Whether you have symptoms and what those symptoms feel like depend on the health of your heart and the type of arrhythmia you have. Symptoms also depend on:

  • How severe the arrhythmia is
  • How often it happens
  • How long it lasts

Some arrhythmias do not produce any warning signs. Contrary to popular belief, heart palpitations do not always mean that you have an arrhythmia.
