Research

Doctors and surgeons trained in heart rhythm conditions are actively developing new technologies to treat these conditions. They're also working to improve care for people living with arrhythmias.

Areas of research have included:

  • Leading a multicenter, multinational trial to compare drug therapy with cardiac ablation for people with heart rhythm conditions.
  • Developing novel approaches to lower the risk of stroke in people with atrial fibrillation.
  • Designing new catheters to deliver ablation, including a state-of-the-art cryoablation balloon.
  • Understanding the genetics of heart arrhythmias.
