Hello,
With the question “Why does panic increase heart rate and blood pressure? ”, the doctor would like to answer as follows:
Blood pressure = Heart rate x Cardiac output. When the heart rate is fast, the blood pressure increases. When the body panic is a stress, the body secretes hormones that affect the cardiovascular system, the heart makes the heart beat faster, the respiratory system makes breathing faster, the blood vessels constrict the blood vessels.
If you still have questions about panic increasing heart rate, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
