Arrhythmia Surveillance Program

The Arrhythmia Surveillance Program at Pomona Valley Hospital Medical Center is a comprehensive diagnostic service that monitors and evaluates heart rhythm abnormalities over time. Through continuous monitoring using advanced cardiac devices, such as implantable loop recorders or ambulatory ECG monitors, our team can identify and analyze arrhythmias, providing valuable insights into the frequency, duration, and triggers of abnormal heart rhythms.

Electrophysiology Study (EPS)

An Electrophysiology Study (EPS) is a specialized diagnostic procedure used to assess the heart's electrical activity and identify abnormal rhythms or conduction pathways. During an EPS, thin, flexible wires (electrodes) are inserted through veins and positioned within the heart chambers to record electrical signals. This information helps our electrophysiologists pinpoint the location and nature of arrhythmias, guiding subsequent treatment decisions.

Tilt Table Testing

Tilt Table Testing is a non-invasive diagnostic procedure used to evaluate patients with suspected neurally mediated syncope (fainting) or orthostatic hypotension. During the test, patients are secured to a specially designed table that can be tilted to different angles. Changes in heart rate, blood pressure, and symptoms are monitored to assess how the body responds to postural changes, aiding in the diagnosis of conditions related to blood pressure regulation and fainting episodes.

CARTO 3-D Mapping (EP 3-D Mapping)

Formerly known as CARTO 3-D Mapping, EP 3-D Mapping is an advanced imaging technology used during electrophysiology procedures to create detailed three-dimensional maps of the heart's electrical activity. By precisely mapping the heart's structure and electrical pathways, EP 3-D Mapping assists our electrophysiologists in locating abnormal electrical signals, guiding catheter-based interventions, and improving procedural accuracy and outcomes.

Electrophysiology Study (EPS)

An Electrophysiology Study (EPS) involves monitoring and recording the heart's electrical activity to diagnose and treat rhythm disturbances. This specialized test helps determine the underlying cause of arrhythmias and guides the selection of the most appropriate treatment. During the procedure, your cardiologist can safely reproduce your arrhythmia to identify its specific type and pinpoint the origin site of the abnormal heart rhythm.

EPS is often combined with Radiofrequency Ablation therapy during the same session, which can effectively cure certain arrhythmias. The procedure typically lasts between two to four hours, providing valuable insights into your heart's electrical function and paving the way for targeted treatment strategies.

At Pomona Valley Hospital Medical Center, our Electrophysiology Diagnostic Procedures are performed with precision and expertise, allowing us to deliver accurate diagnoses and tailored treatment plans for patients with cardiac rhythm disorders. If you require diagnostic evaluation for a heart rhythm condition or have concerns about your heart's electrical activity, our specialized cardiac team is here to provide comprehensive care and support throughout your journey to heart health.
