Answer:

a high cardiac output and high peripheral resistance

Explanation:

Two factors affect the strength of the blood and consequently the blood pressure: cardiac output and peripheral resistance.

However, increased heart rate results in increased cardiac output, which increases blood pressure, leading to hypertension.
