Cardiac electrophysiology for Energy Corridor patients

The Energy Corridor along the Katy Freeway is home to a large population of corporate professionals, many at the major energy firms, along with active retirees and families. Patients here are typically well-informed, schedule-driven, and value a specialist who returns calls quickly.

Heart rhythm conditions don’t respect neighborhood lines. The most common reasons Energy Corridor patients are referred to our practice are atrial fibrillation, supraventricular tachycardia, unexplained fainting, and questions about pacemakers or defibrillators. Our office is about a 20 to 25-minute drive from Energy Corridor.

Same-day notes to your referring physician. If your primary care doctor or cardiologist sent you, they will hear from us the day we see you, with the rhythm interpretation, the plan, and the timeline.
