What is a heart palpitation?
If you feel like your heart has suddenly skipped a beat, it may mean you’ve had a heart palpitation. Heart palpitations can be best described as a feeling that your heart is beating too hard or too fast. You may feel that your heart is skipping a beat, fluttering rapidly, or beating extremely fast. You may also feel that your heart is producing heavy, pounding beats.
Palpitations aren’t always harmful, but they can be worrisome if you’ve never experienced them before. For many people, the unusual beats will end and go away entirely on their own. Sometimes, however, medical treatment is necessary to prevent them from occurring again in the future.
Symptoms of heart palpitations are different for everyone who experiences them. For many people, the most common symptoms feel as if your heart is:
- skipping beats
- fluttering rapidly
- beating too fast
- beating harder than usual
Heart palpitations can occur when you’re standing, sitting, or lying down. You may feel these unusual sensations in your chest, neck, or even your throat.
You may only experience one episode in your life, or you may experience palpitations regularly. Most episodes will end on their own, even without treatment.
However, some symptoms are a sign of a more serious condition. If you experience palpitations and any of the following symptoms, you should seek emergency medical attention:
- chest pain or discomfort
- severe shortness of breath or difficulty breathing
- dizziness and nausea
The cause of heart palpitations isn’t always known. These harmless heart hiccups can happen from time to time without a real explanation.
Some common causes can be identified in people who have heart palpations, though. The causes can be divided into two primary categories: non-heart-related causes and heart-related causes.
The primary non-heart-related causes include:
- intense emotional feelings, including stress or fear
- drinking too much caffeine or alcohol, or consuming too much nicotine
- use of illegal substances, including cocaine, amphetamines, and heroin
- hormonal changes as a result of pregnancy, menopause, or menstruation
- vigorous physical activity, including strenuous exercise
- herbal or nutritional supplements
- certain medications, including diet pills, decongestants, or cold and cough medicines, and asthma inhalers with stimulants
- illnesses or conditions, including fever, dehydration, abnormal electrolyte levels
- medical conditions, including low blood sugar, low blood pressure, and thyroid disease
- food sensitivities or allergies
The primary heart-related causes include:
Risk factors for heart palpitations are closely connected to the possible causes. For example, one common cause for heart palpitations is intense emotional reactions like fear and stress. People with a high level of stress and anxiety are at greater risk for experiencing palpitations.
Other risk factors for heart palpitations include:
- an anxiety disorder
- a history of panic attacks
- pregnancy or hormonal changes
- taking medications with stimulants, such as asthma inhalers, cough suppressants, and cold medicine
- having a diagnosed heart condition that increases your risk, such as coronary heart disease, arrhythmia, or a heart defect
- hyperthyroidism (overactive thyroid)
In many cases, palpitations are harmless, but they can be worrisome. A cause may be unknown, and tests might not return any results.
If you continue to experience palpitations or if you’d like to be sure an underlying problem isn’t causing them, make an appointment to see your doctor.
At your appointment, your doctor will conduct a full physical exam and ask about your medical history. If they suspect something might be causing these symptoms, they’ll order tests.
These tests can be used to help identify a cause for heart palpitations:
- Blood tests. Changes in your blood may help your doctor identify possible problems.
- Electrocardiogram (EKG). This test records your heart’s electrical signals for a period of time. In some cases, you may have an EKG while you’re exercising. This is known as a stress test.
- Holter monitoring. This type of test requires you to wear a monitor for 24 to 48 hours. The monitor records your heart the entire time. This longer time frame gives your doctor a broader window of your heart’s activities.
- Event recording. If the palpitations are too sporadic for continuous monitoring, your doctor may suggest another type of device. This one is worn continuously. You’ll use a handheld device to begin recording as soon as you start experiencing symptoms.
Treatment for heart palpitations depends on the cause. For most people, palpitations will go away on their own, without any treatment. For others, treating the underlying cause of the palpitations can help stop or prevent them.
If anxiety or stress leads to the sensation, look for ways to reduce your worry. This may include activities such as meditation, journaling, yoga, or tai chi. If these techniques aren’t enough, work with your doctor to find a medication that can ease symptoms of anxiety.
Cut out problematic food and substances
Drugs, medications, and even foods can lead to palpitations. If you identify a substance that’s causing palpitations or sensitivities, remove it from your diet to stop palpitations.
For example, cigarette smoking can lead to palpitations. If you discover that you have more heart palpitations when you smoke, stop smoking for a period of time and see if the sensation ends. We reached out to readers for real and practical tips to stop smoking.
Take care of your body
Stay hydrated, eat well, and get regular exercise. These components of a healthy lifestyle can also reduce your risk for heart palpitations.
Find a cause-specific treatment
If your heart palpitations are the result of a condition or disease, your doctor will work with you to find an appropriate treatment. These treatment options may include medications and procedures.
Heart palpitations aren’t usually a reason for concern. If you experience the sensation of a fluttering, rapid, or pounding heart, know that most people won’t need treatment. The palpitations will likely go away on their own without any lasting issues.
However, if these sensations continue or if you’re worried they may be a sign of an underlying health issue, see your doctor. Tests can help your doctor quickly rule out any possible serious issues so that you can find a diagnosis and a treatment.
