The apical pulse is located on the chest near the heart. To take an apical pulse a stethoscope and a stop-watch or a clock with a second hand are needed. To locate the apical pulsation anatomical landmarks are used. First locate the first intercostal space (the space between the first and second rib) on the left side of the chest. Count down to the fifth intercostal space (between the fifth and sixth rib). Draw a straight line from the left nipple to the fifth intercostal space to identify the area of the apical pulse. Place the diaphragm (flat part) of the stethoscope on this point and count the heart beat for 60 seconds. The heart beat consists of two distinct sounds, lub-dub. Each lub-dub counts as one heart beat.
