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 ...
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.
While the number and severity of symptoms vary among individuals, repetitive regurgitation of undigested food (known as rumination) after the start of a meal is always present. [2] [3] In some individuals, the regurgitation is small, occurring over a long period of time following ingestion, and can be rechewed and swallowed. In others, the ...
In some cases, a person with GERD symptoms can manage them by taking over-the-counter drugs. [50] [51] [52] This is often safer and less expensive than taking prescription drugs. [50] Some guidelines recommend trying to treat symptoms with an H 2 antagonist before using a proton-pump inhibitor because of cost and safety concerns. [50]
One may hear the systolic component at the left infraclavicular region and the back. This is due to the stenosis. One may hear the diastolic component over the chest wall. This is due to blood flow through collateral vessels. Acute severe aortic regurgitation may present with a three phase murmur. First, a midsystolic murmur followed by S2.
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 ...
Water spouting is a sideshow regurgitation act, in which a performance artist drinks a large amount of fluid, such as water, and regurgitates it in a controlled manner with muscle control. Typically, the act includes an element of stage magic in the transformation of the fluid; for example, ingesting water and regurgitating it as a stream of ...
Professional regurgitation is the act of controlled regurgitation. The act consists of swallowing and regurgitating various unusual objects. The objects may consist of anything from live animals (live aquatic: Mac Norton ; and live mice: The Great Waldo ), [ 1 ] to light bulbs, billiard balls ( Stevie Starr ) and kerosene ( Hadji Ali ).
