Why is Apple Good for you

Are Apples Good for you

The previous episode of this article would have remained un-written, but for the fact that when the company forgets the balance sheet and trying to procure another grand out of it’s followers (who just happen to be about the most loyal brand customers in the world), by selling us an additional 200 pixels, or a second simcard slot (iPhone), or an unscrambled menu, or brighter colours, or a new strap release (iWatch), or wireless ear-buds, or another incompatible USB port. When it turns to it’s original philanthropic and groundbreaking ethos, Apple really does light-up the world in a new and awe inspiring glow.


Causes of Irregular heartbeat

I think that it was back in around November 2017, when Apple announced ( to much of the usual Apple trumpet and fanfare) that it was about to join forces with Stanford University’s School of Medicine, in a Heart Study utilising their newly revamped heart rate monitor in the Apple Watch.


The Apple Watch can notify wearers of possible atrial fibrillation, which results in 130,000 deaths and 750,000 hospitalisations each year, according to the CDC.

The initial results of which have just been released, and honestly they are astounding. Not only for the fact the enormity of the numbers. The study was drawn from 400,000 participants, which easily makes it the most broadly sampled heart study ever undertaken.

Atrial Fibrillation

Atrial Fibrillation (irregular heartbeat) causes over 750,00 hospitalisations per year and over 130,000 deaths, in the US, alone. Effecting upwards of around 6.1 million Americans, the condition often goes un-noticed, and un-diagnosed because the victim rarely suffers on a daily basis.

The Apple heart rate monitor is capable of picking up Atrial Fibrillation, and so this capability was at the centre of the study.

The App

The standard heart rate App was modified to specifically monitor for signs of irregular heart rate, and when detected an advisory message was placed on-screen instructing the wearer to book a telephone consultation with a doctor working on the study. The patients were then sent (AECG) ambulatory electrocardiography patches, which measured the heart rate for up to a week.

Apple test study running since 2017, proves that Apple does have a heart.

The preliminary results have been nothing short of impressive.
Comparing the irregular pulse detection on the Apple Watch to ECG patch recordings showed the pulse detection algorithm had a 71% positive predictive value. 84% of the time, the participants who received notifications were found to be in atrial fibrillation at the time. 57% of those who received irregular pulse notifications sought medical attention. Providing hard evidence of the potential benefits of wearing devices equipped with a passive heart rate monitor.

Laying Fears to Rest

One of the biggest barriers to the acceptance of such wearables by the medical fraternity has always been the perception that they would cause a spike in patients seeking medical help due to over reporting, so negating any benefits to be gained by early reporting.

So possibly the key finding of the study was that out of 419,093 participants, only 0.5% of participants (2,116) received irregular pulse notifications.

“The results of the Apple Heart Study highlight the potential role that innovative digital technology can play in creating more predictive and preventive health care,” said Lloyd Minor, M.D., dean of the Stanford School of Medicine. “Atrial fibrillation is just the beginning, as this study opens the door to further research into wearable technologies and how they might be used to prevent disease before it strikes—a key goal of Precision Health.”

Breaking New Ground

Through it’s participation in the tests Apple have not only broken new ground in proving the accuracy of such wearable technology in this one small area, but have opened the door to the possibilities of proving the reliability of several more innovations such as the ECG capabilities of the Apple Watch Series 4. Although currently Apple insist that this capability is not meant as a medical tool, as the watch increases it accuracy and dependability we could possibly be seeing the advent of ECG monitoring taking place outside of the hospital environment.

“The performance and accuracy we observed in this study provide important information as we seek to understand the potential impact of wearable technology on the health system,” says Marco Perez, M.D., associate professor of cardiovascular medicine at Stanford. “Further research will help people make more informed health decisions.”

  1. I love Apple watch personally. Even though they are a bit expensive I still like their features and all the benefits they can deliver to human beings. You’re article has explained everything clearly about the apple watch. You pointed out all the key features in it. Thank you so much for sharing this article with us.

    It is so insightful and resourceful.

  2. This Apple heart rate monitor is one of the most interesting advance technology in the phone production industry. This is not recommended most by doctors just because they feel it wilk reduce the rate people come to the check ups and all. I have an uncle that uses on of this heart monitoring wrists apple watch and it is very accurate as this was even confirmed by his doctor. I feel it’s a great piece of tech

    1. Thank you for taking the time to get back to me. I am glad that a family member is taking advantage of the technology.

  3. Thanks for writing this article on the question maybe apple and it cohorts can be trusted. I will say so far apple has been trying there best try innovative technology in all aspects in all there numerous device in health sector like the  Apple Watch that can notify wearers of possible atrial fibrillation and some others.they may not be perfect yet but there is possible more room for improvement 

  4. My father identified a heart problem with his fitbit showing an unusually high heart rate. Imagine the possibilities of this apple watch. 20 years ago we couldn’t have imagined this sort of technology being so common place in our lives. It is incredible to live in this lifetime.

    Thanks for this interesting read Adrian

  5. I really am not a big fan of the Apple I dustry but I can say that they have really done a great job in the technology market and they have every potential to go far than they are now. For me, Apple has been the best when it comes to technology that tells you things about your health.

  6. Just recently, a friend of mine told me that she sells fitness trackers, and I thought it was a laudable achievement in the medical and electronic. 

    This is a synergistic and living saving achievement by the Medical and Electronic world! 

    It is such a convenient, easy and time saving way to save one’s life. I know a few people that have dropped dead, without even knowing they have atrial fibrillation at all. 

    1. Thank you for taking the time to read my article and comment on it. I agree that the more that technology can bring to the health of all of us the better.

  7. As a person who has lived for 80 years,, with a heart that misses a beat occasionally,and having been told by anaesthetists of the fact,I think this idea is good.

    Wearing a watch that monitors your heart, is good for people, who are apprehensive about their condition.

    That the patch, worn to check the watch,showed that the watch is 71% accurate,is impressive, and shows that Apple is producing a good product.

    This breakthrough, opens many areas of future uses, of this technology, in the medical field.

  8. I absolutely love this insightful article because it is full of great information. This is fascinating and interesting to me.Apple has a company did a great job in technology know monitoring the heartbeat. With the there will be reduction in citizen death rate.Can apple watch series 4 be malfunctioning? Great write, best regards
