Researchers at St. George's Hospital in London are testing whether cells collected from a simple cheek swab can help diagnose inherited heart rhythm disorders — conditions that run in families and can cause dangerous irregular heartbeats. The study involves people who have been diagnosed with these conditions and family members who may carry the genetic risk. This test is completely painless and safe, and previous research showed it was very accurate at identifying who has or carries these conditions.
Some inherited heart rhythm disorders are rare and hard to diagnose, while others are more common but still dangerous. A simple, painless cheek swab could help doctors identify family members at risk before serious problems develop — potentially preventing life-threatening complications. Right now, doctors rely on more invasive tests like heart scans and ECGs.

You would visit St. George's Hospital and have a simple cheek swab taken — similar to a mouth rinse or gentle scraping of the inside of your cheek. This takes just a few minutes and causes no pain or discomfort. The cells are then analyzed in the lab to look for patterns that may indicate disease risk. You do not need to return for follow-up visits, and there are no medications or procedures involved.
