Heart Rate & Rhythm (Arrhythmia) Care

Conditions that cause your heart to beat too fast, too slow, or at an irregular pace can be extremely distressing and disruptive. Fortunately, there are many treatment options available, from medications to catheter-based procedures to surgeries.

Our surgeons offer a variety of options for those dealing with atrial fibrillation, one of the most common irregular heart rhythms.  From the traditional Maze surgery to the less invasive surgical and endoscopic atrial fibrillation ablation techniques developed right here at Columbia, our surgeons have performed thousands of procedures for atrial fibrillation with outstanding results.
