“…These findings suggest that the AC may prove a useful tool in the diagnosis of cardiac arrhythmias, and whilst clinical utilization has been investigated in a number of sECG devices, generalisability of results remains unclear. [9][10][11][12][13] Notably, a recent systematic review evaluating detection of arrhythmias beyond AF using smartwatches, as opposed to the AC, described 14 case reports/series and 4 cohort studies which included a spectrum of arrhythmias detected by sECGs, including VT, various SVTs, second-and thirddegree atrioventricular block, Wolff-Parkinson White syndrome, sinus bradycardia and sinus tachycardia. 31 In a study by Mehta et al, when comparing four sECG devices on inpatients and with tracings analysed by a mixed group of clinicians, described differences between sECG device tracings interpretability possibly attributable to inherent differences in hardware and software features.…”

“…[6][7][8] The past decade has witnessed surge in the prevalence and popularity of cardiovascular health devices, including those capable of recording single-lead electrocardiograms (sECG). [9][10][11][12][13] One such device is the AliveCor KardiaMobile ([AC] AliveCor Inc, Mountain View, California, USA), a handheld sECG device has emerged as an alternative option for outpatient arrhythmia investigations. 7,8 While its accuracy for detecting sinus rhythm (SR) and atrial fibrillation (AF) is established against 12-lead ECGs, there is limited data on its accuracy for non-AF arrhythmias, nor for validation against gold standard cardiac electrophysiology studies (EPS).…”

Background Single-lead ECG devices may allow detection and diagnosis of cardiac rhythms. However, data on their accuracy for detecting cardiac arrhythmias beyond atrial fibrillation are limited. Objectives To determine the accuracy of the AliveCor KardiaMobile (AC; AliveCor Inc, Mountain View, CA) for the diagnosis of arrhythmias against gold standard cardiac electrophysiology study (EPS). Methods Patients undergoing clinically indicated EPS underwent simultaneous rhythms recording with an infraclavicular-placed AC, standard 12-lead ECG and EP catheters for intracardiac electrograms. Rhythms recorded during EPS were classified based on electrogram, 12-lead ECG and clinical findings. Blinded reviewers provided differential diagnoses for the single-lead AC tracings; a separate reviewer compared diagnoses made between the AC tracings and EPS findings. Results From 49 patients, 843 cardiac rhythms were captured during 502 AC recordings. Analysis of tracings containing sinus rhythm (n=273) returned overall accuracy of 92%, with sensitivity and specificity values of 93% and 92%, respectively. Accuracy for tracings per rhythm were atrial fibrillation 91% (n=51); supraventricular tachycardia accuracy was 89% (n=191), ventricular tachycardia 91% (n=198), ventricular fibrillation 98% (n=11), asystole 100% (n=5). Accuracy for supraventricular ectopy was 93% (n=28) and premature ventricular complexes was 91% (n=86). Overall accuracy was 94% for uninterrupted rhythms and 93% in tracings from patients with baseline bundle branch block. Conclusions When compared against the gold standard EPS diagnosis, interpretation of arrhythmias recorded by an AliveCor single-lead ECG device had reasonable diagnostic accuracy.

“…Fortunately, advancements in technology have introduced wearable smart devices, such as smartwatches, capable of assisting in the detection and management of cardiac arrhythmias and various health conditions [8,9]. Wearable smart devices have become one of the fastest-growing sectors in the technology industry, with major tech companies like Apple (Apple Watch), Google (Fitbit), and Samsung (Galaxy) developing smartwatches capable of monitoring biometric data, including heart rhythm, pulse rate, oxygen saturation, blood pressure, and sleep pattern [10].…”

“…Beyond detecting AF, smartwatches can prove valuable in identifying other ECG abnormalities, such as bradyarrhythmias, tachyarrhythmias, or deviations indicative of ischemia [14]. With their current capabilities, smartwatches can provide excellent support for healthcare professionals in recognizing and managing various ECG abnormalities [8].…”

Smartwatches represent one of the most widely adopted technological innovations among wearable devices. Their evolution has equipped them with an increasing array of features, including the capability to record an electrocardiogram. This functionality allows users to detect potential arrhythmias, enabling prompt intervention or monitoring of existing arrhythmias, such as atrial fibrillation. In our research, we aimed to compile case reports, case series, and cohort studies from the Web of Science, PubMed, Scopus, and Embase databases published until 1 August 2023. The search employed keywords such as “Smart Watch”, “Apple Watch”, “Samsung Gear”, “Samsung Galaxy Watch”, “Google Pixel Watch”, “Fitbit”, “Huawei Watch”, “Withings”, “Garmin”, “Atrial Fibrillation”, “Supraventricular Tachycardia”, “Cardiac Arrhythmia”, “Ventricular Tachycardia”, “Atrioventricular Nodal Reentrant Tachycardia”, “Atrioventricular Reentrant Tachycardia”, “Heart Block”, “Atrial Flutter”, “Ectopic Atrial Tachycardia”, and “Bradyarrhythmia.” We obtained a total of 758 results, from which we selected 57 articles, including 33 case reports and case series, as well as 24 cohort studies. Most of the scientific works focused on atrial fibrillation, which is often detected using Apple Watches. Nevertheless, we also included articles investigating arrhythmias with the potential for circulatory collapse without immediate intervention. This systematic literature review provides a comprehensive overview of the current state of research on arrhythmia detection using smartwatches. Through further research, it may be possible to develop a care protocol that integrates arrhythmias recorded by smartwatches, allowing for timely access to appropriate medical care for patients. Additionally, continuous monitoring of existing arrhythmias using smartwatches could facilitate the assessment of the effectiveness of prescribed therapies.
