Heart and Vascular Center

Electrophysiology Procedures

St. Mary performs more than 1,500 electrophysiology studies and procedures annually in our leading-edge EP labs - more than any other healthcare provider in our region. 


Irregular heartbeats are analyzed in EP studies

EP Studies use electrode catheters to help diagnose the origin and nature of an arrhythmia and assess the risk level. A study typically takes only an hour or two.

 The cardiac rate and rhythm of the heart is regulated by a complex electrical conduction system that is vital to sustaining life.

Abnormalities in the electrophysiology of the heart can result in cardiac arrhythmias (irregular heartbeats) and arrhythmia-related problems, including tachycardias (rapid heartbeat), bradycardias (slow heartbeat), syncope (fainting), heart palpitations and cardiac arrest.

Cardiac arrhythmias can occur in otherwise healthy patients or in the presence of other cardiovascular diseases.  Full evaluation of the cardiovascular system is part of the comprehensive care provided at St. Mary Medical Center.

Risk Assesssment
Diagnostic EP services used to detect arrhythmias include such monitoring techniques as EKG event recorders, 24-hour Holter and continuous-home telemetry. In addition, sophisticated signal-averaging processing techniques provide risk assessment of life-threatening arrhythmic disturbances.

Therapeutic EP Services include:

Pharmacologic Therapy uses medication to control.  Drug therapy is safe and effective for many patients. Using diagnostic tests and cardiac monitoring, EP experts can identify patients who may respond best to drug therapy.

Radiofrequency Ablation  to treat abnormalities in heart’s electrical system.
This treatment is standard therapy for a range of tachycardias.  Radiofrequency energy is delivered through a deflectable tip catheter to the culprit site.  Success rates for tachycardias are excellent.

Pacemaker Implantation to control heart rhythm.  Pacemakers are often indicated for patients experiencing bradyarrhythmias. Individualization is important in pacemaker selection, and the best device is selected for each patient after a comprehensive evaluation.  Pacemakers are routinely inserted in the electrophysiology lab using conscious sedation. The procedure usually takes one to two hours, and the patient is discharged the following day.

Implantable Defibrillator to jolt heart rhythm back to normal in cases of serious arrhythmia.
