Arrhythmia

Types

Heart arrhythmias vary by types and degree of severity. A comprehensive diagnosis at Mayo Clinic helps determine the type of heart arrhythmia, its severity and what treatment may be most appropriate. Mayo Clinic provides patients of all ages with medical specialists and state-of-the-art facilities for diagnosing and treating all types of heart arrhythmias, including:

• Atrial fibrillation — In atrial fibrillation, the electrical signals in the upper chambers of the heart are disorganized and do not flow rhythmically through the heart muscle, causing an irregular heart rhythm.
• Atrial flutter — Atrial flutter is an abnormal conduction path within an upper chamber of the heart that usually results in a fast heart rhythm that can be regular or irregular.
• Bradycardia — Bradycardia is any heart rhythm that is too slow.
• Tachycardia — Tachycardia is any heart rhythm that is too fast.
• Wolff-Parkinson-White syndrome — This syndrome, a condition where the heart has an extra electrical pathway (circuit), may result in episodes of fast heart rhythm.
