Heart Palpitations: When to Go to the ER (Vaping, Coffee, Anxiety)

A third coffee before noon, a vape that never leaves your hand in traffic, short sleep before an exam or a deadline — then suddenly you feel your heart pounding in your chest or neck, or it seems to skip a beat and catch up. It's a frightening feeling, but in most cases it isn't a sign of heart disease. This guide explains what palpitations are, the most common causes, how to ease them, and the few warning signs that mean you need the ER now.

What are heart palpitations, and are they dangerous?

Palpitations are when your heartbeat suddenly becomes noticeable and uncomfortable. You may feel it in your chest, neck or throat, and it can last seconds, minutes or longer. Your heart may feel like it is:

• Racing or beating very fast.
• Irregular, with skipped or extra beats.
• Pounding or thumping.
• Fluttering.

According to the NHS, palpitations are common and rarely a sign of anything serious. Common causes include stress, anxiety and panic attacks; caffeine in coffee, tea and energy drinks; nicotine from cigarettes and vapes; alcohol; lack of sleep; dehydration; fever; strenuous exercise; some medicines (check the leaflet); and hormonal changes in pregnancy and the menopause. Less often, they're caused by anaemia, an overactive thyroid, a heart rhythm problem or another heart condition.

Usually harmless, see a doctor today, or call 911?

When should you go to the ER for heart palpitations?

Palpitations on their own are rarely an emergency. What changes the picture is what comes with them, and whether they stop.

Call 911 for

• Palpitations with chest pain, pressure or tightness, or pain spreading to the arm, jaw or back.
• Palpitations with shortness of breath.
• Fainting or blacking out, or feeling like you're about to faint.
• Palpitations that don't go away.

The NHS advises: don't drive yourself to the emergency department; ask someone to take you or call an ambulance, and bring your medicines.

Go to the ER now

• Palpitations after a large amount of caffeine or energy drinks, with vomiting, severe shakiness or confusion.
• Palpitations after recreational drugs or taking too much of a medicine.
• Palpitations with severe dizziness, a cold sweat or feeling very unwell.
• An episode in someone with a known heart condition that feels different from usual.

Urgent care or a doctor the same day

• Palpitations with chest pain, breathlessness or fainting that have now stopped.
• Episodes that last more than a few minutes, keep coming back or are getting more frequent.
• You have a heart condition, or a family history of heart problems or of a relative dying suddenly under 40.
• Palpitations with marked tiredness or paleness, or with weight loss, sweating and shaky hands.

Usually fine at home

• A brief flutter or skipped beat that passes within seconds or minutes, and you feel well afterwards.
• Palpitations after coffee, vaping, poor sleep or exercise that settle with rest.
• See a doctor if they continue despite cutting down triggers, or if they worry you.

If fainting or dizziness is the main problem, see our guide to fainting and dizziness: when to go to the ER, and for the signs you should never ignore, read heart attack warning signs.

Can vaping and nicotine cause heart palpitations?

Yes. Most vapes contain nicotine, a stimulant that temporarily raises your heart rate and blood pressure. With high-strength liquids or devices you puff on all day, nicotine can build up and some people notice a racing heart or extra beats. Cutting down the number of puffs or the strength often helps, and if you want to quit, ask a doctor or pharmacist for support. But heart pain or chest tightness after vaping is not something to wait out: call 911. For lung symptoms, see our guide to vaping lung warning signs.

Palpitations after coffee or an energy drink?

Caffeine is one of the most common triggers. The US FDA says up to about 400 mg a day — roughly four or five cups of coffee — is generally safe for healthy adults, but sensitivity varies, some energy drinks pack a lot into one can, and strong Arabic or Turkish coffee can be more potent than you think. If you notice palpitations, stop caffeine for the rest of the day and drink water. For warning signs of having too much, see energy drink and caffeine overdose symptoms.

Palpitations at night, or a racing heart from anxiety?

Many people notice their heartbeat more at night because the room is quiet and the body is still, especially lying on the left side. Late coffee, alcohol, a heavy dinner and worry can make it worse. Panic attacks cause a pounding heart with fast breathing, sweating, shaking and intense fear, usually easing within minutes. But you can't safely tell panic from a heart problem at home, so if it's a first episode or comes with chest pain, call 911. Our guide panic attack or heart attack? explains the differences.

How can you ease palpitations at home?

If palpitations aren't caused by a health condition, avoiding triggers often helps:

• Cut down caffeine and nicotine. Coffee, tea, energy drinks, cola, vapes and cigarettes, especially later in the day.
• Get enough sleep. Poor sleep is one of the most common triggers.
• Drink water. Dehydration, especially in summer, after exercise or when ill, can speed up your heart.
• Limit alcohol and avoid recreational drugs.
• Calm stress: breathe slowly — in for four seconds, out for six — and try walking or relaxation exercises.
• Keep a diary: when it happened, how long it lasted, what you were doing and drinking. This helps a doctor a lot.

What happens when you come to Emergency Plus?

At the emergency department at Emergency Plus in Dabouq, emergency physicians are on site 24/7 and you can walk in without an appointment. The doctor asks about your episodes — how they feel, how long they last and what sets them off — your medicines, caffeine and nicotine use and family history, then checks your pulse and blood pressure and examines you. They may request blood tests from the on-site laboratory, for example to look for anaemia, thyroid problems or salt imbalances, and will advise whether you need follow-up with a heart specialist. Our team speaks Arabic and English.
