Electrophysiology Disorders

Electrical impulses control the beating of the heart and under normal circumstances, are the natural pacemaker of the heart. However, sometimes abnormal circuits or pathways develop, leading the heart to beat too fast or too slow. These are called arrhythmias. Left untreated, arrhythmias can lead to heart disease or stroke.

MCH Electrophysiology doctors treat the following heart rhythm disorders:

  • Atrial Fibrillation, or AFib, is one of the most common heart rhythm disorders, affecting more than 33.5 million people worldwide. The disease causes a patient’s heart to beat so fast that blood is not pumped completely out of the upper chambers (atria) of the heart. This is dangerous because the blood pools and may clot. If left untreated, patients who have AFib are 5 times more likely to have a stroke. In addition, AFib patients are more likely to develop heart failure. Common symptoms include fainting, weakness, dizziness, shortness of breath, and heart palpitations.
  • Atrial flutter happens when the fast contractions of the upper chambers of the heart spread to the lower chambers, causing rapid heartbeats. Symptoms may include shortness of breath, dizziness, or heart palpitations (racing heart).
  • Atrioventricular nodal reentrant tachycardia (AVNRT) is a type of fast rhythm of the heart. It is more common in women than men and the main symptom is heart palpitations.
  • Wolf Parkinson White (WPW) is another disorder of the heart’s electrical system. In this disorder, the ventricles of the heart contract too early. Patients who have WPW may not have symptoms, or may have shortness of breath, dizziness or palpitations.
  • Atrial tachycardia happens when the electrical impulse comes from an abnormal site and the heart beats very fast.
