Inequality in the amplitude of the peripheral pulses may result from:
- Obstructive arterial diseases, most commonly atherosclerosis
- Aortic dissection
- Aortic aneurysm
- Takayasu disease
- Coarctation of the aorta
- Supravalvular aortic stenosis in which the right carotid, brachial, and radial pulses are larger in amplitude and volume than those on the left side because of the preferential streaming of the jet toward the innominate artery.
