Atrial Fibrillation Treated in Baltimore by Expert Doctors


Atrial fibrillation is a type of abnormal heartbeat called an arrhythmia. In atrial fibrillation, the two upper chambers of the heart, called the right atrium and left atrium, twitch in a fast and irregular pattern.

The cardiologists at The Heart Center at Mercy Medical Center in Baltimore, Maryland, are experienced in the diagnosis and treatment of atrial fibrillation, a condition that causes poor blood flow to the body.

About the Condition

Atrial fibrillation is an irregular or rapid heartbeat that can cause poor blood flow to the body. It is caused when the two upper chambers of the heart, known as the atrias, receive chaotic electric signals, causing them to quiver and beat out of sync and coordination with the heart’s lower two chambers, known as the ventricles.

Possible causes of atrial fibrillation may include but are not limited to:

  • High blood pressure
  • Heart attacks
  • Heart defects
  • Sleep apnea
  • Viral infections

Treatment Options

The goal in treating atrial fibrillation is to reset the heart regular rhythm. In some cases, this may be done by treating the underlying causes.

If an underlying cause cannot be found or cured, doctors will often use cardioversion to restore the heart’s normal rhythm.  This is typically done using electric shocks towards the heart through electrodes that are placed on the chest. In some cases, cardioversion is performed using medications.
