Can ADHD Cause Heart Palpitations?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and impulsivity that can affect daily functioning. This article explores the relationship between ADHD and heart palpitations, including how symptoms and treatments may influence them.

What Are Heart Palpitations?

Heart palpitations are feelings that your heart is beating too fast, too hard, or irregularly. These sensations can manifest as a fluttering, pounding, or flip-flopping in the chest, and sometimes in the throat or neck. While often harmless, they can be unsettling and commonly occur in many individuals.

Factors unrelated to ADHD can also trigger heart palpitations. Common causes include emotional states like stress, anxiety, fear, or panic. Lifestyle choices also play a role, with strenuous exercise, high caffeine intake, alcohol consumption, and nicotine use being common triggers. Other causes include lack of sleep, dehydration, fever, and certain over-the-counter medications like decongestants.

How ADHD Symptoms Can Influence Palpitations

ADHD itself does not directly cause heart palpitations. However, living with ADHD can indirectly contribute to their occurrence. Difficulties with organization, time management, and emotional regulation often lead to increased stress and anxiety. These heightened emotional states can trigger the body’s fight-or-flight response, releasing hormones like adrenaline that increase heart rate, leading to palpitations.

Sleep disturbances are common in individuals with ADHD, including difficulty falling asleep or restless sleep patterns. Insufficient or poor-quality sleep places additional stress on the body, which can manifest as palpitations. Some individuals with ADHD may also consume more caffeine to improve focus or combat fatigue. Excessive consumption of caffeine is a well-known stimulant that can directly induce heart palpitations.

ADHD Medications and Heart Palpitations

Certain medications prescribed for ADHD can directly impact the cardiovascular system and cause heart palpitations. Stimulant medications, such as methylphenidate and amphetamines, are common for ADHD. These medications work by increasing neurotransmitter levels like norepinephrine and dopamine in the brain, affecting the heart.

Stimulant medications typically cause increased heart rate and blood pressure. While often mild, these changes can be more pronounced in some, leading to palpitations. Healthcare providers should monitor heart rate and blood pressure when these medications are prescribed.

Non-stimulant medications for ADHD, such as atomoxetine, can also have cardiovascular effects, including increased heart rate and blood pressure, similar to stimulants. Another non-stimulant, guanfacine, typically leads to a decrease in blood pressure. Individuals should discuss any new or worsening heart symptoms with their doctor, especially when starting or adjusting ADHD medication.

When to Talk to Your Doctor

While most heart palpitations are not serious, seek medical advice if they are frequent, prolonged, or accompanied by other concerning symptoms. Seek immediate medical evaluation if palpitations occur with chest pain, shortness of breath, dizziness, or fainting. These symptoms could indicate a more serious underlying heart condition.

Consult a healthcare provider if palpitations are new, worsening, or if you have a known heart condition or a family history of heart problems. Your doctor will conduct a medical history and physical examination to determine the underlying cause. This evaluation helps ensure appropriate management and rule out any potential cardiac issues, particularly if you are taking ADHD medication.
