Figuring out the breadth of Apple’s market share and the prevalence of undiagnosed hypertension, these alerts have the potential to overburden present health-care techniques and trigger affected person anxiousness.
As these units change into extra mainstream, health-care techniques could must adapt to accommodate the rising variety of sufferers looking for care.
