Wearable cardiovascular devices have emerged as essential tools for continuous heart rate monitoring. Especially for the early detection and management of heart related conditions. This article explores the advancements and functionalities of four categories of the wearable heart monitoring products like, smart patches, in – ear heart monitoring devices, smartwatches and smart rings. The smart patches offer clinical grade heart rhythm data with mobility, allowing real- time analysis without hospital equipment. In- ear monitors, utilizing photoplethysmography (PPG) sensors, provide accurate readings from the ear canal due to its rich blood supply. Smartwatches combine multi sensor capabilities, including heart rate, blood oxygen levels, and ECG, with smartphone integration for user friendly health tracking. Smart rings, the most discreet among them, prioritize minimalism while offering essential metrics like heart rate variability (HRV), sleep, and activity data. These technologies collectively push the boundaries of personalized healthcare, providing accessible, real time cardiovascular monitoring.
