“…Although a large proportion of the research has investigated the use of mobile apps to detect AF, other arrhythmias have been investigated. A study presented in abstract in 2016 by Dimarco et al [86] used the AliveCor device to investigate 148 patients who had reported palpitations for arrhythmias. The device was used as an alternative to ambulatory monitoring.…”

Background Mobile phone apps capable of monitoring arrhythmias and heart rate (HR) are increasingly used for screening, diagnosis, and monitoring of HR and rhythm disorders such as atrial fibrillation (AF). These apps involve either the use of (1) photoplethysmographic recording or (2) a handheld external electrocardiographic recording device attached to the mobile phone or wristband. Objective This review seeks to explore the current state of mobile phone apps in cardiac rhythmology while highlighting shortcomings for further research. Methods We conducted a narrative review of the use of mobile phone devices by searching PubMed and EMBASE from their inception to October 2018. Potentially relevant papers were then compared against a checklist for relevance and reviewed independently for inclusion, with focus on 4 allocated topics of (1) mobile phone monitoring, (2) AF, (3) HR, and (4) HR variability (HRV). Results The findings of this narrative review suggest that there is a role for mobile phone apps in the diagnosis, monitoring, and screening for arrhythmias and HR. Photoplethysmography and handheld electrocardiograph recorders are the 2 main techniques adopted in monitoring HR, HRV, and AF. Conclusions A number of studies have demonstrated high accuracy of a number of different mobile devices for the detection of AF. However, further studies are warranted to validate their use for large scale AF screening.

“…71,74,75 In addition to AF screening, these devices have been evaluated for AF symptom-validation, AF recurrence after cardioversions, cardiac surgery or ablations, and as a direct continuation of OAC therapy. [76][77][78][79][80] The advantages of portable single-lead ECG devices are their small size, ease of use, and direct access to AF diagnosis through the device's ECG recording. However, asymptomatic and/or paroxysmal AF may go undetected with these patient-triggered mHealth devices and singlelead ECG recording may sometimes be of insufficient quality for AF diagnosis.…”

Atrial fibrillation (AF) is globally the most common arrhythmia associated with significant morbidity and mortality. It impairs the quality of the patient's life, imposing a remarkable burden on public health, and the healthcare budget. The detection of AF is important in the decision to initiate anticoagulation therapy to prevent thromboembolic events. Nonetheless, AF detection is still a major clinical challenge as AF is often paroxysmal and asymptomatic. AF screening recommendations include opportunistic or systematic screening in patients ≥65 years of age or in those individuals with other characteristics pointing to an increased risk of stroke. The popularities of well-being and taking personal responsibility for one's own health are reflected in the continuous development and growth of mobile health technologies. These novel mobile health technologies could provide a cost-effective solution for AF screening and an additional opportunity to detect AF, particularly its paroxysmal and asymptomatic forms.

“…5,6 However, the transient nature of arrhythmias and symptoms may limit the diagnostic yield of ambulatory monitoring, which is reported to be as low as 15% for patients with unresolved palpitations. [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.…”

“…[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). [14][15][16][17] We therefore aimed to determine the accuracy of the AC in diagnosing a variety of arrhythmias against the gold standard cardiac EPS, through comparison of blinded AC interpretations to "gold standard" diagnoses derived from intracardiac electrograms (EGMs) and a 12-lead ECG during a clinically indicated 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.
