Heart Rhythm Services

Cardiac Electrophysiology is the study of the electrical system of the heart. The heart’s electrical system controls the contractions that keep the blood pumping and circulating throughout the body. SCHI electrophysiologists perform procedures at Rochester General Hospital and Unity Hospital. Consultations are available at all of our locations

Cardiac Electrophysiology Consultation

One of our electrophysiologists will evaluate your symptoms and any testing you may have already had as well as any medications you are on and your family history. Any further testing or procedures that become necessary will be explained clearly for all patients. We welcome you to ask questions and recommend that you have someone with you for your appointments. We want you to feel completely comfortable with your treatment plan.

Device Management Clinic

Patients with devices are scheduled for necessary telephone checks as well as in office checks to ensure that your device is working properly. This process will be thoroughly explained to patients who have devices. SCHI also jointly sponsors an Implantable Cardiac Defibrillator (ICD) support group, you can view further information regarding this on our ICD facebook fan page: Jumpstart

Implantable Cardiac defibrillator (ICD)

ICDs are devices that are used to treat rapid life-threatening rhythms. The device is implanted below the skin near the collarbone. Wires connect from the defibrillator to your heart. The device monitors every heart beat. If the device detects a certain abnormal heart rhythm (ventricular tachycardia or ventricular fibrillation) it will provide the needed therapy immediately.CRT (BiV Pacemaker and ICD)

Permanent pacemaker

A pacemaker is a device that treats slow heart rhythms (bradycardia). The device is implanted below the skin near the collarbone. Wires then connect the pacemaker to the heart. Electrical impulses are then delivered to the heart when needed.

Device Lead Extraction

Several years after a device is implanted, some cardiac pacemaker or defibrillator leads (wires) may need removal or replacement. This is referred to as Device Lead Extraction.


We specialize in endo/epicardial ablation, atrial fibrillation, SVT Ventricular Tachycardia. This is a minimally invasive procedure performed through catheters.

Cardiac Electrophysiology Study or EP Study

The term “electrophysiology study” or “EP study” applies to any procedure that requires the insertion of an electrode catheter into the heart. These catheters are flexible wires that transmit electrical currents to and from the heart. EP studies are used to diagnose heart rhythm abnormalities (arrhythmias).

Tilt Table

A tilt table test is used to evaluate the cause of syncope (unexplained fainting). You must bring someone with you for this test as you will not be allowed to drive home once the test is completed. You will be asked to lie on a table that moves from a horizontal to a vertical position. As the table changes positions your heart rate and blood pressure will continually be monitored.
