Arrhythmia

An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include:

  • Fast or slow heart beat
  • Skipping beats
  • Lightheadedness or dizziness
  • Chest pain
  • Shortness of breath
  • Sweating

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.

Health Checkup

Regular health exams and tests can help find problems before they start. They also can help find problems early, when your chances for treatment and cure are better. Which exams and screenings you need depends on your age, health and family history, and lifestyle choices such as what you eat, how active you are, and whether you smoke.

To make the most of your next check-up, here are some things to do before you go:

  • Review your family medical history
  • Find out if you are due for any general screenings or vaccinations
  • Write down a list of issues and questions to take with you
