Apple rolled out its ECG app for Apple Watch Series 4 yesterday with less fanfare, but no fewer questions about how the first portable consumer's cardiac monitoring tool will affect healthcare professionals.
"The idea that durable can be used by both patients and their healthcare professionals to manage and improve the health of the heart has promise and should also approach with caution to ensure that information and data are used responsibly and in collaboration with other evidence-based tools and guidelines , "American College of Cardiology President C. Michael Valentine, MD, said in an Apple release.
To take an ECG similar to a single-minded reading, consumers only keep their fingers on the watch's digital crown, and within 30 seconds, the heartbeat is classified as either atrial fibrillation (AF), sinus rhythm or incomplete. The waveforms can be stored on an iPhone and shared in a PDF with doctors.
"The role that technology plays for patients to capture meaningful data about what happens to their hearts, just when it happens, like the functionality of an on-the-go ECG, can be significant in new clinical care models and shared decision-making between people and their healthcare staff, "said Nancy Brown, CEO of the American Heart Association, in the Apple release.
The updated Apple Watch also has a warning feature that controls AF characters and alerts the user if it detects an irregular rhythm of five rhythm controls during at least 65 minutes.
Apple acknowledges that in the Apple Heart Study, however, the watch's AF warning was not confirmed 20% of the time of an ECG patch bears concurrently by study contestants.
Doctors took to Twitter after the app was publicized in Going with Daniel Yazdi, MD, Brigham and Women's Hospital, Boston, said: "Single lead ECG useful for detecting arrhythmias, not sensitive to ischemia. Spent on this new granularity, but benefit / damage to anticoagulation needs to be considered. "
Electrophysiologist Kevin Driver, MD, Charleston, West Virginia, tweeted:" Congratulations @leftbundle and the Apple Watch team. High quality ECG will recommend to patients. "
Others had a different opinion. Nishat Siddiqi, MD, University of Aberdeen, United Kingdom, tweeted:" Apple smart watch app for AF is exciting, but those with the highest risk of AF are older than the average smartwatch user and they Fake positive prices are too high. So, as a cardiologist, I will end up reassuring many anxious young people who do not have AF. "
Michael Katz, MD, @ MGKatz036, tweeted," Of course, as a heart rate specialist, I immediately installed the iOS update on Apple Watch to ECGs enabled. We're going to be broken. "
In response to Katz tweet, Kevin Woolf, MD, @ Kwoolfmd, Private Clinic, asked: "Job Safety / Children Through College".
News like the irregular heart disease messages are not meant for people who have been diagnosed with AF, also asked headlines in Washington Post and moan on Twitter. The electrophysiologist Edward J. Schloss, MD, The Christ Hospital in Cincinnati, tweeted: "Huh? Apple Watch 4 is not designed for those who have the most useful."
Electrophysiologist Paul Zei, MD, Brigham and Women & # 39; s Hospital and Harvard University, both in Boston, simply tweeted "Oh, The Irony …" 1
Medscape column and electrophysiologist John Mandrola, MD, from Baptist Health, Louisville, Kentucky, said that the app could misdiagnose patients due to inaccurate readings or lead to patient over treatment. time, "we can learn important things about arrhythmias from all of these data. Likewise, people will gain more health in terms of their heart rate."
By awarding novo approval for the new ECG app in less than a month , the US Food and Drug Administration stated that it is not intended for People under the age of 22, a point that someone suggested on Twitter could easily be worked around by changing the clock's user settings.
At the first release of the updates in September, Apple Williams, Chief Operating Officer, Jeff Williams was named "ultimate guardian of your health."
Apple executives sounded a more moderate tone yesterday.
"Apple Watch has helped so many people across the world, and we are humiliated for it's become such an important part of customer life," Williams said in Apple's statement. "With the release of these cardiac functions, Apple Watch takes the next step to give people more information about health."
Sumbul Desai, MD, Apple's Deputy CEO of Healing Th, noted, "We are confident that these features can help users get more informed conversations with their doctors. With the ECG app and irregular rhythm alert function, customers can get better understand aspects of their heart's health in a more meaningful way. "
