Anxiety vs. Palpitations: How to Tell Them Apart
Anxiety and Palpitations are often confused but have distinct causes and clinical meanings. Learn the key differences, what each indicates, and when to seek urgent care.
Anxiety is a psychological state of apprehension and autonomic activation, while palpitations are an uncomfortable awareness of one's own heartbeat. Each can cause the other — anxiety triggers palpitations, and arrhythmia-induced palpitations trigger anxiety — making the distinction clinically challenging.
Clinical Context
Palpitations in the context of a normal ECG, normal thyroid function, and absence of structural heart disease are usually benign — often sinus tachycardia or ectopic beats driven by anxiety, caffeine, or dehydration. However, palpitations with syncope, family history of sudden cardiac death, or occurring during exertion require cardiac evaluation (Holter monitor, echocardiogram). Anxiety disorder is a diagnosis of exclusion: organic causes must be ruled out before attributing palpitations to a primary psychiatric condition.

Anxiety vs. Palpitations: How to Tell Them Apart+
Anxiety is a psychological state of apprehension and autonomic activation, while palpitations are an uncomfortable awareness of one's own heartbeat. Each can cause the other — anxiety triggers palpitations, and arrhythmia-induced palpitations trigger anxiety — making the distinction clinically challenging.
How do I know if my palpitations are anxiety or a heart rhythm problem?+
Palpitations caused by anxiety typically occur with stress, resolve when calm, and are accompanied by other anxiety symptoms. Arrhythmic palpitations may be sudden in onset, feel like the heart flipping or stopping, occur at rest or during exertion, and may cause dizziness or fainting.
What tests diagnose palpitations?+
A 12-lead ECG is the first-line investigation. If the ECG is normal but symptoms recur, a 24–48 hour Holter monitor can capture intermittent arrhythmia. TSH (thyroid disease), FBC (anaemia), and electrolytes are also checked. Echocardiogram if structural heart disease is suspected.
When are palpitations dangerous?+
Seek urgent care if palpitations are accompanied by chest pain, breathlessness, dizziness, syncope, or family history of sudden cardiac death. Sustained rapid irregular rhythm, particularly in older patients or those with known heart disease, requires immediate ECG.
