The document describes several types of arterial pulses:
1) Anacrotic pulses have a low amplitude with a slow rise and fall and are seen in aortic stenosis. Dicrotic pulses have two peaks, one in systole and one in diastole, and are caused by low stroke volume and decreased peripheral resistance.
2) Collapsing or water hammer pulses have a rapid upstroke and downstroke due to increased stroke volume and decreased peripheral resistance, seen in aortic regurgitation and other conditions.
3) Pulsus bisferiens has two peaks in systole, best felt in the brachial and femoral arteries and caused by conditions like aortic stenosis and regurgitation.
