When irregular heart rhythm is present, what should you document with blood pressure measurement?

• A. Note rhythm and any irregularity; regularity assessment.
• B. Do not record rhythm to avoid confusion.
• C. Exclude BP measurement due to irregular rhythm.
• D. Use a single measurement and proceed.

Answer: (A)

When a heart rhythm is irregular, you can’t ignore that information for BP interpretation. The key idea is to document both the rhythm and any irregularity, and to assess whether the rhythm is regular or irregular. This note helps explain why readings might vary from beat to beat and guides steps like taking multiple measurements and averaging them. Recording the rhythm also alerts clinicians to potential conditions such as atrial fibrillation that may require different management. Not recording rhythm, excluding BP because of irregular rhythm, or relying on a single reading would miss important cardiac data and could lead to misinterpretation.
