Conditions · Houston, TX
Every kind of rhythm, out of rhythm.
Arrhythmias range from harmless to life-threatening. The first job is knowing which is which — then treating it precisely.
Conditions we treat
What we diagnose and treat.
Each of these has a different cause, a different risk profile, and a different right answer.
Atrial fibrillation
The most common serious arrhythmia. The upper chambers quiver instead of beating, which raises stroke risk and often leaves patients exhausted. Treatment ranges from rate and rhythm medication to catheter ablation.
Atrial flutter
A fast but organized upper-chamber rhythm. Because the circuit is predictable, ablation resolves typical flutter in a single procedure for the large majority of patients.
SVT
Sudden episodes of a racing heartbeat starting above the ventricles. Often curable with a targeted ablation, which means no lifelong medication.
Ventricular tachycardia
A fast rhythm arising from the lower chambers. This one warrants prompt evaluation, and treatment may involve medication, ablation, or a defibrillator depending on the cause.
Bradycardia & heart block
A heartbeat too slow to meet the body's needs, causing fatigue, lightheadedness, or fainting. A pacemaker, including leadless options, corrects the problem directly.
Palpitations
Skipped, fluttering, or pounding beats. Most are benign, but the job is to capture the rhythm during a symptom and prove which kind you have.
Syncope
Fainting or near-fainting. Some causes are harmless; some are electrical and serious. Ambulatory monitoring or an implantable loop recorder often settles the question.
PVCs
Extra beats from the ventricles. Common and usually harmless, but a high burden can weaken the heart over time and is worth treating.
How we get to an answer
Diagnosis first, then treatment.
An arrhythmia you cannot capture is an arrhythmia you cannot treat properly. Most evaluations start by recording the rhythm while you are having symptoms.
In-office evaluation
History, examination, and ECG at your first visit. Roughly 95% of clinic patients have an ECG the same day.
Ambulatory monitoring
Holter, extended wear patch, mobile cardiac telemetry, or event monitors, run in-house so results come back to Dr. Boone directly.
Implantable loop recorder
For infrequent symptoms. A small monitor placed under the skin in the office that watches the rhythm continuously for up to three years.
Imaging & stress testing
Echocardiography, carotid ultrasound, and treadmill stress testing, all available at our offices.
