Heart palpitations feel like your heart is pounding, fluttering, skipping a beat or doing a flip in your chest. Heart palpitations at night usually aren’t harmful. Many factors, including alcohol, caffeine, nicotine, stress or hormones can cause them. Less often, they result from a health condition such as heart disease or a thyroid disorder.
Heart palpitations feel like your heart is pounding, racing or beating quickly. It can also feel like your heart is skipping a beat or like you have an extra heartbeat. Palpitations make you aware of your heart rate. You may feel your heart beating in your chest, but it’s also common to feel it beating in your neck or throat.
Heart palpitations can happen anytime, including at night or when you’re resting during the day. They can be scary, but they aren’t usually dangerous. Many people have the same heart palpitations during the day but don’t notice because they’re busy.
Less commonly, heart palpitations at night can be signs of a serious health condition, such as arrhythmia (abnormal heart rhythm). If your heart often races when you lie down, you should see your provider for an examination. Get help right away if you have palpitations and trouble breathing or chest pain.

Heart palpitations are very common. They happen to many people throughout the day. But you’re more likely to notice heart palpitations when you aren’t distracted. You might sense them when you’re sitting still, resting or lying down.
When you lay down you may feel:
Usually, heart palpitations are harmless and don’t result from an underlying health problem. They happen when the heart beats out of rhythm or contracts (beats) too soon. Providers call this a premature ventricular contraction (PVC) or premature atrial contraction (PAC). Nearly everyone has a PVC or PAC from time to time. But not everyone feels them.
Some people get heart palpitations when lying down because of the position in which they sleep. Sleeping hunched over on your side can increase pressure inside your body, causing palpitations. Many other common causes of heart palpitations include:

Your provider will ask about your symptoms and listen to your heart. They may recommend a blood test (complete blood count or CBC) to look for anemia or infection. A blood test can also show signs of a vitamin deficiency or a problem with your thyroid.
To monitor your heart rate, they may do an electrocardiogram (EKG or ECG). This test measures your heart rate using sensors that attach to your skin. They may ask you to lie down during the test, which usually takes about 15 minutes.
Many times, an EKG doesn’t detect heart palpitations. You might not have an irregular heartbeat during the test. If this happens, your provider may recommend an ambulatory electrocardiogram such as a Holter monitor. You wear this device for up to a week as you go about your daily activities. It records your heart rate (and any irregular heartbeats) and stores the information for your provider to review.
Most of the time, heart palpitations at night don’t require treatment, especially if they only happen occasionally. You may be able to relieve heart palpitations at night yourself. If your heart is racing at night, you should:

Most people with heart palpitations at night don’t require treatment. If palpitations happen from time to time, they aren’t usually dangerous. Many people find relief from heart palpitations at night after making changes to their diet or lifestyle. These changes may include avoiding alcohol and managing stress.
If you have heart palpitations that result from a heart problem, thyroid disease or other health condition, talk to your provider about your prognosis. To relieve your symptoms, your provider will treat the condition that’s causing them.
If you have frequent heart palpitations when resting or lying down, you should schedule a visit with your provider. Most of the time, heart palpitations at night aren’t harmful. But it’s important to see your provider to be sure they aren’t signs of a serious health problem.
