The upper chambers quiver instead of squeezing. That raises stroke risk and often drains energy. Care here answers three questions in the first visit: stroke, rate or rhythm, and whether ablation belongs on the table.
Instead of a coordinated squeeze, the atria fibrillate. Blood can stagnate. The ventricle may race, pause, or both. People feel it as fatigue, breathlessness, fog, skipped beats — or feel nothing and learn it from a watch, a preoperative ECG, or a stroke workup.
Pattern matters. Paroxysmal AFib starts and stops. Persistent AFib stays until something interrupts it. Long-standing persistent disease has lived in the atrium long enough that isolation of the veins is only part of the story. The label on the chart is less important than a tracing captured during symptoms and a clear stroke-risk score.
Search results for “AFib specialist Houston” are hospital directories, device manufacturers, and EP sites that lead with a product name. Useful pages do the unglamorous work: name the rhythm, separate stroke prevention from symptom control, and say when ablation helps versus when it does not.
Precision Cardiology is a physician-owned electrophysiology practice. Dr. David Boone is board-certified in cardiovascular disease and clinical cardiac electrophysiology. He evaluates you, performs the procedure if there is one, and keeps the follow-up. That structure is the product.
1. Stroke risk. Anticoagulation is a separate decision from whether the heart is in sinus rhythm. CHA2DS2-VASc is a starting framework, not a slogan. If a left-atrial appendage device is ever relevant, that is a later conversation — after the score and the bleeding risk are honest.
2. Rate or rhythm. Some people do well with a quieter ventricle and no chase for sinus rhythm. Some do not: they stay tired, the ventricle is hard to control, or they are young enough that decades of AFib is a poor plan. Rhythm control can be a medication, a cardioversion, an ablation, or a sequence of those.
3. Is ablation on the table? Only after 1 and 2. If the job is pulmonary-vein isolation, pulsed field ablation is often the energy we discuss. Heat and freezing stay available. If the tracing is flutter, SVT, or PVCs wearing an AFib label, we treat the actual circuit.
An office ECG is a snapshot. A Holter records 24–48 hours. A patch or event monitor records days to weeks. An implantable loop recorder watches for months when events are rare — fainting, fleeting palpitations, a watch alert you cannot reproduce. Echo, thyroid labs, and a sleep-apnea history belong in the same pile because they change the plan.
Clinic hours Monday–Friday, 8am–5pm. One number: (832) 972-7300.
Procedures are performed at Houston Methodist, Memorial Hermann, Baylor St. Luke’s, and HCA hospitals across those same corridors.
New neurologic symptoms, fainting, chest pain, or severe shortness of breath are emergency-department problems — call 911. A new diagnosis, a watch alert you cannot ignore, medicines that made you miserable, or a cardiologist who mentioned ablation are clinic problems. Those can usually be seen this week.
No. Call the office. If another physician is sending records, fax (855) 538-7649. We typically contact the patient within one business day and send a consult note back.
Your cardiologist may manage uncomplicated AFib well. Come here when the diagnosis is still loose, ablation is being considered, antiarrhythmic choice is not straightforward, or a device may be part of the plan.
Not by itself. Stroke risk follows you, not the energy used in the lab.
No. PFA is used when isolation of the veins is the job and the anatomy fits. Conventional ablation remains the right tool for many flutters, SVTs, and selected AFib cases. Read how we use PFA.
