Panic attack: symptoms peak within about 10 minutes, pass in 20 to 30, strike at rest, and carry tingling hands, air hunger, unreality, and doom. Heart attack: pressure or squeezing chest discomfort, often exertion-triggered, radiating to the arm, jaw, or back, building over minutes, with cold sweat or nausea.
The overlap is real, so the operating rule: a first-ever episode, or anything new about this one, gets evaluated as cardiac; an ECG settles it in minutes. Risk context shifts the odds: a young, healthy person with recognizable 10-minute surges leans panic; an older person with smoking, diabetes, or blood pressure history leans cardiac, and women and diabetics often present without classic chest pain at all. After a cardiac rule-out, panic is very treatable: CBT, SSRIs for prevention, breathing retraining for episodes. The rule that needs no pattern-matching: chest pressure with radiation, fainting, or symptoms that keep building means 911, and the paramedics can sort it out.
What to do
Common questions
Is it a panic attack or a heart attack?
The terrifying truth is that they can feel identical: chest tightness, racing or pounding heart, shortness of breath, sweating, dizziness, nausea. Both. That is why the operating rule is: if you have never had a diagnosed panic attack before, or anything about this episode is new, treat it as cardiac and get evaluated; an ECG is a five-minute test that settles it. The patterns that lean panic attack, per MedlinePlus's panic disorder description: symptoms surge to a peak within about 10 minutes and resolve in 20 to 30; they strike at rest, even waking you from sleep; and they carry the signature extras: tingling or numbness in the hands and around the mouth, air hunger with fast breathing, a sense of unreality, and a fear of dying or losing control that feels psychological as much as physical. The patterns that lean heart attack: a pressure, squeezing, or heavy discomfort (more than a sharp pain) in the center of the chest; triggered by physical exertion or heavy stress; radiating to the left arm, jaw, back, or stomach; building over minutes rather than peaking fast; with cold sweat, nausea, or unusual fatigue, and in women and diabetics sometimes without dramatic chest pain at all, just breathlessness, nausea, and exhaustion. Age and risk factors shift the prior odds: a healthy 25-year-old with episodic 10-minute surges leans panic; a 60-year-old smoker with diabetes leans cardiac. After a cardiac rule-out, the panic diagnosis opens real treatment: CBT works well, SSRIs help prevent recurrence, and breathing retraining shortens episodes. And the 911 rule needs no pattern-matching: chest pressure with radiation, fainting, or symptoms that keep building, call, and let the paramedics sort it out.
