General Inquiries


Your cardiologist may conduct an Electrophysiology Study (EP study) for any of the following reasons:

  • To evaluate symptoms such as dizziness, fainting, weakness, palpitation, or others for a rhythm problem when other noninvasive tests have been inconclusive
  • To locate the source of a heart rhythm problem
  • To assess the effectiveness of medication(s) given to treat a heart rhythm problem
  • To treat a heart rhythm problem
A cardiac EP study can help Summa physicians pinpoint the location and type of an abnormal heart rhythm disturbance (arrhythmia) by showing how electrical impulses move through the heart.

During an EP study, small, thin wire electrodes are inserted through a vein in the groin or neck. The wire electrodes are threaded into the heart, using a special type of X-ray (fluoroscopy). Once in the heart, electrical signals are sent through the catheter to stimulate the heart tissue to try to trigger abnormal heart rhythm disturbances for evaluation. If the source of the arrhythmia or abnormal heart beat is found, an ablation (elimination of the area of heart tissue causing the abnormality) may be done.

The results of the study may help the doctor determine further therapeutic measures. An arrhythmia can sometimes be corrected with medication. However, if an arrhythmia is caused by an abnormal electrical pathway in the heart, our specialists offer several additional procedures to correct the problem, including implantable cardiac defibrillators (ICDs) and pacemakers.
