Electrophysiology

You might notice your heart racing, skipping beats or beating too slowly. You could also feel dizzy, lightheaded, short of breath, unusually tired or faint. Some heart rhythm problems happen without obvious symptoms, which is why testing can be important.

Electrophysiology is the study of the heart’s electrical system. It helps us see how the heart’s signals control its rhythm. Using this information, we can identify irregular heartbeats and guide care to support a steady heartbeat.

We use tests like EKGs, Holter monitors, wearable devices, implantable loop recorders and electrophysiology studies (EPS) to track the heart’s signals over time. These tests show when and where irregular rhythms happen so we can recommend the best approach for each heart.

Electrophysiologists are heart rhythm specialists who perform these tests and procedures. They conduct catheter ablation and implant pacemakers or defibrillators using their expertise to guide safe and effective treatment.

We carefully guide thin tubes called catheters through a vein to the heart. These catheters map the heart’s electrical signals to identify the source of any irregular heartbeat. The test helps us understand the type and location of the rhythm problem so we can plan care.

Most people feel only mild pressure or slight discomfort. We use numbing medicine and sedation to make sure you are comfortable. Most procedures are minimally invasive and recovery is quick.

Not always. Many rhythm issues can be managed with medicines or minimally invasive procedures like catheter ablation. Surgery is usually only needed in rare or complex cases.

Electrophysiologists can correct electrical signals in the heart with procedures, implant devices to regulate heart rhythm and prescribe medicines to control heart rate and rhythm. Each treatment plan is personalized to the needs of each heart.

Most people can return to usual activities soon after tests or procedures. Your care team will give clear guidance about activity levels during recovery and any precautions to take.

We provide instructions ahead of time, including guidance about medicines, fasting or other preparations. Following these instructions helps the study go smoothly and safely. Call your doctor's office if you have questions or have not received these instructions.

Yes. Electrophysiology tests are performed by experts using advanced technology. They are generally low risk even for older adults or people with other health conditions and most tests have little to no downtime.

It depends on your insurance. Some plans require a referral from a primary care doctor or cardiologist. Our team can help you check your coverage and schedule an appointment.

If you notice a fast, slow or irregular heartbeat, dizziness, fainting or shortness of breath, an electrophysiologist can help identify the cause and guide next steps. Even if symptoms seem mild or intermittent, early evaluation can provide peace of mind and guide care.
