Overview
Select Severe LVH · Preserved EF under Clinical controls → Hemodynamic state. The bold italic live label confirms the active selection. These are the preset’s teaching features; combined disease, rate and interventions can change the resulting numbers.
Severe concentric LV hypertrophy with preserved reference ejection fraction, impaired relaxation and elevated left-sided filling pressures. This selected nonobstructive phenotype has adequate resting forward flow and systemic blood pressure.
At HR 75 bpm and CO 5.25 L/min, the illustrative LV EDV of 112 mL and ESV of 42 mL give EF 62.5%. Preserved EF does not mean normal filling pressure.
Mean PAWP is 22 mmHg and LVEDP is 26 mmHg at reference loading; these are distinct pressure measurements, not interchangeable diagnostic cutoffs.
The schematic has severe concentric wall thickening and a nondilated LV cavity, without assumed systolic anterior mitral motion or dynamic LV outflow obstruction.
An illustrative low-pitched presystolic S4 accompanies effective organized atrial contraction. AF removes this sound and the organized atrial a wave.
The numeric geometry and pressure/flow response are teaching assumptions, not measured patient data. LVH alone does not identify its cause or establish clinical HFpEF.
