Putting radiation to the test to heal irregularheartbeat. hearthealth health
While it's highly experimental, surprising early research suggests it may reprogram misfiring heart cells to control heartbeats more like younger, healthier cells do.

Then this winter, twice in about a month, Backus briefly passed out and awoke feeling like he'd been kicked in the chest. The defibrillator had to save him, shocking his heart back into rhythm.
Dr. Phillip Cuculich, a heart rhythm specialist at Washington University, came up with the idea for a no-incision alternative. But he agreed to try, warning patients about possible long-term risks. His very first arrhythmia patient responded,"You're concerned about something that might happen 10 or 20 years from now? I'm worried about tomorrow," Robinson recalled."That was really eye-opening."

"It may actually rejuvenate sick tissue, and that's pretty exciting," says Rentschler. - Courtesy of Washington University/Via Associated Press But the FDA requires stronger evidence for more routine use -- and the more hospitals offer"off-label" radiation to these heart patients, the harder it will be to get that proof.

Putting radiation to the test to heal irregular heartbeatDoctors are zapping the heart with radiation normally reserved for cancer in a bid to better treat a dangerous kind of irregular heartbeat. It's highly experimental. But researchers at Washington University in St. Louis have reported dramatic success with small numbers of severely ill patients who've exhausted standard care, and other hospitals are cautiously trying it. Now the first rigorous study is about to get underway to tell if the approach really works well enough for more routine use. Researchers think the one-time dose may reprogram misfiring heart cells to control heartbeats more like younger, healthier cells do.
