, some are more notable and widely published than others.
Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve insufficiency causes regurgitation through that valve, called aortic regurgitation, and the terms aortic insufficiency and aortic regurgitation are so closely linked as ...
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown on an echocardiogram and ...
Medications that may cause or worsen the disease include benzodiazepines, calcium channel blockers, tricyclic antidepressants, NSAIDs, and certain asthma medicines. Acid reflux is due to poor closure of the lower esophageal sphincter , which is at the junction between the stomach and the esophagus.
Tricuspid regurgitation is usually secondary to right ventricular dilation [16] which may be due to left ventricular failure (the most common cause), right ventricular infarction, inferior myocardial infarction, [16] or cor pulmonale [16] Other causes of tricuspid regurgitation include carcinoid syndrome and myxomatous degeneration.
In humans it can be voluntary or involuntary, the latter being due to a small number of disorders. Regurgitation of a person's meals following ingestion is known as rumination syndrome , an uncommon and often misdiagnosed motility disorder that affects eating.
