A significant decrease in systolic blood pressure during exercise is most consistent with what, and what should be done?

• A. It indicates good cardiac output; continue with the planned intensity.
• B. It indicates excessive vasodilation; maintain intensity.
• C. It indicates improved oxygen delivery; increase intensity.
• D. It may indicate poor cardiac output; adjust exercise intensity.

Answer: (D)

When someone starts exercising, systolic blood pressure should rise as the heart pumps more blood to meet the muscles’ needs. A significant drop in systolic BP during activity suggests the heart cannot sustain the increased output, which points to poor cardiac output and possible myocardial ischemia or decompensation. That unsafe signal means you should pull back on the workload to protect perfusion and monitor closely, stopping or at least reducing intensity and reassessing before resuming. In short, a declining SBP with continued exercise indicates the need to adjust the exercise intensity rather than push harder.
