Researchers identify a genetic mutation that sets the heart racing, producing an irregular heartbeat that can lead to heart failure.
As a young woman, Martha Aston knew something wasn’t right.
“I was preparing for my junior piano recital in college and I just didn’t feel good,” she said. “Performing one piece of music exhausted me.”
Beyond the bone-grinding fatigue, she also could not catch her breath. During a routine medical check-up a few months later, her doctor paused while listening to her heart.
“He asked me if I knew I had an irregular heartbeat,” she said.
