Palpitations occur when a person becomes aware of their heartbeat. The heartbeat may feel hard, fast, or uneven in their chest.[1][2]
Symptoms include a very fast or irregular heartbeat. Palpitations are a sensory symptom.[1] They are often described as a skipped beat, a rapid flutter, or a pounding in the chest or neck.[1][2]
Palpitations are not always the result of a physical problem with the heart and can be linked to anxiety.[3] However, they may signal a fast or irregular heartbeat. Palpitations can be brief or long-lasting. They can be intermittent or continuous. Other symptoms can include dizziness, shortness of breath, sweating, headaches, and chest pain.[2]
Palpitation may be associated with coronary heart disease, perimenopause, hyperthyroidism, adult heart muscle diseases like hypertrophic cardiomyopathy, congenital heart diseases like atrial septal defects,[4][2] diseases causing low blood oxygen such as asthma, emphysema or a blood clot in the lungs; previous chest surgery;[2] kidney disease; blood loss and pain; anemia; drugs such as antidepressants, statins, alcohol, nicotine, caffeine, cocaine and amphetamines; electrolyte imbalances of magnesium, potassium and calcium; and deficiencies of nutrients such as taurine, arginine, iron or vitamin B12.[5]
