What is the normal left ventricular systolic and diastolic pressure range?

• A. 100-140 mmHg (systolic); 3-12 mmHg (diastolic)
• B. 120-160 mmHg (systolic); 5-15 mmHg (diastolic)
• C. 80-120 mmHg (systolic); 0-5 mmHg (diastolic)
• D. 140-180 mmHg (systolic); 10-20 mmHg (diastolic)

Answer: (A)

Normal left ventricular systolic pressure reflects the peak pressure during contraction to eject blood into the aorta, which is about 120 mmHg in a healthy adult. The diastolic pressure in the left ventricle, when the heart is relaxed, is much lower—typically around 3 to 12 mmHg. So a normal range is roughly 100–140 mmHg for systolic and 3–12 mmHg for diastolic. This matches the given option. The other ranges either exaggerate the systolic pressure or place the diastolic pressure outside the usual LV diastolic window, making them less accurate representations of normal LV pressures.
