What is the target mean arterial pressure (MAP) when treating bradycardia?

• A. MAP should be ≥ 55 mmHg.
• B. MAP should be ≥ 65 mmHg.
• C. MAP should be ≥ 75 mmHg.
• D. MAP should be ≥ 85 mmHg.

Answer: (B)

Maintaining adequate perfusion is the goal when treating bradycardia, and the target MAP is about 65 mmHg. This level is generally sufficient to ensure cerebral and coronary blood flow in adults, even when the heart rate is low. Because bradycardia can cut cardiac output, clinicians use vasopressors or pacing to lift MAP to around 65 or higher, keeping organs well perfused as the underlying rhythm issue is addressed. Targeting 65 mmHg strikes a balance between avoiding hypoperfusion and avoiding unnecessary vasopressor stress.

The other options don’t fit as well because a MAP of 55 mmHg risks inadequate organ perfusion, while targets of 75 or 85 mmHg are typically higher than needed for standard bradycardia management unless there are specific circumstances (like certain hypertensive patients or ongoing shock) that require a higher threshold.
