Holiday Heart Syndrome

Overview

Holiday Heart Syndrome is the name doctors use when a person's heartbeat becomes irregular after drinking a lot of alcohol in a short time, often during holidays, parties or weekends. The most common pattern is a fast, fluttering or racing heart, sometimes caused by a rhythm problem called atrial fibrillation (AF) — a condition where the upper chambers of the heart quiver instead of beating steadily. It is not a disease of the heart muscle itself. It is a temporary reaction to a trigger, and for most people it settles down within a day or two once the trigger is removed.

Yes, it is fairly common. Emergency departments and family doctors often see a rise in people with a racing or irregular heartbeat during holiday periods and at weekends. It can happen to people with completely healthy hearts, and it becomes more common as people get older.

It can affect anyone, but it is seen most often in adults who drink heavily now and then, especially middle-aged and older adults. People who already have heart disease, high blood pressure, sleep apnoea (a breathing problem during sleep) or an overactive thyroid are more likely to be affected. It is rare in children and teenagers.

Symptoms

Common symptoms

• A fluttering, pounding or racing feeling in the chest (palpitations)
• Feeling that your heart has skipped a beat or is beating unevenly
• A pulse that feels fast and irregular when you check it
• Feeling light-headed, dizzy or faint
• Shortness of breath, especially with mild activity
• Feeling unusually tired or washed out
• Mild chest discomfort or a sense of unease
• Feeling anxious, which can itself make the heartbeat feel worse

Symptoms in children

• Holiday Heart Syndrome is rare in children because it is usually linked to alcohol.
• A child who says their heart is racing, fluttering or 'beating funny' should still be checked by a doctor.
• In children, palpitations are more often caused by fever, dehydration, anxiety, caffeine in energy drinks, or an inherited heart rhythm condition.
• Seek urgent care if a child faints, turns pale or blue, has chest pain, or cannot catch their breath.

Symptoms in older adults

• Older adults may notice less chest fluttering and more of a general feeling of weakness, tiredness or breathlessness.
• Dizziness and falls can be the first sign of an irregular heartbeat in this age group.
• Existing heart conditions, blood pressure medicines and dehydration from the heat or illness can make episodes more likely.
• Because the risk of stroke is higher with atrial fibrillation in older adults, any suspected irregular heartbeat should be checked promptly.

Causes

Main causes

• Drinking a large amount of alcohol in one session (binge drinking) — this is the classic trigger
• Caffeine from coffee, strong tea, cola or energy drinks
• Dehydration, especially when combined with alcohol, hot weather or exercise
• Large, heavy or very salty meals
• Poor sleep and long days of travel or partying
• Stress and excitement, which raise adrenaline levels
• Smoking, vaping or nicotine replacement in high doses
• Some over-the-counter cold and flu remedies, and some recreational drugs

Risk factors

• Existing heart disease, heart valve problems or a previous heart attack
• High blood pressure
• Sleep apnoea (loud snoring with pauses in breathing during sleep)
• An overactive thyroid gland
• Low levels of potassium or magnesium in the blood, which can follow vomiting, diarrhoea or heavy drinking
• Being over 50
• A family history of heart rhythm problems
• Diabetes, obesity and long-term heavy alcohol use
• Taking several medicines that can affect heart rhythm — ask your pharmacist to check

When to see a doctor

See a doctor urgently if:

• You have chest pain, faint or nearly faint, or struggle to breathe — call your local emergency number right away
• Your heart is racing or irregular and has not settled after several minutes of sitting quietly
• You have repeated episodes in the same day or over a few days
• You feel very dizzy, sweaty or unwell alongside a racing heartbeat

Book a routine appointment if:

• You have had one or more episodes of a fluttering or racing heart, even if they settled
• You want to talk about your alcohol intake and how it affects your heart
• You have noticed your pulse feels irregular when you check it at rest
• You have a history of heart problems and want advice on safe limits during holidays

Diagnosis

A doctor will start by asking about what happened: when the racing started, how long it lasted, what you had been drinking or eating, how much sleep you had, and whether you have had it before. They will examine you, check your pulse and blood pressure, and usually do a heart tracing called an ECG (a painless test that records the heart's electrical signals). Because the rhythm may be normal again by the time you are seen, the doctor may ask you to wear a small monitor at home to catch an episode.

Tests that may be done

• ECG (electrocardiogram) — a quick, painless recording of your heartbeat
• Blood tests to check potassium, magnesium, kidney function, thyroid and to look for signs of long-term alcohol use
• A heart monitor worn for 24 hours or longer, or a small patch or smartwatch-style recorder, to catch an irregular rhythm
• Echocardiogram — an ultrasound scan of the heart to check its structure and valves
• Chest X-ray if there is breathlessness or a suspected chest problem
• A sleep apnoea assessment if you snore heavily or feel exhausted during the day

What to expect at your appointment

Most people need only a conversation, an examination and an ECG. You may be asked to keep a simple diary of when symptoms happen and what you had been drinking or doing beforehand. If tests are normal, that is good news, but it does not mean the episode was imagined — it often means the rhythm had already settled. Your doctor will use your story, plus whatever tests they can, to decide whether anything else needs checking.

Treatment

For most people, treatment is simple: stop the trigger, rest, rehydrate and let the heart settle. If the irregular heartbeat does not settle, or if you are at higher risk of complications, your doctor may suggest medicines or a short hospital stay to bring the rhythm back to normal and to protect against stroke. The plan depends on your age, your other health conditions and what the heart tracing shows.

Self-care at home

• Stop drinking alcohol for at least a few days, and then keep to low levels or none at all
• Drink water steadily — aim for pale urine — especially after alcohol, in hot weather, or during travel
• Cut back on strong coffee, energy drinks and very large doses of caffeine
• Eat regular, balanced meals rather than one huge salty feast
• Protect your sleep — aim for a regular bedtime and avoid late-night heavy drinking
• Sit down, breathe slowly and rest if you feel your heart flutter; note the time and how long it lasts
• Learn to check your own pulse, and write down what you find
• Avoid smoking, vaping and recreational stimulants

Medical treatments

If the rhythm does not settle by itself, a doctor may use a controlled procedure to reset the heartbeat, done with monitoring in a hospital or clinic. Medicines may be offered to slow a fast heartbeat, keep the rhythm steady, or — when the rhythm problem is the type that raises stroke risk — to make the blood less likely to clot. Which of these is right for you depends on your heart tracing, your age and your other health conditions, and it is a decision to make together with your doctor. Never start, stop or change any medicine without speaking to your doctor or pharmacist first.

When is surgery considered?

Surgery is almost never needed for Holiday Heart Syndrome. Occasionally, if someone has repeated rhythm problems, a heart specialist may discuss a small procedure called ablation, which uses a thin tube to calm the area of the heart causing the irregular signals. This is only considered after full assessment and is not a routine treatment.

Living with this condition

Most people go back to normal life quickly. The useful work is noticing patterns: which situations, drinks, foods or levels of tiredness seem to set off your symptoms. A simple notebook or phone app can help. Keep a copy of your test results and tell any doctor you see that you have had an episode of an irregular heartbeat.

Lifestyle tips

• Keep alcohol within low levels, and have several alcohol-free days each week — some people find it easiest to avoid it altogether
• Stay hydrated, especially when travelling, in hot weather or after exercise
• Keep caffeine moderate and swap energy drinks for water
• Aim for a steady sleep routine
• Stay physically active — regular gentle to moderate exercise is good for the heart
• Manage stress with breathing exercises, walking or talking to someone
• Ask your pharmacist to review your medicines, including cold and flu remedies, for anything that could affect heart rhythm

Diet and exercise

Eat regular meals built around vegetables, fruit, wholegrains, beans, nuts and lean protein, and go easy on very salty processed foods. Avoid crash diets and heavy drinking on an empty stomach. Regular moderate activity — brisk walking, swimming, cycling — helps your heart and your mood; build up gradually if you have not been active for a while. If exercise reliably brings on palpitations, mention it to your doctor before pushing harder.

Mental health and emotional wellbeing

A racing or irregular heartbeat can be frightening, and it is very common to feel anxious afterwards or to start worrying about your heart during everyday activities. That anxiety can itself make your pulse feel faster. Talking to your doctor about what happened often helps a lot, because knowing your test results were normal is reassuring. If worry is affecting your sleep, work or mood, tell your doctor — support such as counselling is available and works well. If you ever feel overwhelmed or unsafe, contact your local mental health crisis service or emergency number straight away.

Prevention

Largely, yes. Because the most common trigger is a big burst of alcohol, cutting back is the single most effective step. Many people find that keeping to no more than a small amount, drinking slowly, alternating alcohol with water and eating properly reduces or stops episodes completely. Avoiding dehydration, huge salty meals, energy drinks and all-nighters during holidays also helps a great deal.

Screening programmes

There is no routine screening test for Holiday Heart Syndrome. However, if you have repeated episodes, your doctor may suggest checking your pulse regularly, or using a heart monitor for a longer period, to see whether you are having atrial fibrillation. If you have atrial fibrillation, regular blood pressure checks and a review of your stroke risk become part of your routine care.

Complications

If left untreated

• Episodes may become more frequent or last longer
• Some people go on to develop atrial fibrillation as an ongoing condition, which raises the risk of stroke
• Repeated fast heart rhythms can, over time, weaken the heart muscle
• Fainting or dizziness can lead to falls, especially in older adults
• Continuing heavy drinking can cause other health problems, including liver, nerve and blood pressure problems

Long-term outlook

The outlook is generally very good. Most people who have a single episode recover fully within a day or two, and their heart tracing returns to normal. The key is to take the warning seriously without panicking: reduce the triggers, get checked, and follow up if symptoms return. Many people never have another episode once they change their drinking and self-care habits, and those who do develop an ongoing rhythm problem can be supported with effective treatment.
