When do you check the apical pulse instead of radial pulse?

The apical pulse is checked instead of the radial pulse in the following situations:

1. Arrhythmias: When there is an irregular heart rate or rhythm, the apical pulse can provide more accurate information about the heart's activity compared to the radial pulse, which can be influenced by factors such as vessel tone and peripheral circulation.

2. Bradycardia: In cases of a slow heart rate (below 60 beats per minute), the radial pulse may be weak or difficult to palpate. Checking the apical pulse can help determine the exact heart rate and assess for any underlying bradyarrhythmias.

3. Weak Peripheral Pulses: In conditions where peripheral pulses are weak or absent, such as in cases of shock, hypotension, or peripheral vascular disease, the apical pulse can provide a reliable indication of the heart's activity.

4. Cardiac Conditions: Certain cardiac conditions, such as aortic stenosis or mitral regurgitation, may affect the accuracy and reliability of the radial pulse. In such cases, the apical pulse provides a more direct assessment of the heart's function and hemodynamic status.

5. Pediatric and Neonatal Patients: In infants and young children, the radial pulse can be difficult to palpate, especially in newborns and premature infants. The apical pulse is commonly used to assess the heart rate and rhythm in pediatric populations.

6. Obesity: In obese individuals, the radial pulse may be more difficult to locate due to increased subcutaneous tissue. Checking the apical pulse can provide a more accurate assessment of the heart rate in such cases.

It is important to note that while the apical pulse provides valuable information about the heart's activity, it is not a substitute for a complete cardiovascular assessment, which may include additional tests and procedures as deemed necessary by a healthcare professional.
