INTRODUCTION

Cardiac arrhythmias, which manifest as irregularities in heart rhythm, are associated with an extensive array of etiological factors including congenital, structural, immunological, physical, metabolic, and infectious diseases[1]. Based on diagnosed cases in the general population, they exhibit a prevalence of 1.5% to 5%, with atrial fibrillation emerging as the predominant variant[2]. Arrhythmias can be asymptomatic or symptomatic and often present in a paroxysmal fashion, which complicates the accurate estimation of their true prevalence. The diagnostic process for arrhythmias is challenging due to the variable clinical presentations and episodic symptom manifestation, demanding a range of management approaches tailored to specific patient conditions[3].

Traditional methods, such as short-term recordings from standard electrocardiography (ECG) and prolonged Holter monitoring, often fail to capture intermittent arrhythmias and limit continuous, real-time cardiac assessment[4]. Recent advances in wearable technology have completely changed several facets of healthcare. With sensors and cutting-edge algorithms, wearable technology has the potential to greatly improve the early diagnosis, monitoring, and treatment of cardiac arrhythmias, leading to better patient outcomes[5]. The development of effective and efficient detection and management techniques has become crucial due to the increasing frequency of cardiac arrhythmias and the accompanying morbidity and death. By offering continuous, non-invasive monitoring of heart rhythms and enabling real-time feedback and action, wearable technology presents a possible option. Wearable technologies can detect arrhythmias early, helping prevent life-threatening consequences through prompt therapies and by empowering patients to actively engage in their care[6,7].

The accuracy and dependability of these devices have substantially increased due to development of sensor technology, signal processing algorithms, and data analytics, enabling accurate arrhythmia detection and categorization[8,9]. Real-time data transmission to healthcare experts has been made possible by the integration of wearable technology with telemedicine platforms and remote monitoring (RM) systems. This has allowed for prompt interventions and individualized treatment programs[8,10].

In recent years, RM has gained prominence, especially in the field of cardiac arrhythmias. In cardiac arrhythmias, RM leverages advanced technologies to manage patients with cardiac implantable electronic devices, enhancing care delivery[11]. Over the past decade, RM has evolved from basic transtelephonic monitoring to sophisticated systems capable of continuous, wireless data transmission, actively alerting healthcare providers to critical changes in patient status. This innovation allows for earlier diagnosis and intervention, reducing hospital visits and improving survival rates[12]. RM is particularly beneficial during constraints like the coronavirus disease 2019 pandemic, as it supports remote care and reduces healthcare costs while expanding access, especially in underserved areas[11,12]. RM's efficiency and safety promise broader applications in managing chronic conditions[13].

EXPLORATION OF WEARABLE TECHNOLOGIES IN HEALTH CARE

Wearable technology encompasses electronic devices designed to be worn on the body, often embedded within clothing or accessories, facilitating the collection and transmission of physiological data[14]. These devices are equipped with advanced sensors to monitor and document a variety of health metrics[15]. Examples of wearable technology include smartwatches, fitness bands, subcutaneous implants, and chest straps, as summarized and described in Table 1. A predominant method for detecting cardiac arrhythmias involves ECG monitoring, wherein wearable devices with integrated ECG sensors utilize electrodes to continuously monitor heart rhythms and promptly identify any abnormal patterns[16,17]. Additionally, photoplethysmography (PPG) monitoring represents an innovative approach, employing optical sensors to detect changes in blood volume, thereby providing insights into heart rate and rhythm irregularities[18]. Wearable devices equipped with PPG sensors offer a non-invasive solution for arrhythmia detection. Furthermore, while not traditionally wearable, Implantable Loop Recorders (ILRs) are small devices implanted under the skin that continuously monitor heart rhythms, capturing sporadic arrhythmias and enhancing the understanding of a patient's cardiac health[19]. However, motion artifacts can affect signal quality and increase the false-positive rate, while a low signal-to-noise ratio can lead to missed diagnoses.

The degree of accuracy of wearable technology is primarily determined by its sensitivity and specificity in identifying cardiac arrhythmias. High specificity guarantees precise identification of those without arrhythmias, while high sensitivity guarantees correct identification of those with them. Nazarian et al[20] demonstrated that the overall sensitivity, specificity, and accuracy of smartwatches in identifying cardiac arrhythmias were 100%, 95%, and 97%, respectively. These values vary depending on device, patient demographics, and arrhythmia subtype. Smart wearables have been beneficial in remote cardiovascular disease screening and diagnosis, including arrhythmias[21]. Multiple studies have contrasted the outcomes of wearable technology, such as ECG or PPG sensor-equipped devices, with industry-recognized diagnostic methods, such as traditional ECGs. These studies have shown a high degree of concordance, demonstrating that wearable technology can enable accurate and reliable detection of cardiac arrhythmias[22,23].

ILRs are invasive techniques that accurately and reliably capture infrequent arrhythmia episodes over long periods of time, making them appropriate for chronic arrhythmias[19]. PPG and ECG wearable devices offer non-invasive, straightforward options with high accuracy. The continuous or sporadic monitoring offered by PPG and ECG devices enables event-based recording and short-term tracking[24].
