The apical pulse is a measure of cardiac function that is completed by placing a stethoscope at the apex of the heart and counting for one minute. It represents the opening and closing of the valves in the heart.
When the apical pulse is irregular, it is best to count for at least 1 minute to obtain an accurate rate. 1. Determining an apical pulse involves locating the point of maximal impulse (PMI), placing the bell or diaphragm of your stethoscope at this site, and listening for 1 minute.. To determine the pulse deficit, take the radial and the apical pulses simultaneously. 2. Position the patient either in a supine or a sitting position and expose the patient's sternum and the left side of the chest. 3. Using the appropriate anatomical landmarks, locate the radial and the apical pulses.
