In patients with normal ER does septal or LV filling pressures.
Lateral tiisue E/e' or e'/a' best corellation with normal EF. E/e' ratio is not accurate as an index of filling pressures in normal subjects or in patients with heavy MAC, MV disease and constrictive pericarditis.

Mitral E wave velocity is expected to be low in MS. (T or F)
False. In mitral stenosis, the peak velocity of the mitral E wave is expected to be high
Strain Rate
SR = (V1 − V2)/L
strain rate (SR) is defined as the change in velocity between two points divided by the distance between the two points at the end of systole (L).
