Is it a panic attack or a heart attack?

Question

Accepted Answer

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.
