Panic attack or heart attack? How to tell the difference

Q: How can I tell a panic attack from a heart attack?

There are typical differences — panic chest discomfort is often sharp and shifting and peaks within about 10 minutes, while heart-attack pain is often pressure or squeezing that radiates to the arm, jaw or back and can worsen with exertion. But these are not reliable enough to self-diagnose. If in doubt, treat it as a possible heart problem and seek emergency care.

Q: When should I call emergency services?

Call emergency services immediately if there is chest pressure or pain spreading to the arm, jaw, neck or back; shortness of breath with the pain; a cold sweat, nausea or vomiting; fainting; symptoms brought on by exertion; or if this is the first time and you are unsure. When in doubt, call.

Q: Can anxiety cause chest pain?

Yes. Anxiety and panic commonly cause chest tightness or pain from muscle tension and rapid breathing. It is real and harmless in itself — but because it overlaps with cardiac symptoms, new or unexplained chest pain should be checked by a professional.

Read this first. If you're having chest pain right now and you're not sure — treat it as a possible heart attack and call emergency services (911 in the US, or your local number). You can't safely diagnose your own heart, and it's always better to be checked and told “it was only panic.”

A pounding heart, chest tightness, shortness of breath, a cold sweat, a sense of doom — panic attacks and heart attacks share many symptoms, which is exactly why panic is so terrifying. Below are the typical differences. Use them to understand what's happening, not to rule out a medical emergency.

Typical differences

The pain. Panic chest discomfort is often sharp, localized and shifts around; it may ease when you calm down. Classic heart-attack pain is more often pressure, squeezing or heaviness in the center of the chest.
Where it spreads. Pain radiating to the arm (often left), jaw, neck or back leans toward cardiac and needs emergency care.
Trigger. Panic often comes out of the blue or with anxiety. Cardiac pain is more likely to be brought on or worsened by exertion (climbing stairs, walking uphill).
Timing. Panic peaks within about 10 minutes and then eases. Heart-attack symptoms often persist or build and don't settle when you rest.
Tingling. Panic often causes tingling in both hands or around the mouth (from fast breathing); cardiac numbness is more likely in one arm.

Important: these patterns are typical, not reliable. Heart attacks can be “atypical” — mild, or without classic pain — especially in women, people with diabetes, and older adults. No article can safely diagnose chest pain. When in doubt, get checked.

Call emergency services now if you have:

Chest pressure or pain spreading to the arm, jaw, neck or back
Shortness of breath with the chest pain
A cold sweat, nausea or vomiting
Fainting or near-fainting
Symptoms brought on by exertion
Your first time with these symptoms, and you're unsure

If it turns out to be panic

Once serious causes are ruled out, the chest tightness of anxiety is real but harmless — it comes from tense muscles and rapid breathing. What helps: name it (“this is panic, not my heart”), slow your exhale (in for 4, out for 6), and ground your attention in the room. The more your brain learns these sensations are safe, the less power they have.
