Panic Attacks… or a Heart Rhythm Issue?
A sudden racing heart can feel terrifying — and it’s not always “just anxiety.”
Panic attacks and heart rhythm abnormalities can look very similar. Both can cause a rapid heartbeat, shortness of breath, dizziness, and chest tightness. In the moment, they can feel indistinguishable.
While panic disorder is common and treatable, certain cardiac rhythm problems can present with nearly identical symptoms.
Seek urgent medical evaluation if you experience fainting, chest pain that spreads to the arm or jaw, symptoms that occur during exertion, or if you have known cardiac risk factors.
Never assume chest symptoms are “just anxiety.”
If something feels intense, new, or different from your usual experience, seek prompt medical care.
