Information for Patients


Also called: Irregular heartbeat

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.

Fetal Health and Development

A normal pregnancy lasts nine months. Each three-month period of pregnancy is called a trimester. During each trimester, the fetus grows and develops. There are specific prenatal tests to monitor both the mother's health and fetal health during each trimester.

With modern technology, health professionals can

  • Detect birth defects
  • Identify problems that may affect childbirth
  • Correct some kinds of fetal problems before the baby is born

  • Developmental disorders of the female reproductive tract
  • Fetal development
  • Intrauterine growth restriction
