Key Takeaways
- Panic attacks can trigger sudden and severe physical symptoms, such as chest tightness, a rapid heartbeat, sweating, and difficulty breathing
- Symptoms generally reach their maximum intensity within minutes and may last from several minutes to over an hour
- Panic attack symptoms can closely mimic a heart attack; a first episode should always be medically evaluated
- "Anxiety attack" is an informal term, not a clinical diagnosis like "panic attack"
- Treatment options include cognitive-behavioural therapy (CBT) and medications
- During an attack, staying still, breathing slowly, and reminding yourself it will pass can help
A panic attack can occur suddenly, bringing intense fear along with physical symptoms like chest tightness, a racing heart, and difficulty breathing[1]. These symptoms often feel so severe that many people believe they are having a heart attack[2]. Although “panic attack” and “anxiety attack” are often used interchangeably, only “panic attack” is a formally recognised clinical term[1]. This article provides general education about panic attack symptoms, causes, and management. It is not a substitute for emergency evaluation of chest symptoms or a mental health diagnosis.
When panic attack symptoms could be a medical emergency
If you experience chest pain, difficulty breathing, or other severe physical symptoms for the first time, seek immediate medical attention[1]. As these symptoms can resemble those of a heart attack, a healthcare professional must assess them to determine the underlying cause[2]. Although panic attacks are generally not life-threatening, it is crucial to rule out cardiac or other medical conditions, particularly during a first episode[1].
What is a panic attack?
A panic attack is an abrupt onset of overwhelming fear, often accompanied by intense physical symptoms. These episodes occur unexpectedly, often without any obvious trigger or danger[3].
Panic attacks may happen at any moment, including while a person is asleep[1]. Nocturnal panic attacks wake a person from sleep with the same symptoms as daytime attacks, often without any obvious trigger[4]. Understanding the symptoms and processes involved in a panic attack can help ease fear and support better management, even though the experience can be distressing.
Panic attack symptoms
A panic attack often involves a sudden wave of severe emotional and physical symptoms that intensify quickly and generally peak within minutes. The following table outlines common panic attack symptoms[5]:
Symptom Category | Specific Symptoms |
|---|---|
Cardiovascular | Racing heartbeat, pounding heart, chest pain |
Respiratory | Shortness of breath, choking sensation |
Neurological | Dizziness, feeling faint, numbness or pins and needles |
Gastrointestinal | Nausea, churning stomach |
Temperature-related | Sweating, hot flushes, chills |
Muscular | Trembling, shaky limbs |
Psychological | Fear of dying, feeling disconnected from your body |
These symptoms can be intense but typically resolve as the attack subsides[1].
Panic attack vs anxiety attack: What's the real difference?
While "panic attack" is a recognised clinical term with specific diagnostic criteria, "anxiety attack" is not a formal diagnosis used in mental health services. However, people commonly use both terms to describe intense episodes of anxiety. The key difference between panic attacks and anxiety attacks lies in how symptoms develop[6]:
- Panic attacks tend to come on very suddenly and peak within minutes, often without warning
- Anxiety usually builds gradually over time in response to perceived stressors
Panic attacks can occur unexpectedly even when a person feels calm, whereas anxiety typically follows a period of worry or stress[6]. Both can cause similar physical symptoms, but the sudden, intense nature of panic attacks distinguishes them from general anxiety.

Panic attack vs heart attack: how to tell the difference
Here are the differences between panic attacks and heart attacks[7]:
Feature | Panic Attack | Heart Attack |
|---|---|---|
Chest pain type | Sharp or stabbing, localised to middle of chest | Pressure or squeezing sensation |
Pain radiation | Usually stays in the chest area | May spread to arm, jaw, or shoulder blades |
Onset | Sudden, peaks within minutes | Often builds gradually |
Duration | Typically fades within a few minutes | Persists and may intensify without treatment |
Despite these differences, it is important to seek urgent medical assessment for chest pain, especially if you have never experienced it before or the symptoms are severe.
What causes panic attacks?
The precise cause of panic attacks is not yet fully understood, although researchers suggest that several factors may play a role[2]:
- Genetics: Panic disorder may have a hereditary component and can run in families
- Brain biology and chemistry: Variations in brain processes and chemical activity involved in regulating fear and anxiety may contribute to panic attacks
- Major life stress: Significant stressors can trigger the onset of panic attacks
- Traumatic experiences: Exposure to traumatic events, especially during early childhood, may increase a person’s susceptibility to developing panic disorder
Panic disorder is more prevalent among women and commonly begins in the late teenage years or early adulthood[2].
How are panic attacks treated?
Treatment for panic attacks typically involves talking therapies, medication, or both, depending on your symptoms[5]. Recent international guidelines recommend evidence-based interventions for anxiety disorders, including panic disorder[8].
Talking therapies
Cognitive-behavioural therapy (CBT) is a common treatment for panic disorder. CBT helps you identify and change negative thought patterns and reactions that contribute to panic attacks[2].
Medications
Your doctor may prescribe medications, including antidepressants (such as SSRIs and SNRIs) or anti-anxiety medicine[2]. These medications may be used to reduce the frequency and severity of panic attacks.
Treatment options should be selected by a qualified healthcare professional after assessing your symptoms and reviewing your medical history.
What to do during a panic attack
When you feel a panic attack coming on, these strategies may help[1],[5]:
- Stay where you are: If possible, remain in place rather than trying to flee
- Breathe slowly and deeply: Focus on slow, controlled breathing
- Focus on something peaceful: Concentrate on positive, calming images
- Remember it is not dangerous: While frightening, panic attacks are not life-threatening
Practising these techniques regularly can help you feel more prepared when an attack occurs.

Conclusion
Panic attacks can be frightening, but understanding their symptoms and knowing what to do can help you manage them effectively. Remember that panic attacks, while intense, are not life-threatening and typically pass within a few minutes. If you experience symptoms for the first time or are unsure whether you are having a panic attack or heart attack, seek immediate medical evaluation. With proper treatment, including therapy and medication, many people successfully manage panic disorder and reduce the frequency of attacks.
FAQs
Can panic attacks cause real physical harm, like a heart problem?
Panic attacks are not life-threatening and do not cause direct physical damage to your heart. While the symptoms feel intense, they typically resolve completely. However, chronic stress from repeated attacks may affect overall cardiovascular health over time.
How long does a typical panic attack last?
Most panic attacks last from a few minutes to an hour. The most intense symptoms usually peak within the first few minutes. Some lingering symptoms may persist longer, but the acute phase is generally brief.
Is it normal to have a panic attack for the first time as an adult with no history of anxiety?
Yes, this is common. Panic disorder typically emerges during the late teenage years or early adulthood. A first panic attack can occur suddenly without any prior anxiety history, often triggered by stress or occurring seemingly out of nowhere.
Can panic attacks happen during sleep?
Yes, nocturnal panic attacks can wake you from sleep with the same symptoms as daytime attacks. You may suddenly awaken feeling intense fear, rapid heartbeat, and other panic symptoms without any obvious trigger.
Should I go to the ER if I think I'm having a panic attack?
If it is your first episode or symptoms resemble a heart attack (chest pain, difficulty breathing), seek emergency evaluation. Only medical professionals can rule out cardiac causes. When in doubt, it is always safer to get checked.
Is an "anxiety attack" just a less severe version of a panic attack?
Not exactly. "Anxiety attack" is an informal term without a clinical definition, while "panic attack" is a recognised clinical term with specific criteria. People use "anxiety attack" loosely to describe various anxiety experiences.
