Parasternal heave. A parasternal heave, lift, [1] or thrust [2] is a precordial impulse that may be felt (palpated) in patients with cardiac or respiratory disease. Precordial impulses are visible or palpable pulsations of the chest wall, which originate on the heart or the great vessels. [3]
The lever escapement, invented by the English clockmaker Thomas Mudge in 1754 (albeit first used in 1769), is a type of escapement that is used in almost all mechanical watches, as well as small mechanical non-pendulum clocks, alarm clocks, and kitchen timers. An escapement is a mechanical linkage that delivers impulses to the timepiece's ...
Echocardiography, cardiovascular MRI [ 1] Differential diagnosis. Athletic heart syndrome. Left ventricular hypertrophy ( LVH) is thickening of the heart muscle of the left ventricle of the heart, that is, left-sided ventricular hypertrophy and resulting increased left ventricular mass .
Livermorium. Livermorium is a synthetic chemical element; it has symbol Lv and atomic number 116. It is an extremely radioactive element that has only been created in a laboratory setting and has not been observed in nature. The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the ...
Accelerated idioventricular rhythm is a ventricular rhythm with a rate of between 40 and 120 beats per minute. Idioventricular means “relating to or affecting the cardiac ventricle alone” and refers to any ectopic ventricular arrhythmia. [1] Accelerated idioventricular arrhythmias are distinguished from ventricular rhythms with rates less ...
Ventricular dyssynchrony. In cardiology, ventricular dyssynchrony is a difference in the timing, or lack of synchrony, of contractions in different ventricles in the heart. Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure. [1] [2] [3]
e. In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object. If the initial momentum of an object is p1, and a subsequent momentum is p2, the object has received an impulse J : Momentum is a vector quantity, so impulse is also a vector quantity. Newton’s second law of motion states that the rate of ...
Left ventricular thrombus is a blood clot ( thrombus) in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). [1] [2] Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle. [3] The primary risk of LVT is the occurrence of cardiac embolism, [1] [4] in which the thrombus ...
