Electrophysiology

Houston’s Trusted Heart Rhythm Specialists
CLS Health cardiologists bring advanced expertise and a personal approach to every patient. Electrophysiology, a subspecialty of cardiology, focuses on diagnosing and treating irregular heart rhythms such as atrial fibrillation (AFib), bradycardia, and supraventricular tachycardia (SVT).
Our board-certified electrophysiologists provide compassionate care for symptoms like palpitations, dizziness, fainting, or irregular heartbeats. Whether you’re exploring alternatives to blood thinners like the Watchman™ procedure or seeking advanced therapies such as Pulse Field Ablation (PFA), our team is here to guide you toward long-term heart rhythm control.
With heart rhythm clinics across Greater Houston, we provide complete cardiovascular care—from hypertension and coronary artery disease to complex arrhythmias. Known for their thorough, patient-focused care, our cardiologists are consistently rated among the top in patient satisfaction.
When should I see an electrophysiologist?
Your doctor may also refer you to an electrophysiologist if tests reveal an abnormal heart rhythm or if you have a condition like atrial fibrillation, supraventricular tachycardia, or ventricular arrhythmia. An electrophysiologist is the right specialist to determine if you could benefit from treatments like catheter ablation, a pacemaker, or an implantable defibrillator.
Our team is here to provide answers and advanced care tailored to your needs. If you're unsure, a consultation can help you understand your heart health and take the right next step.
We welcome self-referred patients and referrals from all specialties, including neurologists for loop recorders following a cryptogenic stroke. Second opinions are also welcome.

Our electrophysiologists specialize in treating a wide range of rhythm-related conditions:
- Atrial fibrillation (AFib)
- Atrial flutter
- Supraventricular tachycardia (SVT)
- Bradycardia (slow heart rate)
- Heart block

- Electrophysiology (EP) studies
Imaging tests like echocardiography, cardiac MRI, or CT angiography may also be used to evaluate heart structure and guide treatment decisions. These tests help pinpoint the cause of abnormal rhythms and guide the most effective therapy plan.
Electrophysiology Procedures
Our procedures are minimally invasive, precise, and often same day:
- Electrophysiology (EP) studies
- Catheter ablation – including Pulse Field Ablation (PFA), a safer, faster, and more effective technique for treating AFib
- 3D electroanatomic mapping
- Pacemaker implantation
- Implantable cardioverter-defibrillator (ICD) implantation

- Implantable loop recorders
- Watchman™ device implantation – an alternative to long-term blood thinners for stroke prevention
- Device checks and remote monitoring
Clinical Research
We participate in national and international clinical trials to bring the latest technology and treatment options to our patients. These trials help us offer early access to promising therapies and shape the future of electrophysiology.
Professional Leadership
Our electrophysiology team trains physicians and industry professionals nationwide. Trainees frequently visit our clinic to observe cutting-edge workflows in pacemaker and ablation procedures.

FAQs
Recognizing heart attack symptoms early is crucial. Common signs include chest pain or discomfort (pressure, squeezing, or fullness), shortness of breath, upper body pain (arms, back, neck, jaw, or stomach), nausea or vomiting, cold sweats, and dizziness. If you or someone else experiences these symptoms, seek immediate emergency medical attention.
Atrial Fibrillation (AFib) is an irregular heart rhythm that increases stroke risk. Treatment options include medications to control heart rate and prevent blood clots, cardioversion to reset the heart's rhythm, and catheter ablation to destroy abnormal heart tissue. Lifestyle changes, such as stress management and maintaining a healthy weight are also important. In some cases, a pacemaker may be implanted. Early diagnosis and treatment of AFib can prevent complications.
Pacemakers are used for conditions that cause the heart to beat too slowly, irregularly, or with dangerous pauses. They help regulate rhythm, maintain steady blood flow, and reduce symptoms like fatigue, dizziness, or fainting.
Heart Conditions That May Require a Pacemaker:
- Bradycardia – when the heart beats too slowly.
- Heart block (AV block) – when electrical signals between the upper and lower chambers of the heart are delayed or blocked.
- Sick sinus syndrome – when the heart’s natural pacemaker (sinus node) doesn’t work properly, causing alternating slow and fast rhythms.
- Atrial fibrillation with slow ventricular response – when AFib causes the lower chambers of the heart to beat too slowly.
- Congenital heart disease – some people are born with electrical system abnormalities that require pacing support.
- Post–heart surgery or heart attack rhythm problems – when the heart’s electrical system is damaged and doesn’t recover.
Recent advancements in heart disease treatment include minimally invasive procedures like TAVR, advanced imaging technologies for earlier diagnosis, wearable health devices for real-time monitoring, personalized medicine, regenerative therapies, robotic surgery, and expanded access through telemedicine.
