Several heart-related diseases and conditions can be detected and treated using electrophysiology. To learn more, click on the links below.

In general arrhythmias arise from either the upper chambers of the heart called the atria or the lower chambers of the heart called the ventricles. Arrhythmias from either chamber of the heart can lead to symptoms that impair quality of life by limiting exercise capacity. When uncontrolled, they can lead to heart failure, fainting, or even life-threatening symptoms such as sudden cardiac arrest. It is important to have a clear understanding of which type of arrhythmia you have - which only you and your physician together can determine.


  • Palpitations: the word used to describe the feeling of irregular heart rate.
  • Syncope: repeated fainting of unknown cause; can be serious and should not be ignored.

Types of Cardiac Arrhythmias and Heart Rhythm Problems

  • Fast Heart Rate: a condition in which the heart beats at an abnormally fast rate of more than 100 beats per minute, known as tachycardia.
  • Irregular Heart Rhythms: feelings or sensations that your heart is pounding or racing, sometimes called palpitations.
  • Slow Heart Rate: a heart rate lower than 60 beats per minute, also known as bradycardia.
  • Congestive Heart Failure: a condition in which the heart cannot pump enough blood to the rest of the body.
  • Sudden Cardiac Arrest: when the heart suddenly and unexpectedly stops beating. This is generally due to an electrical disturbance of the heart.

Atrial Arrhythmias

  • Atrial Fibrillation (Afib): an irregular and often rapid heart rate that involves the upper chambers of the heart, called the atria.
  • Atrial Flutter: another type of irregular heartbeat that involves the upper chambers of the heart, called the atria.
  • Atrial Tachycardia: a rapid heart rate that occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles).
  • Premature Atrial Contractions
  • Supraventricular Tachycardia: episodes of rapid heart rate that start in a part of the heart above the ventricles, including Wolff-Parkinson-White, AV nodal re-entry, inappropriate sinus tachycardia, focal atrial tachycardia and junctional tachycardia.

Ventricular Arrhythmias

  • Premature Ventricular Contractions
  • Nonsustained Ventricular Tachycardia
  • Ventricular Fibrillation: an abnormal heart rhythm involving the ventricles, or lower chambers, of the heart, that can be life-threatening
  • Ventricular Tachycardia: a rapid heartbeat that starts in the ventricles, or lower chambers, of the heart
