The document discusses different pulse sites in the body. It defines a pulse as the wave of blood in the artery created by the contraction of the left ventricle during each cardiac cycle. There are peripheral pulses that can be felt over bony prominences like the carotid, radial, and popliteal arteries, and apical pulses that are monitored with a stethoscope over the heart apex. Key parameters of pulses include rate (bradycardia is under 60 beats/minute, tachycardia is over 100), and rhythm or time interval between beats. Common pulse sites that can be checked include the temporal, carotid, brachial, radial, femoral, popliteal, and dorsalis pedis arteries.
