Rotational pauses: signs, symptoms, and causes

The narrow segment of the aorta anterior to where the left subclavian artery originates restricts blood flow and causes a drop in blood pressure distal to the stenosis. The pulse wave arrives slower than the left-hand side, and the amplitude of the left and right pulse is also different

Description

Is the difference between the time to catch the pulse when the pulse is rotated on both left and right sides at the same time.

Cause

Aortic stenosis.

Stenosis of the subclavian artery due to an aneurysm.

Mechanism

The narrow segment of the aorta anterior to where the left subclavian artery originates restricts blood flow and causes a drop in blood pressure distal to the stenosis.

The pulse wave arrives slower than the left-hand side, and the amplitude of the left and right pulse is also different.
