What does the apical-radial pulse measure?

The apical-radial pulse is a method used to assess both the apical pulse, which is measured at the heart, and the radial pulse, which is measured at the wrist. By measuring these two pulses simultaneously, healthcare providers can determine if there is a discrepancy between heartbeats at the apex (the top of the heart) and those felt at the radial artery. This assessment is crucial for identifying conditions like pulse deficit, which may indicate issues such as arrhythmias or inadequate cardiac output. The simultaneous measurement allows practitioners to ensure they are accurately capturing the heart's performance in relation to peripheral circulation, which is vital for patient assessment.
