Wearable technology, including smartwatches and ECG patches, demonstrates significant potential for continuous cardiac monitoring and arrhythmia detection, though challenges remain regarding accuracy, data privacy, and clinical integration.
Wearable devices offer a promising, accessible alternative for continuous cardiovascular monitoring with diagnostic accuracy comparable to traditional methods, though further refinement is needed to address technical and privacy challenges.
As the use of wearable devices continues to expand, their integration into various aspects of healthcare becomes increasingly prevalent. Indeed, significant advancements have been made in the field of cardiology through the application of wearable technology to monitor heart rate, rhythm, and other biological signals. This review examines the various applications of wearable technology in cardiology, with the goal of improving patient care. We evaluate the accuracy and functionality of existing wearable electrocardiograms, defibrillators, blood pressure monitors, fitness trackers, activity trackers, and sleep trackers, including their roles in cardiac rehabilitation. Furthermore, we highlight the significant advancements in wearable electrocardiograms, demonstrating their accuracy comparable to that of traditional monitoring devices, as shown by studies such as the Apple Heart Study and the Fitbit Heart Study. Recent research suggests that wearable electrocardiograms are comparable to conventional monitoring devices in terms of performance and can help reduce healthcare costs. However, as technological improvements continue to evolve, challenges related to accessibility, patient privacy, and the need for improved accuracy are also emerging. This review highlights recent advancements that aim to address these challenges. Nonetheless, further research is crucial to critically assess and identify shortcomings, as wearable devices possess significant potential to enhance cardiovascular and overall health.
Jena et al. (2025) conducted a review in Cardiovascular disease and arrhythmias. Wearable technology (ECG monitors, smartwatches, fitness trackers, wearable defibrillators) vs. Traditional monitoring devices was evaluated. Wearable technology, including smartwatches and ECG patches, demonstrates significant potential for continuous cardiac monitoring and arrhythmia detection, though challenges remain regarding accuracy, data privacy, and clinical integration.
