Conditions We Treat: Cardiac Arrhythmias

An arrhythmia is a disturbance in the regular rhythm of your heartbeat. The rhythm may be too fast, too slow or irregular. It is caused by a problem with the electrical signals that tell your heart muscle when to contract.

Arrhythmias: What You Need to Know

  • A precise diagnosis is necessary to pinpoint both the type and location of the electrical disturbance.
  • Some diagnostic tests are performed in an electrophysiology lab. Others consist of monitors you wear during your daily routine to detect less-frequent irregularities.
  • Your doctor’s goal is to correct the rhythm so your heart beats more efficiently.
  • Treatments include ablation, which destroys the group of heart cells producing “unauthorized” electrical signals; insertion of a pacemaker or implantable defibrillator, which correct the heart's rhythm using electricity; and medications.

The following conditions are common arrhythmias:

Atrial fibrillation
Atrial flutter
Atrial tachycardia
Bradycardia
Long QT Syndrome
Palpitations
Paroxysmal supraventricular tachycardia
Supraventricular tachycardia
Ventricular fibrillation
Ventricular tachycardia
