Advanced Cardiac Electrophysiology & AFib Care in Houston
Precision Cardiology is Dr. David Boone’s physician-owned EP practice. We diagnose and treat AFib, flutter, SVT, ventricular arrhythmias, and slow rhythms — with pulsed field ablation, device therapy, and follow-up that stays with one physician.

What brings you in?
Most patients arrive with one of these four problems. Pick the closest match — you’ll see what we evaluate and how quickly you can be seen.
- 01
AFib or flutter
Irregular or racing beats, fatigue, shortness of breath, or a new diagnosis from your internist or cardiologist. AFib care →
- 02
Palpitations or fainting
Skipped beats, sudden racing, near-fainting, or unexplained syncope that still needs a diagnosis. Evaluate symptoms →
- 03
Pacemaker or ICD
Slow pulse, heart block, prior cardiac arrest risk, or a device that needs implant or long-term management. Device therapy →

Latest from the practice.
Two of the most powerful things you can do for AFib: Stop smoking. Cut back or quit alcohol—it's a common trigger ("holiday heart"). Even reducing drinks lowers AFib episodes. Good news: coffee in moderation is generally fine.
Educational only. Not medical advice.
Myth-buster: Aspirin is NOT an effective substitute for a blood thinner in AFib stroke prevention. If you need anticoagulation, aspirin won't do the job. Talk to your doctor about what's right for you.

He treats the person attached to the tracing — not only the tracing.
Pulsed field ablation, used with intent.
PFA treats AFib with brief electrical pulses instead of heat or freezing. The goal is a precise lesion on the tissue causing the arrhythmia, with less risk to nearby structures such as the esophagus and blood vessels.
No thermal energy · Tissue-selective · Often shorter procedure
Other circuits may need a different energy or no ablation. That decision is made on the map — the technology follows the diagnosis, not the other way around.
Every kind of rhythm, out of rhythm.
Atrial fibrillation (AFib)
The most common serious arrhythmia. Raises stroke risk and often drains energy.

Atrial flutter (AFL)
A fast, organized upper-chamber circuit. Typical flutter is often cured with ablation.

Supraventricular tachycardia (SVT)
Sudden racing from above the ventricles. Frequently curable in one procedure.
Sudden racing from above the ventricles. Frequently curable in one procedure.
Ventricular tachycardia (VT)
A dangerous lower-chamber rhythm that needs prompt, specialist evaluation.

Bradycardia & block (Brady)
A heartbeat too slow for the body. Pacemakers, including leadless options.

We hear the story
Symptoms, prior ECGs, monitors, and what has already been tried.
- 2
We capture the rhythm
ECG, wearable monitor, or implantable loop recorder if events are infrequent.
- 3
We choose the tool
Medication, ablation matched to the circuit, pacemaker, ICD, or watchful follow-up.

We stay with you
Dr. Boone performs the procedure and manages the long game — sleep apnea, blood pressure, stroke risk included.
