A panic attack can cause a pounding heart, chest discomfort, sweating, trembling, dizziness, tingling, nausea, shortness of breath, and fear of dying or losing control. These sensations can resemble a heart attack, arrhythmia, asthma flare, blood clot, medication reaction, or another medical condition.
Call 911 when symptoms may be life-threatening
- Chest pressure or pain with sweating, nausea, fainting, or pain spreading to the arm, back, neck, or jaw.
- Severe shortness of breath, blue or gray lips, or inability to speak normally.
- Fainting, seizure, sudden confusion, or new one-sided weakness.
- A very fast or irregular heartbeat with collapse, severe chest pain, or major breathing difficulty.
- Symptoms after a new medication, drug, allergic exposure, surgery, pregnancy complication, or known heart or lung condition.
Clues that may fit a panic pattern—after safety is checked
- A rapid wave of fear with several body symptoms that peaks and gradually settles.
- Similar episodes have been evaluated and a clinician provided a panic plan.
- Symptoms occur with anticipatory fear, crowded places, driving, or body monitoring.
- Tingling and lightheadedness increase with fast, deep breathing.
- Fear of another attack leads to avoidance and repeated checking.

Safety first, then orientation
- Compare the episode with your clinician-approved emergency plan.
- Sit or stand somewhere physically safe.
- Name where you are, the date, and what is actually happening.
- Allow breathing to become gentle and quiet.
- Relax the jaw and lower the shoulders.
- Stay with a simple task or supportive person until the wave decreases.
What to discuss with a clinician
Ask whether you need an electrocardiogram, medication review, thyroid or anemia evaluation, or assessment for asthma, sleep apnea, reflux, or stimulant effects. If panic is likely, ask about cognitive behavioral therapy, interoceptive exposure, medication, and a written future plan.
Key takeaways
- Panic can produce intense heart and breathing symptoms.
- A first or different episode needs medical judgment.
- Red flags override a history of anxiety.
- Effective treatment targets fear and avoidance.
