The cardiac impulse is the vibration resulting from the heart rotating, moving forward and striking against the chest wall during systole . The PMI is not the apex of the heart but is on the precordium not far from it . </P> <P> The normal apex beat can be palpated in the precordium left 5th intercostal space, half inch medial to the left midclavicular line . In children the apex beat occurs in the fourth rib interspace medial to the nipple . The apex beat may also be found at abnormal locations; in many cases of dextrocardia, the apex beat may be felt on the right side . </P> <Ul> <Li> <P> Algorithm for classification of the apex beat characters </P> </Li> </Ul>
