Adrenaline makes the heart beat faster and harder, and you become more aware of every beat. Palpitations can also cause anxiety, so the two often feed each other.
Signs that anxiety may be playing a part
- palpitations that build gradually and settle gradually
- a fast but regular heartbeat, usually under about 130 beats a minute
- other symptoms such as tingling, tight breathing, sweating or a sense of dread
- episodes linked to stressful situations, or that ease with distraction
Why a check is still worthwhile
Anxiety and heart rhythm problems can exist together. SVT, for example, is often first put down to panic attacks. Palpitations that start or stop suddenly, are very fast, feel irregular, or come with fainting should be assessed. Many people find that a clear explanation and a normal test result ease the anxiety itself.
What helps
Slow breathing (breathe in for 4 seconds and out for 6), regular exercise, good sleep, and less caffeine and alcohol. Talking therapies such as CBT are effective for anxiety; your GP can refer you, or in England you can refer yourself to NHS Talking Therapies.
Call 999 if palpitations come with chest pain, severe breathlessness, fainting or nearly fainting. For urgent advice, call NHS 111.
