Cardiac Arrhythmia Research

Our research program is very patient focused. In general we have two criteria when considering starting a new project.  Firstly, is there an important clinical research question to be answered?  Secondly, does our group have the necessary experience, skills, resources and collaborations to be able to answer the question?
