Q

Implications of a left ventricular impulse feeling too weak

A

Pressure overload in left ventricle. Implies blockage downstream

Q

What can be inferred from the patient’s carotid pressure vs left ventricular pressure?

A

There is a blockage between the left ventricle and the aorta/carotid.

Need to think of a place between the LV and aorta.

The most likely is a stenosis (block) of the aortic valve.
