Why does heart rate increase when scared

The ANS consists of the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system is responsible for the fight-or-flight response. This controls how the body reacts to situations that it perceives to be stressful or dangerous. When the sympathetic nervous system is active, bodily functions, such as digestion, stop temporarily, and heart rate and blood pressure increase.

The parasympathetic nervous system, also known as the rest and digest system , maintains bodily functions, such as digestion, when a person is resting.

It will also reduce heart rate and blood pressure after a fight-or-flight response. The parasympathetic system and sympathetic system work together to maintain homeostasis — which is when the body is in a balanced state. Triggers and responses to anxiety disorders depend on individual experiences and the type of anxiety disorder a person has.

According to NAMI , examples of anxiety disorders include:. For instance, social anxiety disorder causes more psychological responses, such as intense worrying and irrational thoughts.

In contrast, panic disorder causes more physical symptoms, such as heart palpitations. According to NAMI , there are different types of anxiety disorders, so symptoms depend on the individual and the type of anxiety they have. However, all types of anxiety present several key symptoms. Heart palpitations can be a symptom of anxiety and not a major cause for concern — providing the person is aware of the trigger, and the palpitations stop when the anxiety subsides.

An article in the American Family Physician journal suggests palpitations due to anxiety are more common in people who experience a lot of daily irritation, and those who are sensitive to sensations in their body. To diagnose anxiety palpitations, a doctor will begin with a screening questionnaire.

This will help them identify people who are likely to have palpitations from anxiety. A doctor will refer anyone who passes a certain score for monitoring. A doctor may consider using a Holter monitor if a person experiences palpitations on a daily basis. The person must wear the Holter device throughout the monitoring period and record any symptoms.

A transtelephonic event monitor is smaller than a Holter monitor and does not run for the whole period. Although the person wears it continuously, they operate the monitor manually.

Some types of transtelephonic monitors require a person to hold it against their chest only when they think they are experiencing palpitations. The results of these assessments must eliminate all other potential causes before a doctor can make a diagnosis of anxiety-induced heart palpitations. Once a doctor confirms that an anxiety disorder is the cause of the heart palpitations, they may refer a person to a therapist for treatment. According to the OWH , options may include:.

Treatment plans may use a combination of these strategies to target symptoms of anxiety, including heart palpitations. According to NAMI , a therapist will help a person identify the causes of their anxiety attacks and find ways to work through them.
