Which type of blood pressure is indicative of the heart's peak contraction force?

• A. Diastolic blood pressure
• B. Normal blood pressure
• C. Systolic blood pressure
• D. Pulsatile blood pressure

Answer: (C)

The correct answer is systolic blood pressure because it represents the maximum pressure in the arteries during the contraction of the heart, specifically when the ventricles pump blood out into the arteries. This peak contraction corresponds to the moment when the heart is actively working to send blood throughout the body, leading to the highest measurement observed in a blood pressure reading. In contrast, diastolic blood pressure measures the pressure in the arteries when the heart is at rest between beats, which is lower than systolic pressure. Normal blood pressure refers to a range of pressure values considered healthy and does not specify a peak contraction. Pulsatile blood pressure describes the rhythmic expansion and contraction of the arteries accompanying the heartbeat, but it is not a standard measure like systolic or diastolic blood pressure. Thus, systolic blood pressure is the most direct indicator of the force exerted by the heart during its contraction phase.
