Understanding Heart Palpitations: What They Are and Why They Happen

Heart palpitations are sensations where you feel your heartbeat in your chest, throat, or neck. You might notice your heart racing, skipping beats, or beating irregularly. Many people describe palpitations as feeling like their heart is pounding, fluttering, or doing flip-flops inside their chest. These sensations can last for just a few seconds or continue for several minutes.

According to the American Heart Association, heart palpitations are among the most common reasons people visit their doctors with heart-related concerns. Research shows that about 16% of the general population experiences palpitations at some point in their lives. Despite how alarming they feel, palpitations are not always a sign of a serious heart condition.

Palpitations occur when your heart's electrical system misfires or when your heart works harder than normal. Your heart normally beats 60 to 100 times per minute when you're at rest. When something triggers your heart to beat faster, harder, or irregularly, you become aware of the beating—which is what you feel as a palpitation.

Different types of palpitations feel different to different people. Some people feel a single strong beat followed by a pause. Others experience a sensation of rapid fluttering that feels like a bird trapped in their chest. Some describe it as their heart doing a somersault. The specific sensation depends on what's causing the irregular rhythm.

Understanding what palpitations are is the first step toward learning whether yours require medical attention. The information in a heart palpitations guide can help you recognize what you're experiencing and understand the difference between palpitations caused by everyday factors and those that might warrant a conversation with your doctor.

Practical Takeaway: Keep a simple record of when you feel palpitations—what time of day, what you were doing, and how long they lasted. This information can be helpful if you discuss your experiences with a healthcare provider.

Common Triggers and Causes of Heart Palpitations

Many different factors can trigger heart palpitations, ranging from temporary and harmless to more serious. One of the most common triggers is caffeine. Caffeine is a stimulant found in coffee, tea, energy drinks, chocolate, and some medications. Studies show that caffeine can increase heart rate and trigger palpitations in sensitive individuals. A single cup of coffee contains 95 to 200 milligrams of caffeine, which is enough to cause palpitations in some people.

Physical stress and intense exercise can also trigger palpitations. When you exercise, your heart rate naturally increases to pump more blood and oxygen to your muscles. In some cases, especially during very intense workouts, you might become aware of your heart beating strongly. For most people, this is a normal response and not a cause for concern.

Emotional stress and anxiety are significant palpitation triggers. When you're anxious or stressed, your body releases adrenaline, which causes your heart to beat faster and harder. This is part of your body's natural fight-or-flight response. People with anxiety disorders report palpitations more frequently than the general population. The worry about palpitations can sometimes cause additional stress, creating a cycle where anxiety triggers palpitations, which causes more anxiety.

Hormone changes related to menstruation, pregnancy, and menopause can trigger palpitations. During the menstrual cycle, fluctuating estrogen levels may increase palpitation episodes. Many women report increased palpitations during perimenopause and menopause. Pregnancy also causes the heart to work harder, which can lead to noticeable palpitations.

Other common triggers include dehydration, lack of sleep, smoking, alcohol consumption, and certain medications. Dehydration reduces the amount of blood in your body, forcing your heart to pump harder to deliver oxygen to your tissues. Getting less than 6 hours of sleep per night can disrupt your heart's rhythm. Nicotine and alcohol both stimulate the heart and increase palpitation risk.

Practical Takeaway: Consider keeping a palpitations diary for one to two weeks. Note what you ate and drank, your activity level, your stress level, and when palpitations occurred. Patterns may emerge that point to your personal triggers, allowing you to make informed decisions about lifestyle changes.

When Palpitations May Require Medical Attention

While many palpitations are harmless, certain situations warrant a conversation with a healthcare provider. If your palpitations are new and happen frequently, if they last longer than a few minutes, or if they occur alongside other symptoms, medical evaluation is important. Understanding which palpitations might signal something that needs attention helps you make informed decisions about your health.

You should seek medical evaluation if you experience palpitations along with chest pain or pressure. Chest discomfort during palpitations could indicate a heart condition that requires diagnosis and treatment. Similarly, palpitations accompanied by shortness of breath, dizziness, lightheadedness, or fainting are concerning signs that warrant prompt medical attention. These symptoms together suggest your heart might not be pumping blood effectively to your brain and body.

If you have a personal or family history of heart disease, irregular heartbeat (arrhythmia), or sudden cardiac death, palpitations should be evaluated by a doctor. Your medical history increases the likelihood that palpitations signal an underlying heart condition. People with high blood pressure, diabetes, or thyroid disorders should also have palpitations evaluated, as these conditions increase arrhythmia risk.

Palpitations that wake you from sleep, happen during physical activity when you haven't increased your exercise intensity, or occur at rest without an obvious trigger may indicate a cardiac issue. Additionally, if palpitations change in character—such as becoming more frequent, lasting longer, or feeling different than before—medical evaluation is warranted.

A heart palpitations information guide can help you understand which symptoms and situations suggest the need for medical evaluation. Healthcare providers use various tests to diagnose what's causing palpitations, including electrocardiograms (EKGs), holter monitors, echocardiograms, and blood tests. These tests help determine whether palpitations are benign or indicate a heart rhythm disorder requiring treatment.

Practical Takeaway: Create a list of specific symptoms you experience with palpitations—chest pain, shortness of breath, dizziness, or fainting—and bring this list to your doctor's appointment. This specific information helps your healthcare provider assess your condition more accurately.

Lifestyle Changes That May Reduce Palpitations

Many people find that making lifestyle adjustments reduces the frequency and severity of their palpitations. One of the most impactful changes involves limiting or eliminating caffeine consumption. Studies show that reducing caffeine intake noticeably decreases palpitation episodes in caffeine-sensitive individuals. If you consume significant amounts of caffeine daily, reducing gradually rather than stopping abruptly prevents withdrawal headaches while allowing your body to adjust.

Managing stress through various relaxation techniques can reduce palpitations triggered by anxiety and emotional tension. Deep breathing exercises, where you breathe slowly and deeply through your nose and exhale through your mouth, activate your parasympathetic nervous system—the part of your nervous system that helps your body relax. Progressive muscle relaxation, where you tense and then release different muscle groups, is another evidence-based technique. Meditation, yoga, and tai chi have all been shown in research to lower stress levels and reduce palpitation frequency.

Regular physical activity strengthens your heart and helps it function more efficiently. The American Heart Association recommends 150 minutes of moderate-intensity aerobic activity per week. Moderate-intensity activity means you're moving enough that you can talk but not sing during exercise. Walking, swimming, cycling, and dancing are all examples. Regular exercise reduces resting heart rate, meaning your heart doesn't have to work as hard during daily activities.

Improving sleep quality significantly impacts heart health and palpitation frequency. Adults should aim for 7 to 9 hours of sleep nightly. Creating a consistent sleep schedule—going to bed and waking at the same time daily—helps regulate your body's internal clock. Avoiding screens one to two hours before bed, keeping your bedroom cool and dark, and limiting caffeine after 2 PM all promote better sleep.

Maintaining healthy weight, limiting alcohol consumption, and avoiding smoking also help reduce palpitations. Excess weight forces your heart to work harder to pump blood throughout your body. Alcohol triggers arrhythmias in
