Panic Disorder: When Your Body Says Heart Attack But It's Not

Your heart suddenly starts racing. Your chest tightens. Your hands tingle. You feel like you cannot get a full breath. A wave of dread tells you something is very, very wrong — maybe you are having a heart attack. Maybe you are losing your mind. Then, ten or fifteen minutes later, it passes.

If that has happened to you more than once, and you find yourself dreading the next one, please keep reading. Panic disorder symptoms are real, they are treatable, and you are not alone in this.

This guide walks through what panic disorder actually is, why it feels so physical, what evidence-based treatment looks like — including a technique called interoceptive exposure that can genuinely change the pattern — and what care options Georgia residents have.

A quick caveat before we go deeper: anything in this article is educational. A licensed clinician makes the actual diagnosis. If you have unexplained chest pain, get a medical evaluation first to rule out cardiac causes — then a mental health workup makes sense as a next step.

What Is Panic Disorder?#

Panic disorder is a clinical anxiety condition defined by two things: recurrent unexpected panic attacks and, for at least one month after, persistent worry about having another one or significant behavior changes to avoid them (NIMH, 2024).

A single panic attack is not the disorder. Many people have one panic attack in their lifetime, usually under acute stress, and never have another. Panic disorder is what happens when the attacks keep coming back — and when the fear of the next attack begins to organize your life.

It affects about 2 to 3 percent of U.S. adults in any given year, with women diagnosed roughly twice as often as men. Typical onset is late adolescence to early adulthood, though it can begin at any age.

Quick answer: Panic disorder is recurrent unexpected panic attacks plus a month or more of worry about future attacks or avoidance behavior. It is highly treatable.

Signs and Symptoms of Panic Disorder#

During a panic attack, the body fires a full sympathetic nervous system surge. The symptoms come fast and can include:

• Palpitations or a pounding heart
• Sweating, sometimes drenching
• Trembling or shaking
• Sensations of shortness of breath or smothering
• Feelings of choking
• Chest pain or tightness
• Nausea or stomach distress
• Dizziness, lightheadedness, or feeling faint
• Chills or heat sensations
• Numbness or tingling (paresthesias) in hands, feet, or face
• A sense of unreality (derealization) or being detached from yourself (depersonalization)
• Fear of losing control or "going crazy"
• Fear of dying

Between attacks, the hallmark of the disorder is what clinicians call anticipatory anxiety — a low-grade, persistent dread of when the next attack will hit. Many people start subtly reorganizing their lives: avoiding the grocery store where the last attack happened, sitting near exits in restaurants, declining to drive on highways, skipping the meeting where they cannot easily leave the room.

That avoidance pattern is how panic disorder slowly shrinks your world.

Why It Feels Like a Heart Attack#

This is one of the most important things to understand about panic. Your body is not malfunctioning — it is doing exactly what it evolved to do. The threat detection system fires the survival response: adrenaline, faster heart rate, more oxygen, narrowed focus. The problem is that the trigger is no longer a saber-tooth tiger. The trigger is often the body's own physical sensations.

A slightly elevated heart rate after climbing stairs — perfectly normal — gets misread by the brain as the start of an attack. The misreading itself triggers more adrenaline. Within seconds, you are in a full panic response that mimics a cardiac event (Cleveland Clinic, 2024).

This is why panic disorder is a leading cause of emergency room visits for non-cardiac chest pain. People walk in convinced they are dying. The EKG comes back clean. The blood work is normal. They are sent home with paperwork and no explanation, often more frightened than before.

A few common misreadings worth naming:

• "I am having a heart attack." Panic mimics cardiac symptoms, but workup is negative. Once medically cleared, panic disorder is the appropriate next consideration.
• "I am going crazy." Panic attacks do not cause psychosis. The feeling of unreality is a symptom of the panic, not a sign of losing your mind.
• "I will never be able to leave the house." Untreated panic does drive avoidance, sometimes into agoraphobia. But with treatment, the trajectory reverses.

Evidence-Based Treatments That Actually Work#

The good news — and we say this with measured optimism, not promises — is that panic disorder is one of the most treatable anxiety conditions when the right approach is used.

Cognitive Behavioral Therapy with Interoceptive Exposure

First-line treatment is Cognitive Behavioral Therapy (CBT) with interoceptive exposure, a technique developed specifically for panic (APA, 2024; Craske et al., NCBI, 2009).

Interoceptive exposure is the deliberate, gradual reproduction of the physical sensations of panic in a controlled setting. Examples include:

• Spinning in a chair to induce dizziness
• Breathing through a thin straw to mimic shortness of breath
• Running in place to elevate heart rate
• Hyperventilating briefly with your therapist present

This sounds counterintuitive — why would you deliberately bring on the very sensations you are terrified of? Here is why it works: your brain has learned that these physical feelings are dangerous. Repeatedly experiencing them in a safe context, with no catastrophe following, slowly retrains the threat detection system. The sensations become uncomfortable instead of life-threatening.

Most CBT-for-panic protocols run 12 to 15 sessions. Cognitive components address the catastrophic predictions ("I will die if my heart rate gets that high"). Behavioral components include the interoceptive work plus in-vivo exposure to feared situations.

Medication

SSRIs are FDA-approved for panic disorder and often a meaningful addition. Common options include sertraline, paroxetine, fluoxetine, and escitalopram. SNRIs like venlafaxine also have evidence.

Benzodiazepines (lorazepam, alprazolam, clonazepam) reduce acute symptoms quickly but have limited long-term role due to dependence risk, and they can blunt the learning that exposure therapy depends on. Most clinicians use them sparingly, if at all.

Mindfulness-based approaches and acceptance-based therapies show good evidence as adjuncts.

What Therapy for Panic Disorder Looks Like at CHC#

At Coping & Healing Counseling, our team of fifteen-plus licensed Georgia therapists provides panic disorder care via secure video sessions across all 159 counties. Here is what that typically looks like:

1. Intake assessment — usually 50 to 60 minutes. We map your panic history, current frequency, triggers, avoidance patterns, and rule out other conditions that can look similar (cardiac issues if not yet evaluated, thyroid dysfunction, substance-induced anxiety).

2. Psychoeducation — the first one or two sessions cover what panic is, why it feels physical, and what the treatment plan will look like. Knowing the mechanism alone reduces fear for many people.

3. Skills work — diaphragmatic breathing, cognitive restructuring for catastrophic thoughts, grounding techniques.

4. Interoceptive exposure — graduated, collaborative, and always at your pace. We never push past what you can tolerate.

5. In-vivo exposure — practicing the situations you have been avoiding, often supported by the fact that you are in your own environment for the telehealth session.

6. Medication coordination — if SSRI is on the table, we coordinate with your primary care provider or psychiatrist.

Most commercial insurance plans (Aetna, BCBS, UHC, Cigna, Humana) cover sessions at $10 to $40 per visit. Medicaid is $0 copay.

What You Can Do This Week#

• Get medically cleared first if you have not yet had unexplained chest pain evaluated by a physician.
• Track your attacks — date, duration, what you were doing, what you noticed first. Patterns become visible quickly.
• Limit caffeine and stimulants while you assess — they amplify the physical sensations panic feeds on.
• Practice slow diaphragmatic breathing — 4 seconds in, 6 to 8 seconds out, for 5 minutes daily. This is not a cure, but it builds a skill your body can reach for.
• Reach out to a therapist trained in CBT for panic. The longer you wait, the more avoidance entrenches.

Frequently Asked Questions#

How long does a panic attack last?

Most panic attacks peak within 10 minutes and resolve within 20 to 30 minutes, even though they can feel timeless in the moment. The body cannot sustain the surge indefinitely. After the peak, the physical symptoms gradually fade, often leaving exhaustion or shakiness.

Can panic disorder go away on its own?

Untreated panic disorder often becomes chronic and frequently develops into agoraphobia, where the person avoids places they associate with past attacks. Early evidence-based treatment with CBT — especially interoceptive exposure — significantly reduces frequency and intensity within 12 to 15 sessions.

Is panic disorder the same as a heart attack?

No. Panic attacks mimic cardiac symptoms — chest tightness, shortness of breath, racing heart — but a cardiac workup is negative. That said, any unexplained chest pain warrants medical evaluation first. Once cardiac causes are ruled out, panic disorder becomes the appropriate diagnostic consideration.

What is interoceptive exposure?

Interoceptive exposure is a CBT technique that deliberately reproduces the physical sensations of panic in a safe, graduated way — spinning to induce dizziness, breathing through a straw, or running in place. Repeated exposure teaches the brain that these sensations are uncomfortable, not dangerous.

Can panic disorder be treated with telehealth?

Yes — telehealth is often ideal for panic disorder because sessions take place in the environments where attacks happen, supporting in-vivo exposure work. Coping & Healing Counseling provides HIPAA-compliant video therapy across all 159 Georgia counties, in-network with most major plans.

Do I need medication for panic disorder?

Medication is not required, but SSRIs (sertraline, escitalopram, paroxetine, fluoxetine) are FDA-approved options that many people find helpful alongside therapy. The decision is collaborative — between you, your prescriber, and your therapist — based on severity and personal preference.
