Unforeseen Health Alerts: The Impact of Technology on Wellness
Michael Byrne, a sales manager in Tipperary, began to experience peculiar notifications from his Apple Watch. The device warned him of a concerning dip in his heart rate. Despite his active lifestyle, running four 5km races weekly, he felt completely fit and healthy. Yet, these alerts provoked a sense of unease.
Concerned, Byrne sought medical attention, prompting a thorough ECG examination. The results led him directly to the hospital.
There, doctors diagnosed him with ectopic heartbeats accompanied by premature ventricular contractions—conditions marked by irregular heartbeat patterns that disrupt normal cardiac rhythms. Following his assessment at Clonmel University Hospital, he underwent his inaugural surgery aimed at recalibrating the electrical signals within his heart.
“Although the first operation proved successful, it did not sufficiently reduce the ectopic beats, necessitating a subsequent procedure,” Byrne recounted.
“Presently, I’m in good health and undergoing regular check-ups. Doctors mentioned that, without the watch’s timely alerts, I might have succumbed to sudden death syndrome.
“Throughout this ordeal, I exhibited no symptoms; I maintained my routine of four 5km runs until my hospitalization.”
Byrne’s experience raises a significant question: Do smartwatches and health trackers possess the reliability we presume? Experts caution that while devices like these can unveil vital health insights, the pertinent challenge lies in the management of this data.
Dr. Cailbhe Doherty, an authority on wearables at University College Dublin, articulated to BreakingNews.ie that historically, such devices displayed variations in accuracy across different demographic profiles.
He highlighted studies revealing that blood pulse oximeters, which gauge blood oxygen levels, often lack precision when used on individuals with darker skin tones.
Nevertheless, the tide appears to be turning, as a recent initiative aims to incorporate a more heterogeneous sample pool in the development of smartwatch algorithms, taking into account the spectrum represented on the Fitzpatrick Skin Scale.
“The participant samples are notably diverse, generally comprising a balanced representation of genders. Numbers typically range between 5,000 and 10,000 individuals,” he explained.
“The objective is to reflect the broader population. While achieving this integrity is commendable, it is unlikely to encapsulate the entirety of human diversity amidst our 8 billion global population. Yet, progress is being made; biases once prevalent in algorithms are diminishing.”
Dr. Doherty also addressed gender disparities in wearable technology. “Current consumer wearables are only just beginning to address how a woman’s heart rate variability fluctuates throughout her menstrual cycle.
“Additionally, these devices may not function effectively for pregnant women.”
Concerns Regarding Personal Data
Dr. Doherty expressed apprehensions about the health and biometric data amassed by large corporations. “One of the most pressing issues often overlooked in the realm of wearables is the potency of this data,” he asserted.
“Wearables could potentially serve as a punitive system for individuals who fail to adopt healthy practices.” — Dr. Cailbhe Doherty
He cited VO2 max as an example, measuring how efficiently the body employs oxygen. “Beyond being a robust gauge of athletic prowess, it serves as a critical indicator of mortality risk,” he noted, adding that individuals with diminished VO2 max levels face a heightened risk of dying.
“These devices possess the capability to track factors critical to enhancing public health, encouraging physical activity, or projecting disease onset,” he elaborated.
“For instance, if I discern a declining trend in my VO2 max over a year or two, it may prompt me to consult my GP regarding potential underlying issues. However, in malevolent hands, such data could be weaponized against us.
“For individuals who have owned these devices for years, one must ponder what implications their data may have over the coming decades. This data harbors the potential to effectuate significant health advancements, yet it equally poses risks of penalization for those who neglect their health.”
“While some corporations treat data responsibly, others exercise laxity in its management.”
Safeguarding Personal Data
Dr. Doherty advocates for smartwatch users to diligently scrutinize the terms and conditions associated with their devices and understand how their data is utilized.
He also recommends consulting an annual report that evaluates the accuracy of various smartwatches.
“A straightforward indicator of a company’s quality may often be reflected in the extensiveness of their privacy policy,” he concluded.
“My vision for wearables includes universal ownership while ensuring comprehensive security and privacy over personal data, flagging early disease risk signs, and enabling proactive health measures across global populations.
If this vision is to be realized, data integrity must be upheld, ensuring it cannot be exploited against individuals.”
