Arrhythmia Symptoms

The following are common arrhythmia symptoms:

  • Shortness of breath
  • Chest pain
  • Palpitations or rapid thumping in your chest
  • Feeling tired or light-headed
  • Passing out

Call your doctor if you have any of the above symptoms of arrhythmia, especially if you have heart disease or have had a heart attack.

The heart has four compartments, or chambers. The walls of the heart squeeze together (contract) to push blood through the chambers. The contractions are controlled by an electrical signal that begins in the heart's natural "pacemaker" (called the sinoatrial node). The rate of the contractions is influenced by nerve impulses and hormones in the blood. A problem in any of these can cause an arrhythmia.

Minor arrhythmias may be caused by excessive alcohol use, smoking, caffeine, stress or exercise. The most common cause of arrhythmias is heart disease, abnormal heart valve function and heart failure. However, arrhythmias can occur for no known reason.
