At a time where the electronic devices are getting smarter than the human minds, here is an advantage that can save lives. The smart devices are not confined to the Smartphones or the computers. It’s been some time the watches have become smarter but it was not as popular as it is right now. The factor that made it this popular is its ability in tracking the health.

Fondly known as fitness watches, these watches can track the steps that you walk and calculate it to measure the calories you burn. This is just the beginning of the many things these devices can do. Among them is the possible prediction of heart attacks risk. Can the likes of the smartwatches and other health tracker devices really warn you of any impending heart attacks?

What The Health Trackers Can Track?

The health trackers usually monitor the exercise patterns, calorie utilization, sleep, and other activities etc. As the technology improved, there are other uses of the smart devices where they are user-friendly, wearable, and most importantly, ability to sync with the smart applications. The smart applications provide the analysis and other settings to make these health devices more users friendly and attractive in use.

Smartphones itself, wearable health devices and the smartwatches are the popular ones. The most sorted after among these is the smartwatches that show the time and the activities. It can stay closer to the body and easily manageable.

As the popularity chart shot up, more and more facilities were added to them. The most recent and significant one added here is the heartbeat tracking that is useful for the prediction of the possible heart attacks.

Health Trackers And Heart Health

Most health trackers measure the exercise, steps, run etc. All of these are taken into consideration in tracking the changes inside the body. The newest health trackers have also come up with heart beat monitoring. The special sensors attached to these devices can track the rest time heartbeat as well as the same when the body is doing any activity.

The significance of the heart monitoring is that it can detect the sharp or sudden changes in the resting heartbeat and deduce it to be abnormal. As the devices get smarter, more features are present in them.

The Effectiveness Of Health Trackers

Health trackers monitor the activity levels and take the values into the calculation. The effectiveness of these readings is high as long as the user wears it 24×7. Using these devices on and off can show only the average of the readings, which may not be as accurate as it would, when it is worn day and night.

The sensors can detect the changes in heart rhythm and can alert the user when there is a major change. If the user is unable to respond as needed within the stipulated time span, the alert is transferred to the near ones and the medical team set for the action.

Though these health trackers can be effective, it is not the ultimate solution for the prevention of faster action for heart attacks. Neither is it definitely a heart attack. The readings are mostly 90% accurate since there can be time and data variables and inconsistent.

Heart Rhythm And Arterial Problems

Most of these health trackers track the rhythm of the heart. The actual cause for heart attacks may be more related to the arteries rather than the rhythm itself. The rhythm is just a small window opened to the heart health. At the same time, one cannot completely rule out these trackers.

These trackers would also not give the complete information needed by the medical professionals to take the decisions needed. But it definitely saves them time by getting some of the information right away.

The accuracy of these devices is the question because the biological changes are different in each individual and the changes that lead to a heart attack are also different. That is the main reason why the health trackers may NOT be able to warn you of a heart attack risk.

Who Can Benefit From These Health Trackers?

People who have irregular heartbeat can benefit the most out of these devices. These devices can help them track their heart performance, even if there are discrepancies in the readings. It saves them time from going for frequent checkups and is a lot easier to have them with them.

The app that the most such devices connect to, provides the daily, weekly and monthly analysis that the users can show their doctor’s and help in the further assessment.

The Safety Of Health Trackers And Heart Health

One question that has bothered many of the users is if it causes any other health hazard, especially for the heart. Since these devices are wearable and have sensors, these might have some kind of effect on the health. But the makers of these devices give thumbs up to them unless the users have any devices inside the heart.

This doubt is important as these tracking devices are meant to be used the whole day, even while you sleep. Since they do emit some waves and radiation, the ill effects could be a possibility. Unfortunately, there is no clear evidence of the safety of these devices. At the least, they are safe as your carrying the cell phones.


There is no definite technology that can predict a heart attack with 100% accuracy. Nor is it possible for the wearable health trackers to do the same. All they can do is to read the data, analyze the data it reads. It is up to the humans to assess this data and come up with possible scenarios of changes that may or may not cause a heart attack in the time to come. It definitely would not give an answer straight away.
