Your heart may feel symptoms of pounding, fluttering or beating irregularly, often for just a few seconds or minutes. You may also feel these sensations in your throat or neck. Sometimes you may feel an extra or missed beat, also called ‘ectopic beats’. Episodes of palpitations accompanied by other symptoms, such as dizziness or tightness in your chest, can sometimes be a sign of a heart problem.
Palpitations may be triggered by a surge of adrenaline, a hormone your body releases after you have overexerted yourself or when you feel nervous, anxious or excited. Eating rich, spicy foods, drinking excessive amounts of caffeine or alcohol, smoking, and using recreational drugs can all bring on palpitations. You should reduce your intake of coffee or energy drinks and avoid using recreational drugs.
