How is lvedp obtained
Web10 jun. 2024 · The LV waveform is derived from the aortic placement signal and the motor current. The optical sensor on the Impella heart pump senses aortic pressure (AoP). The Impella motor current recognizes pressure gradients between the aorta and left ventricle during the cardiac cycle. (ΔP (AO-LV)). LV pressure is represented by the equation: WebMy left atrium is enlarged and my left ventricular end diastolic pressure is 24 mmHg. >20 mmHg is considered diastolic heart failure. The high filling pressure in the left ventricle …
