Rosalee Johns says she has her life back thanks to a freezing therapy called cryoablation that restored her heartbeat to normal.
In 2008, Johns, then age 67, was diagnosed with atrial fibrillation, a condition in which the atria — the upper chambers of the heart — receive irregular electrical impulses that cause erratic heartbeats. Johns’ heart beat rapidly. She was light-headed and short of breath. The episodes occurred every three or four weeks, lasting 12 to 15 hours. Despite treatment with medication, the episodes increased to almost daily.
