Stanford study finds Apple Watch can detect irregular heart rhythms
Stanford has released the results of its Apple Watch-based heart study more than a year after it began, and it appears to have been a success, with a few caveats. Only 0.5 percent of the more than 400,000 volunteers received warnings of irregular heart rhythms, but physicians later verified that 84 percent of those notifications were atrial fibrillation episodes and thus potential signs of trouble. To put it another way, the technology both avoided a glut of false positives (a major concern going into the study) and was reliable enough that it was worth a follow-up with doctors.
Fitbit data led doctors to shock a patient's heart
Doctors made a decision to shock a man's heart back to rhythm based on his Fitbit data, showing that such devices can do far more than just track your exercise. The 42-year old patient arrive at an ER in Camden, New Jersey with an atrial fibrillation (a fast and irregular heartbeat), meaning he needed immediate medical treatment. But which kind? Using a defibrillator could trigger a stroke in some cases, but not using one could also trigger a stroke. Luckily they noticed he was wearing a Fitbit, and its data confirmed his abnormal heart rate happened around the same time he had a seizure.
Robot surgeon performs world's first unassisted operation
We're sure that more than a few of our readers are keen on robots and interested in the latest developments in robotics, but how many of you would volunteer to be the guinea pig for the world's first unassisted heart surgery? Even though there were about a million doctors on hand to monitor Dr. Carlo Pappone's robosurgeon doing its detailed work on a 34-year-old Italian patient suffering from atrial fibrillation (heart flutters), we can't help but wonder if a juxtaposed "0" and "1" in the bot's code is all it would take to drive a scalpel somewhere that it isn't supposed to go. Luckily for the pioneering patient, the 50-minute surgery went off without a hitch, most likely due to the fact that the prototype bot has software containing data about some 10,000 real-world operations, and has already performed assisted procedures on at least 40 people. Pappone, who initiated and monitored the latest surgery from a computer in Boston while it was occurring in Milan, plans to release a commercial version of the unnamed robosurgeon later this month.[Via PhysOrg]
