The Future Of Cardiac Monitoring: Exploring Wearable Health Devices
Cardiac disease and its associated complications are one of the leading causes of death worldwide. Unfortunately, most individuals do not realize they have a heart problem until it is too late. The use of wearable health devices has increased significantly over the past few years, proving to be useful in detecting health issues early on. As cardiac monitoring becomes more advanced, devices that were once only seen in hospitals are now being replaced with innovative and portable wearable devices. The future of cardiac monitoring is embracing technological advancements in healthcare to improve patient outcomes and promote a healthier lifestyle.

What are Wearable Health Devices?

Wearable health devices are wearable technology devices that are designed to collect health-related data. These devices are usually worn on the wrist like a watch or a band, and they can collect heart rate, blood pressure, calorie consumption, respiration rate, and sleep data. Wearable health devices have become increasingly popular in recent years, especially among fitness enthusiasts who want to monitor their physical activity levels. As wearable health devices continue to evolve, they are becoming more sophisticated in collecting health data. Recently, wearable health devices have started to incorporate more cardiac monitoring features, marking a significant milestone in the field of cardiac healthcare.

How Do Wearable Health Devices Monitor Heart Health?

Wearable health devices monitor heart health in a variety of ways. Most devices come equipped with a heart rate monitor, which tracks your heart rate in real-time and provides instantaneous feedback. Some devices also have an electrocardiogram (ECG) feature. An ECG measures the electrical activity of the heart and can detect any irregularities in the heart’s rhythm. For individuals at high risk of developing cardiac diseases, such as atrial fibrillation, a wearable ECG monitor can be a useful tool for detecting such abnormalities early on.There has also been a trend of wearable health devices incorporating optical sensors that analyze blood flow through the skin, which can estimate blood pressure. This is achieved through measuring the pulse transit time (PTT), which is the time taken for the blood pressure wave to travel the distance between two arterial sites. These wearable devices estimate blood pressure by analyzing the PTT, ensuring the wearer can have access to cardiac monitoring on an ongoing basis.

Current Challenges and Limitations of Wearable Health Devices

Despite the rapidly growing popularity of wearable health devices, there are still some challenges and limitations that must be addressed. For one, many wearable health devices are not yet approved by regulatory bodies such as the FDA, meaning their accuracy and reliability may not be guaranteed. Additionally, wearable devices may not be suitable for everyone. For example, people with skin allergies or sensitivities may struggle with wearing devices that need to be in contact with their skin. The battery life of some wearable health devices may also be considered short, making it necessary for frequent recharging. While these challenges exist, there are continuously improvements being made in technology to help combat these limitations.

Future of Cardiac Monitoring With Wearable Health Devices

With advancements in technology, wearable health devices are becoming smaller, less invasive, and more accurate. Future iterations of these devices will enable better and more frequent monitoring of cardiac health for individuals that are predisposed to cardiac diseases or those who have already been diagnosed. Such devices will enable early detection of a range of cardiac issues, such as atrial fibrillation, arrhythmia, and heart attacks. By incorporating machine learning and artificial intelligence into these devices, more accurate and personalized diagnostic features will be incorporated. These devices will be able to collect and analyze extensive data and provide real-time results. This is especially useful in situations where individuals are unaware that they may be at risk of heart diseases and need to take preventative measures before a disastrous situation develops.

Examples of Wearable Health Devices for Cardiac Monitoring

Let’s take a look at some of the most notable wearable health devices available today that focus on cardiac monitoring.

Apple Watch

The Apple Watch has ECG capabilities that allow wearers to take an electrocardiogram by merely placing their finger on the digital crown. The device can analyze the waveform and provide instant feedback, indicating if atrial fibrillation is detected.

AliveCor KardiaMobile

AliveCor KardiaMobile is a portable ECG monitor that can be attached to the back of a smartphone or tablet. The device records a 30-second ECG and reports the results directly to a physician.

Biosense Webster Contactless Monitoring

The Biosense Webster iTClamp is a product from Johnson & Johnson that monitors blood flow through the ear. This innovative, minimally invasive product enables cardiac monitoring without the need for an EKG or blood testing.


Wearable health devices are revolutionizing the way we monitor cardiac health. With their increasing sophistication and accessibility, they are becoming more useful tools for detecting and monitoring potential cardiac issues. While there may still be challenges and limitations to overcome, the use of wearable health devices for cardiac monitoring is a rapidly growing trend that will continue to evolve in the future.Incorporating cardiac monitoring into wearable health devices creates opportunities to detect abnormalities early on, providing more extended preventative care and ultimately saving lives. As wearable health devices become more accurate and more reliable, we hope to see their utilization in cardiac healthcare increase exponentially. They are paving the way for increased collaboration in healthcare as medical professionals, caregivers, and patients leverage this technology to improve health outcomes.
