Tseng, M.D. ResearchMayo Clinic researchers are working to better understand the genetic, electrical and structural causes of Brugada syndrome. Through the Sudden Death Genomics Laboratory and Cardiovascular Research Center, investigators are studying disease-causing genes, identifying new risk factors, improving diagnostic testing and exploring evidence that Brugada syndrome may involve both irregular heartbeats and structural changes in the heart. This work aims to improve early detection, more accurately predict who is at risk of life-threatening arrhythmias, and develop more personalized approaches to treatment and prevention.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
