Our Services
Our electrophysiology program provides comprehensive evaluation and management of cardiac rhythm disorders, utilizing advanced diagnostic tools, catheter-based therapies, and device-based treatments. Care is tailored to each patient with a focus on precision diagnosis, guideline-directed therapy, and long-term rhythm management.
We offer advanced ablation technologies, including pulsed field ablation (PFA), representing the next generation of atrial fibrillation treatment.
Cardiac Arrhythmia Evaluation & Management
Comprehensive arrhythmia consultation

These therapies improve symptoms, ventricular function, and outcomes in appropriately selected patients with heart failure and conduction disease.
Conduction System & Physiologic Pacing
His-bundle pacing
Left bundle branch area pacing (LBBAP)
Physiologic pacing strategies aim to preserve normal ventricular activation, reducing the risk of pacing-induced cardiomyopathy and improving long-term cardiac function.
Implantable & Ambulatory Rhythm Monitoring
Implantable Loop Recorder (ILR) implantation
Holter monitoring (24–48 hour)
Extended ambulatory monitoring (patch/event monitors)
Remote device and rhythm monitoring
These technologies enable long-term rhythm surveillance and improve detection of intermittent or asymptomatic arrhythmias.
Catheter Ablation Procedures

Atrioventricular nodal reentrant tachycardia (AVNRT) ablation
Atrioventricular reentrant tachycardia (AVRT) / WPW ablation
Atrial tachycardia ablation
Typical and atypical atrial flutter ablation
Atrial Fibrillation
Pulmonary vein isolation (PVI)
Ablation for persistent and long-standing persistent atrial fibrillation
Posterior wall isolation
Linear ablation strategies (roof line, mitral isthmus)
Redo atrial fibrillation ablation
Pulsed Field Ablation (PFA)
- Pulsed Field Ablation (PFA) is an advanced, non-thermal ablation technology that uses high-energy electrical fields (electroporation) to selectively target cardiac tissue responsible for atrial fibrillation while minimizing injury to surrounding structures such as the esophagus, phrenic nerve, and pulmonary veins.
- PFA offers:
- Tissue-selective ablation with reduced collateral damage
- Shorter procedure times in many cases
- Potentially improved safety profile compared to traditional thermal ablation (radiofrequency or cryoablation)
- Rapidly evolving evidence supporting its use in atrial fibrillation treatment
This technology represents the next generation of atrial fibrillation ablation and is incorporated into our approach for appropriately selected patients.
Ventricular Arrhythmias
Ventricular tachycardia (VT) ablation
Premature ventricular contraction (PVC) ablation
Epicardial VT ablation (selected cases)
Catheter ablation offers definitive treatment for many arrhythmias, improving symptoms, reducing arrhythmia burden, and in selected cases improving survival.

Frequently Asked Questions
What is an electrophysiology (EP) study?
An EP study is a minimally invasive procedure used to evaluate the electrical system of the heart. It helps identify the source of abnormal heart rhythms and guides treatment decisions, including catheter ablation.
What is catheter ablation?
Catheter ablation is a procedure that uses heat (radiofrequency) or cold (cryoablation) energy to eliminate abnormal electrical pathways in the heart. It is often used to treat atrial fibrillation, supraventricular tachycardia, and certain ventricular arrhythmias.
When should atrial fibrillation be treated with ablation?
Ablation is considered in patients with symptomatic atrial fibrillation, particularly when medications are ineffective or not well tolerated. Current guidelines support ablation as an effective therapy to improve symptoms and quality of life.
What is a pacemaker and when is it needed?
A pacemaker is a small device implanted to regulate slow or irregular heart rhythms. It is typically recommended for patients with symptomatic bradycardia or conduction system disease.
What is the difference between a pacemaker and a defibrillator (ICD)?
A pacemaker treats slow heart rhythms, while an implantable cardioverter-defibrillator (ICD) can detect and treat life-threatening fast arrhythmias by delivering a shock when needed.
What is an implantable loop recorder (ILR)?
An ILR is a small device implanted under the skin that continuously monitors heart rhythm for extended periods. It is useful for diagnosing infrequent arrhythmias, unexplained syncope, or detecting atrial fibrillation after stroke.
Are EP procedures safe?
Electrophysiology procedures are routinely performed and generally safe. Risks vary depending on the specific procedure and patient factors. Your electrophysiologist will review risks and benefits in detail prior to treatment.
What is pulsed field ablation (PFA)?
Pulsed field ablation (PFA) is a newer ablation technique that uses electrical energy rather than heat or cold to treat atrial fibrillation. It is designed to selectively target heart tissue while minimizing damage to surrounding structures, and is emerging as a promising advancement in AF treatment.
