Symptoms of a Panic Attack

Ruling Out Heart AttackPanic attacks and heart attacks share symptoms. Seek emergency care if: chest pain is central and crushing, spreads to arm or jaw, persists more than 20 minutes, comes on with exertion, or you are over 40 with risk factors. Don't assume it's 'just anxiety'.

Blood Tests Your Doctor May Order

TestRules Out
Thyroid (TSH / T4)Hyperthyroidism causes panic-like symptoms
Blood glucoseHypoglycaemia causes tremor, anxiety, palpitations
FBCAnaemia causes breathlessness and palpitations
ECGArrhythmias (SVT) can mimic panic attacks
Cortisol (24h urine)Phaeochromocytoma (rare tumour) causes episodes of panic + high BP
ElectrolytesLow magnesium or potassium causes palpitations
The 5-4-3-2-1 TechniqueDuring a panic attack: name 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell, 1 you can taste. This grounds you in the present and interrupts the fight-or-flight cycle.

Evidence-Based Treatments

TreatmentEffectivenessNotes

SSRI antidepressantsVery effectiveTakes 4–6 weeks to work
BenzodiazepinesFast relief but not long-termRisk of dependence — short-term only
Beta-blockers (propranolol)Reduces physical symptomsUseful for specific situations

Can panic attacks cause physical harm?
No. Despite feeling terrifying, panic attacks do not cause heart attacks, fainting (blood pressure actually rises), or brain damage. Understanding this is central to recovery.
Will I always have panic attacks?
With treatment (especially CBT), most people recover fully. Even without treatment, panic disorder often reduces naturally over time.
What triggers panic attacks?
Common triggers include stress, caffeine, alcohol withdrawal, certain medications (e.g. stimulants), medical conditions, and learned fear responses from a previous attack.
