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
See also Mitral regurgitation. Pulmonic regurgitation: the backflow of blood from the pulmonary artery into the right ventricle, owing to insufficiency of the pulmonic semilunar valve. Tricuspid regurgitation: the backflow of blood from the right ventricle into the right atrium, owing to imperfect functioning (insufficiency) of the tricuspid valve.
A Graham Steell murmur is a heart murmur typically associated with pulmonary regurgitation. [1] [2] It is a high pitched early diastolic murmur heard best at the left sternal edge in the second intercostal space with the patient in full inspiration, originally described in 1888. [citation needed]
Pulsus paradoxus can be caused by several physiologic mechanisms. Anatomically, these can be grouped into: [1] cardiac causes, pulmonary causes and; non-pulmonary and non-cardiac causes. Considered physiologically, pulsus paradoxus is caused by: [citation needed] decreased right heart functional reserve, e.g. myocardial infarction and tamponade,
Splitting of S2, also known as physiological split, normally occurs during inhalation because the decrease in intrathoracic pressure increases the time needed for pulmonary pressure to exceed that of the right ventricular pressure. A widely split S2 can be associated with several different cardiovascular conditions, and the split is sometimes ...

A mortgage point could cost 1% of your mortgage amount, which means about $5,000 on a $500,000 home loan, with each point lowering your interest rate by about 0.25%, depending on your lender and loan.
The relationship between the intra-pulmonary pressure and intra-pleural pressure is that the pressure becomes more negative during inspiration and allows air to get sucked in (Boyle's law) P vs V relationship and during expiration, the pressure becomes less negative (Note: still less than atmospheric pressure, also take note of the partial ...
