As a cardiac electrophysiologist, Dr. Phan has expertise in the treatment and ablation of various cardiac arrhythmias. He is skilled in both radiofrequency ablation and cryoablation methods for atrial fibrillation. He also employs forefront new technologies in 3D mapping and ablation to improve patient safety and outcomes.

Dr. Phan implants a wide spectrum of cardiac devices such as loop recorders, pacemakers, defibrillators, and bi-ventricular systems (or cardiac resynchronization therapy).
