David Littmann (July 28, 1906 – January 1, 1981) was an American cardiologist and Harvard Medical School professor and researcher. [1] The name Littmann is well known in the medical field for the patented Littmann Stethoscope reputed for its acoustic performances for auscultation .
The stethoscope is a medical device for auscultation, or listening to internal sounds of an animal or human body.It typically has a small disc-shaped resonator that is placed against the skin, with either one or two tubes connected to two earpieces.
Ultrasonography (US) inherently provides capability for computer-aided auscultation, and portable US, especially portable echocardiography, replaces some stethoscope auscultation (especially in cardiology), although not nearly all of it (stethoscopes are still essential in basic checkups, listening to bowel sounds, and other primary care contexts).
The first heart sound, or S 1, forms the "lub" of "lub-dub" and is composed of components M 1 (mitral valve closure) and T 1 (tricuspid valve closure). Normally M 1 precedes T 1 slightly. It is caused by the closure of the atrioventricular valves , i.e. tricuspid and mitral (bicuspid), at the beginning of ventricular contraction, or systole .
The cardiovascular examination is a portion of the physical examination that involves evaluation of the cardiovascular system. The exact contents of the examination will vary depending on the presenting complaint but a complete examination will involve the heart (cardiac examination), lungs (pulmonary examination), belly (abdominal examination) and the blood vessels (peripheral vascular ...
The pericardium is a double-walled sac around the heart.The inner and outer (visceral and parietal, respectively) layers are normally lubricated by a small amount of pericardial fluid, but the inflammation of pericardium causes the walls to rub against each other with audible friction.
