An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slowly, or with an irregular rhythm. When a heart beats too fast, the condition is called tachycardia. When a heart beats too slowly, the condition is called bradycardia.
Arrhythmia is caused by changes in heart tissue and activity or in the electrical signals that control your heartbeat. These changes can be caused by damage from disease, injury, or genetics. Often there are no symptoms, but some people feel an irregular heartbeat. You may feel faint or dizzy or have difficulty breathing.
An arrhythmia may not cause any obvious signs or symptoms. You may notice something that occurs only occasionally, or your symptoms may become more frequent over time.
TCM classify different causes of irregular heartbeat by looking at the whole concert of presenting symptoms:
Heart Qi deficiency or Blood deficiency: may happen after a long illness or loss of blood and be marked by heart palpitations, dizziness, memory problems, and/or insomnia. The pulse will be weak, and the tongue pale pink.
Kidney yin deficiency with Heart Fire: chronic illness can deplete the kidneys so that they can no longer manage the balance of fluids and heat, so heat rises and disturbs the Heart. With this presentation, a person may be experiencing strong feelings of fear or anger, depression, ringing in the ears (tinnitus), and stomach problems.
