Cardiac arrhythmias are one of the leading causes of morbidity and mortality worldwide, making timely detection critical for patient outcomes. Wearable technology, equipped with advanced sensors and artificial intelligence (AI) algorithms, has become a promising tool for the continuous monitoring and automated detection of arrhythmias. This paper explores the current advancements in wearable technology for arrhythmia detection, focusing on its accuracy, clinical applications, and potential to transform cardiac care. We will also address challenges such as data privacy, integration with healthcare systems, and future trends in this rapidly evolving field.
