Panic Attack Symptoms: Why They Can Feel Like a Heart Attack

Panic attack symptoms can be intense enough to make a person fear they are dying. The National Institute of Mental Health explains that panic attacks often include physical symptoms that might feel like a heart attack, such as a rapid heart rate, chest pain, difficulty breathing, dizziness, sweating, trembling, nausea, or tingling sensations. Panic attacks themselves are not usually life-threatening, and the physical symptoms generally resolve with time. But that does not mean chest pain should be brushed off. NHS guidance is clear that chest pain that does not go away, spreads to the arm, neck, jaw, stomach, or back, or comes with sweating, nausea, or shortness of breath needs urgent medical attention because a heart attack is life-threatening.

What is a panic attack?

A panic attack is a sudden surge of intense fear, discomfort, or loss of control that can happen even when there is no clear danger or trigger. NIMH notes that not everyone who has a panic attack develops panic disorder.

An isolated attack can happen once or occasionally. Panic disorder is different. It involves recurrent, unexpected panic attacks plus ongoing worry about another attack or behavior changes aimed at avoiding one.

What do panic attack symptoms feel like?

Panic attack symptoms can vary from person to person, but common panic attack symptoms include:

• racing or pounding heart
• chest pain or tightness
• sweating or chills
• trembling or shaking
• difficulty breathing
• dizziness or weakness
• numbness or tingling
• stomach pain or nausea
• feelings of doom, death, or losing control

NIMH notes that a panic attack can last from a few minutes to an hour or sometimes longer.

Why can a panic attack feel like a heart attack?

The body systems involved overlap. Both experiences can include chest discomfort, sweating, shortness of breath, nausea, dizziness, and an intense sense that something is seriously wrong. That is why people often become terrified during a panic attack and may go to the emergency room believing they are having a heart attack.

NIMH explains that some people with panic disorder feel their heart pounding and assume they are having a heart attack, which can intensify the cycle of fear. The frightening interpretation can become part of the problem, not just the physical symptoms.

Panic attack versus heart attack

This table is only a rough guide. It is not a safe way to self-diagnose chest pain. If you think you could be having a heart attack, get urgent medical help.

When should someone seek urgent medical help?

NHS guidance advises urgent emergency care for chest pain that does not go away, feels tight or crushing, spreads to the arms, neck, or jaw, or comes with severe breathing difficulty, sweating, nausea, fainting, or pale, blue, or grey skin.

In practice, it is safer to treat possible heart attack symptoms as medical emergencies rather than assume they are panic. This matters especially for a first episode, symptoms that feel different than usual, symptoms that last, or symptoms in someone with cardiac risk factors.

If panic attacks are self-limiting, why do they cause so much disruption?

Because the aftermath can become its own problem. NIMH notes that many people with panic disorder worry about the possibility of another attack and may significantly change their lives to avoid having another one.

• avoiding public places or transport
• staying close to home or medical help
• scanning the body for every sensation
• interpreting normal changes in heartbeat or breathing as danger
• limiting work, social life, travel, or exercise

This is one reason panic can shrink a person's life even between attacks.

When does panic become panic disorder?

Panic disorder is not diagnosed from one frightening episode alone. NIMH explains that diagnosis usually involves recurrent, unexpected panic attacks plus at least 1 month of ongoing worry about more attacks, fear about what the attacks mean, or behavior changes to avoid future attacks.

That means the clinical issue is not only the attack itself. It is also the fear, interpretation, and avoidance pattern that follows.

What kinds of treatment can help?

NIMH states that panic disorder is commonly treated with psychotherapy, medication, or both. It also describes cognitive behavioral therapy as a research-supported treatment and a gold-standard psychotherapy for panic disorder.

CBT often helps people learn to interpret bodily sensations differently, reduce fear of the sensations themselves, and gradually face places or situations they have started avoiding. If avoidance around fear is becoming central, our article on fear versus anxiety may add context. If the broader pattern feels more like persistent worry and threat monitoring, our guide on normal anxiety versus anxiety disorder may also help.

When should someone seek mental health support?

• Attacks keep returning: the panic cycle is repeating instead of settling.
• You are worrying constantly about the next one: anticipatory anxiety is taking over.
• Your work, travel, exercise, or social life is shrinking: avoidance is starting to organize daily life.
• Body sensations are triggering repeated dread: normal sensations keep being read as danger.
• Reassurance and medical checks do not reduce the fear for long: the fear quickly comes back.

You can start with our anxiety assessment, browse psychologists on MindGood, or use the crisis and emergency help page if there may be immediate mental health risk.

The practical takeaway

Panic attack symptoms can be intense, frightening, and physically convincing. They can also be self-limiting. But panic attack symptoms should never be used as a reason to casually dismiss chest pain or severe breathing symptoms without medical judgment. The safest approach is to rule out urgent medical danger first, then address the panic cycle, anticipatory anxiety, and avoidance that may follow.
