Yes. The fight-or-flight response—your body’s automatic reaction to a perceived threat—can definitely cause heart palpitations.​

Here’s why:

• When the brain senses danger, the sympathetic nervous system is activated.
• This triggers the release of adrenaline (epinephrine) and noradrenaline, stress hormones that prepare your body to respond quickly.
• These hormones increase heart rate, contractility, and force of each heartbeat to pump more blood to muscles and vital organs.
• As a result, you may feel heart palpitations—the sensation of your heart pounding, fluttering, or skipping beats.

This reaction is normal and usually subsides once the perceived threat passes. However, frequent or prolonged palpitations might indicate anxiety, chronic stress, or an underlying heart condition, in which case a medical evaluation is recommended.
Would you like me to give you a list of physical symptoms caused by the fight-or-flight response (besides palpitations) so you can compare?
