Alcohol withdrawal heart symptoms can develop when someone who drinks heavily or regularly suddenly stops drinking or sharply reduces their alcohol intake. Common symptoms include a racing heartbeat, pounding in the chest, increased blood pressure, sweating, shakiness and anxiety.
Although some heart-related symptoms occur during mild withdrawal, alcohol withdrawal can become life-threatening. Chest pain, fainting, breathing difficulty or an irregular heartbeat should never be ignored. A person at risk of withdrawal should speak with a healthcare professional before attempting to stop drinking without medical support.
How Alcohol Withdrawal Affects The Heart?
Alcohol slows activity in the central nervous system. When a person drinks heavily over an extended period, the brain gradually adjusts to the constant presence of alcohol.
If alcohol is suddenly removed, the nervous system can become unusually active. This overactivity affects the body’s automatic functions, including heart rate, blood pressure, breathing, sweating and body temperature.
As a result, the heart may beat faster or harder than normal. Anxiety, dehydration, vomiting, poor sleep and changes in electrolyte levels can place additional strain on the cardiovascular system.
The severity of withdrawal varies widely. Some people experience mild shaking and anxiety, while others develop seizures, dangerous heart rhythm changes or delirium tremens.
Common Alcohol Withdrawal Heart Symptoms
Rapid Heart Rate
A rapid heart rate, also known as tachycardia, is one of the most common alcohol withdrawal heart symptoms. A person might notice that their pulse feels faster than usual, even while resting.
A racing heart often occurs with sweating, tremors, restlessness, nausea or anxiety. The National Institute on Alcohol Abuse and Alcoholism lists a racing heart among the recognized symptoms that can develop as alcohol’s effects wear off.
A consistently fast heart rate requires medical assessment, particularly when it occurs after heavy or prolonged alcohol use.
Heart Palpitations
Palpitations are sensations of feeling the heart beat. They may feel like:
- Pounding in the chest
- Fluttering
- Skipped beats
- A forceful heartbeat
- A rapid or uneven pulse
Heart palpitation can result from nervous system overactivity, anxiety, dehydration or abnormal levels of potassium, magnesium and other electrolytes.
Not every heart palpitation indicates a dangerous heart condition. However, medical care is necessary when palpitations are persistent, irregular or accompanied by chest pain, dizziness, fainting or shortness of breath.
Increased Blood Pressure
Blood pressure can rise during alcohol withdrawal because the nervous system releases stress-related signals. This increase may occur with headache, sweating, agitation and a rapid pulse.
A temporary increase in blood pressure does not always cause noticeable symptoms. However, severe or sustained hypertension can be dangerous, especially for someone with heart disease, kidney disease or a history of stroke.
Blood pressure should be monitored by a healthcare professional during moderate or severe withdrawal.
Irregular Heartbeat
Alcohol withdrawal can sometimes cause an abnormal heart rhythm. A person might experience skipped beats, fluttering or an unpredictable pulse.
MedlinePlus notes that an examination during withdrawal can reveal abnormal heart rhythms. Irregular heartbeats are also listed among the symptoms that require emergency medical attention.
An irregular heartbeat should not be dismissed as anxiety. An electrocardiogram, commonly called an ECG or EKG, may be needed to determine what is happening.
Chest Pain Or Tightness
Chest discomfort can develop during severe withdrawal, but it should not be considered harmless or expected. Chest pain could indicate an abnormal heart rhythm, severe blood pressure elevation, heart muscle strain or another medical emergency.
It can also have causes unrelated to withdrawal, including acid reflux, panic symptoms, lung problems or a heart attack. It is not possible to identify the cause safely based on symptoms alone.
Call emergency services for chest pressure, squeezing or pain that spreads to the arm, jaw, shoulder or back. Immediate help is also necessary when chest pain occurs with sweating, nausea, faintness or breathing difficulty.
Dizziness And Feeling Faint
Withdrawal can cause dizziness because of dehydration, vomiting, blood pressure changes, low blood sugar or an abnormal heart rhythm.
Feeling faint during withdrawal is concerning. Fainting can lead to injuries and may indicate that the heart is not pumping blood effectively. A person who loses consciousness requires urgent medical evaluation.
Shortness Of Breath
Anxiety and panic can make someone feel unable to take a full breath. However, shortness of breath can also indicate a heart rhythm problem, cardiovascular strain or another serious condition.
Breathing difficulty accompanied by chest pain, blue or pale skin, confusion, severe weakness or an irregular pulse is an emergency.
When Do Heart Symptoms Begin?
Alcohol withdrawal symptoms commonly begin within approximately eight hours after the last drink, although they may appear later. Symptoms often become strongest within 24 to 72 hours. Some problems, such as sleep disturbance, mood changes and fatigue, can continue much longer.
A general withdrawal timeline may look like this:
- Within 6 to 12 Hours
Early symptoms can include anxiety, trembling, sweating, headache, nausea, trouble sleeping and a faster heartbeat.
- Between 12 and 48 Hours
Symptoms may become more intense. Blood pressure and pulse can rise, and seizures can occur during this period.
- Between 48 and 96 Hours
People at risk can develop delirium tremens, a severe form of alcohol withdrawal. It may cause extreme confusion, agitation, fever, hallucinations, rapid heart rate, irregular heartbeat and seizures. Delirium tremens is a medical emergency.
A person should not assume they are safe simply because the first several hours were manageable. Severe complications can develop after earlier symptoms appear mild.
Who Is At Greater Risk Of Severe Withdrawal?
Severe withdrawal is more likely among people who:
- Have been drinking heavily or regularly for a prolonged period
- Have previously experienced withdrawal seizures or delirium tremens
- Have had several previous withdrawal episodes
- Have heart disease or another significant medical condition
- Are dehydrated, malnourished or physically unwell
- Are also using sedatives or other substances
- Have severe symptoms when alcohol begins wearing off
Someone with a history of severe withdrawal should not attempt to detox alone. A clinician can decide whether outpatient monitoring, a detoxification facility or hospital treatment is safest.
When Are Alcohol Withdrawal Heart Symptoms An Emergency?
Call emergency services or go to the nearest emergency department for:
- Chest pain, pressure or squeezing
- A clearly irregular heartbeat
- Fainting or inability to remain awake
- Severe shortness of breath
- A seizure
- Hallucinations
- Severe confusion
- High fever
- Extreme agitation
- Blue, grey or unusually pale skin
- Sudden weakness on one side of the body
- Symptoms that rapidly become worse
Alcohol withdrawal can progress quickly from uncomfortable symptoms to a life-threatening condition. MedlinePlus advises emergency care for seizures, fever, severe confusion, hallucinations or irregular heartbeats.
Do not leave a severely unwell person alone. Do not allow them to drive themselves to the hospital.
How Doctors Evaluate Heart Symptoms During Withdrawal?
A healthcare professional may ask about the person’s drinking pattern, the time of their last drink, previous withdrawal episodes, current medications and existing medical conditions.
The evaluation may include:
- Heart rate and blood pressure monitoring
- An ECG to examine the heart rhythm
- Blood tests
- Blood sugar testing
- Electrolyte testing
- Liver and kidney function tests
- Assessment for dehydration
- Evaluation for infection, injury or other substance use
These tests help determine whether symptoms come from withdrawal, a separate heart condition or a combination of problems.
How Alcohol Withdrawal Is Treated?
Treatment depends on symptom severity, medical history and the risk of complications.
Mild withdrawal can sometimes be managed through a structured outpatient program. The person may need daily medical visits and a responsible adult to remain with them.
Moderate or severe withdrawal usually requires treatment in a hospital or specialized facility. Care can include medication to control nervous system overactivity, fluids, electrolyte correction and close monitoring of heart rate, blood pressure, breathing and temperature.
Medications used during detoxification must be selected and monitored by a qualified healthcare professional. Combining alcohol with sedatives or taking someone else’s medication can cause dangerous breathing problems, excessive sedation or overdose.
Can Alcohol Withdrawal Be Managed At Home?
Home withdrawal is not safe for everyone. The absence of serious symptoms during a previous attempt does not guarantee that the next withdrawal will be mild.
Before stopping, a person who drinks heavily every day should contact a doctor, addiction treatment service or urgent care provider. A medical professional can assess the risk and recommend the appropriate treatment setting.
Medical detoxification does more than improve comfort. It helps prevent delirium tremens, seizures, and serious cardiovascular complications. NIAAA advises people who have been drinking heavily for a prolonged period to seek medical help when planning to stop.
Alcohol Withdrawal Versus A Hangover
A hangover usually occurs after a single episode of drinking and can cause thirst, headache, nausea, fatigue, anxiety, sweating and increased blood pressure.
Withdrawal develops when a person’s body has become physically dependent on alcohol and alcohol intake stops or drops sharply. It is more likely to cause significant tremors, a racing heart, severe agitation, hallucinations or seizures.
Because symptoms can overlap, people with frequent or heavy alcohol use should not assume that heart palpitations and shaking are simply a hangover.
Final Verdict
Alcohol withdrawal heart symptoms commonly include a rapid heartbeat, pounding heart, increased blood pressure and palpitations. More serious cases can involve chest pain, fainting, abnormal heart rhythms and breathing difficulty.
Withdrawal can become dangerous without warning. Anyone who drinks heavily or has experienced withdrawal before should seek medical guidance before stopping. Chest pain, seizures, hallucinations, severe confusion or an irregular heartbeat require emergency treatment.
