What Causes Heart Palpitations at Night?

What Causes Heart Palpitations at Night?

Heart palpitations at night may feel like racing, pounding, fluttering, or skipped heartbeats. They are often harmless, but repeated or prolonged episodes should not automatically be ignored.

Palpitations can also feel more noticeable when you are resting quietly in bed, when there are fewer distractions.

🌙 Common Nighttime Triggers

Frequent triggers include:

• Lack of sleep
• Stress or anxiety
• Alcohol
• Caffeine
• Nicotine
• Strenuous evening exercise
• Certain medications or stimulants

Premature heartbeats can also produce the sensation of a sudden extra beat followed by a stronger heartbeat.

😴 Could Sleep Problems Be Involved?

Poor sleep may increase awareness of palpitations, while sleep apnea is associated with abnormal heart rhythms in some patients.

Discuss sleep evaluation when nighttime palpitations occur together with:

• Loud snoring
• Gasping during sleep
• Morning headaches
• Daytime sleepiness
• Difficult-to-control high blood pressure

🩺 Other Medical Causes to Consider

Recurring palpitations may sometimes be related to:

• Anemia
• Overactive thyroid
• Electrolyte abnormalities
• Heart valve disease
• Atrial fibrillation
• Other abnormal heart rhythms

Blood tests and an ECG can help identify some of these causes.

💓 When Should You Get Checked?

Arrange a medical evaluation when palpitations:

• Keep returning
• Last longer than a few minutes
• Are becoming more frequent
• Wake you repeatedly from sleep
• Occur with dizziness or unusual breathlessness
• Develop when you already have heart disease

An ECG is usually the first rhythm test. If episodes occur only occasionally, a Holter or longer-term rhythm monitor may be needed to record the heartbeat when symptoms happen.

🏥 Getting Checked in Seoul

An internal medicine or cardiology clinic can review your symptoms and decide whether additional testing is necessary.

Bring:

• A record of when the palpitations occur
• Approximate duration of each episode
• Your medication and supplement list
• Information about caffeine and alcohol
• Previous ECG or heart-test results

Note whether symptoms begin after lying down, after eating, after drinking alcohol, or during sleep. This pattern can help guide further testing.

🚑 When to Call 119

Seek emergency care if palpitations do not stop and occur with:

• Chest pain or pressure
• Severe shortness of breath
• Fainting or near-fainting
• Severe dizziness or weakness
• Loss of consciousness

These symptoms can accompany a significant heart rhythm problem and require urgent assessment. In Seoul, 119 is the emergency medical number.

✨ Final Thoughts

Nighttime palpitations are often related to stress, poor sleep, caffeine, alcohol, nicotine, or occasional extra heartbeats, but thyroid problems, anemia, sleep apnea, and arrhythmias can also be responsible.

If the episodes are frequent, prolonged, or accompanied by other symptoms, record when they happen and arrange a medical evaluation rather than relying on symptoms alone.
