Feeling your heart race, pound, flutter, or skip beats can be frightening, especially after cutting back on alcohol or stopping suddenly. Alcohol withdrawal and heart palpitations can occur together because withdrawal affects the nervous system and can increase heart rate, blood pressure, sweating, anxiety, and shakiness. NIAAA lists a racing heart among possible alcohol withdrawal symptoms, while MedlinePlus also notes that rapid heart rate and abnormal heart rhythms can occur.
Not every palpitation means there is a dangerous heart problem, but alcohol withdrawal can become serious quickly. Anyone who has been drinking heavily or regularly should take new heart symptoms seriously rather than trying to manage withdrawal alone.
Why Can Alcohol Withdrawal Cause Palpitations?
Alcohol affects the brain and nervous system. With repeated heavy drinking, the body adapts to alcohol’s depressant effects.
- Nervous Activation
- Rising Pulse
- Blood Pressure
- Stress Hormones
- Increased Anxiety
- Body Tremors
When alcohol is suddenly removed, the nervous system can become overactive. This may cause shaking, sweating, anxiety, insomnia, and a racing or pounding heartbeat. NIAAA notes that alcohol withdrawal may involve elevated pulse and blood pressure as well as nausea, sweating, seizures, and other symptoms.
What Do Heart Palpitations Feel Like?
Palpitations can feel different from person to person.
- Racing Heart
- Pounding Heart
- Skipped Beats
- Fluttering Feeling
- Chest Thumping
- Irregular Rhythm
Some people notice symptoms mainly while resting or trying to sleep. Others may feel their heart beating strongly during anxiety, sweating, or shaking.
Withdrawal can cause a rapid pulse, but other problems may also produce palpitations. Dehydration, electrolyte changes, medications, stimulant use, anxiety, and an underlying heart condition can all contribute.
When Does Alcohol Withdrawal Begin?
Withdrawal symptoms can start surprisingly quickly.
- Early Symptoms
- First Hours
- Peak Period
- Changing Severity
- Delayed Symptoms
- Ongoing Monitoring
MedlinePlus reports that alcohol withdrawal symptoms often begin within about eight hours after the last drink, though they can appear later. Symptoms commonly peak between 24 and 72 hours.
The exact timeline depends on how much and how often someone drinks, previous withdrawal experiences, overall health, and other substances or medications being used.
Other Alcohol Withdrawal Symptoms
Heart palpitations are rarely the only symptom.
- Hand Tremors
- Heavy Sweating
- Nausea
- Poor Sleep
- Severe Anxiety
- Headaches
People may also experience irritability, restlessness, loss of appetite, mood changes, or difficulty concentrating. More serious withdrawal can include hallucinations, seizures, fever, or severe confusion. MedlinePlus describes delirium tremens as a severe form of withdrawal that may involve agitation, fever, hallucinations, seizures, and sudden confusion.
When Are Palpitations an Emergency?
Some heart symptoms should never be ignored.
- Chest Pain
- Severe Dizziness
- Fainting
- Breathing Trouble
- Irregular Heartbeat
- Severe Confusion
MedlinePlus advises emergency evaluation for alcohol withdrawal accompanied by seizures, fever, severe confusion, hallucinations, or irregular heartbeats. Chest pressure, fainting, significant shortness of breath, or severe weakness also warrant urgent assessment because they can have causes unrelated to withdrawal.
Why Stopping Alcohol Suddenly Can Be Risky
People sometimes assume quitting immediately is always the safest choice, but sudden withdrawal after prolonged heavy drinking can be dangerous.
- Seizure Risk
- Heart Changes
- Severe Withdrawal
- Delirium Tremens
- Blood Pressure
- Medical Complications
NIAAA warns that withdrawal after chronic heavy drinking can be potentially life-threatening and that some people need medical monitoring or detoxification.
The safest approach depends on drinking history, past withdrawal symptoms, medical conditions, medications, and other factors.
How Doctors Evaluate Heart Palpitations
Medical evaluation helps determine whether symptoms are from withdrawal or another problem.
- Heart Rate
- Blood Pressure
- Medical History
- Blood Tests
- ECG Testing
- Symptom Review
MedlinePlus notes that clinicians may check for rapid or abnormal heart rhythms and may perform an electrocardiogram, along with blood or urine testing when appropriate. Doctors may also look for dehydration, electrolyte abnormalities, medication effects, or existing heart conditions. Knowing how much alcohol was being consumed and when the last drink occurred can help clinicians assess withdrawal risk more accurately.
Treatment Depends on Severity
Alcohol withdrawal treatment is not the same for everyone.
- Medical Monitoring
- Withdrawal Medication
- Fluid Support
- Symptom Control
- Inpatient Care
- Outpatient Care
ASAM states that withdrawal management may take place in outpatient or inpatient settings depending on the person’s risk and clinical needs. It also emphasizes that withdrawal management alone is not treatment for alcohol use disorder. Some people can be managed with close outpatient supervision, while those at risk for severe withdrawal may require 24-hour medical care.
Recovery Should Continue After Withdrawal
Getting through withdrawal is only one part of recovery.
- Medical Follow-Up
- Counseling
- Medication Options
- Peer Support
- Trigger Planning
- Long-Term Care
Treatment for alcohol use disorder may include behavioral therapy, medication, support programs, or a combination of approaches. NIAAA notes that evidence-based treatment is available in outpatient, residential, and inpatient settings depending on individual needs.
Final Thought
Alcohol withdrawal and heart palpitations can occur together because suddenly reducing alcohol after regular heavy use may cause the nervous system to become overactive. A racing or pounding heart may be part of withdrawal, but it can also signal a more serious problem. Do not ignore severe or persistent symptoms, especially if they occur with chest pain, fainting, breathing problems, seizures, hallucinations, confusion, or an irregular heartbeat. If you may be physically dependent on alcohol, seek medical guidance before stopping suddenly and get urgent help if symptoms become severe.
