DR MARK WALSH, Sports Cardiologist & Heart Rhythm Specialist

Dr Walsh is a consultant congenital cardiologist with an interest in electrophysiology and inherited cardiac conditions. He trained in paediatric cardiology in Sickkids in Toronto and did his electrophysiology training in Cincinnati Children’s Hospital. After spending 6 years as a consultant in Bristol Children’s Hospital, Mark is now based in Dublin.

In addition to his post at Our Lady’s Children’s Hospital, Dr Walsh is also available at the Beacon Hospital on a regular basis to see paediatric patients and perform paediatric ablations. Given his interest in sport, he am also interested in screening young athletes for any conditions that may predispose to sudden arrhythmic death syndrome. In his personal time, Dr Walsh has a keen interest in tennis, rugby and mountain biking. Most importantly he is a dedicated family man, and can be seen here with his daughter Emily on holidays in Australia.
