Supraventricular tachycardia diagnosed by smartphone ECG

Abstract

Diagnosis of paroxysmal supraventricular tachycardia (PSVT) may be difficult due to its episodic nature, which can be brief and self-limited, limiting the ability for clinicians to diagnose the specific rhythm disorder in a timely manner. We present a case of PSVT, which was unable to be diagnosed through typical evaluation with an event monitor despite several years of symptoms. The patient was ultimately diagnosed using the AliveCor Mobile ECG, a smartphone-based ECG device and application, which he purchased himself and captured a typical atrioventricular node re-entrant tachycardia. The patient was then able to email his cardiologist the tracing, which led to an electrophysiology study and successful slow pathway ablation procedure. Smartphone-based technology has the potential to push diagnostic evaluations outside of the healthcare system and empower patients.

Arrhythmia in an athlete diagnosed by smartphone electrocardiogram: a case report

“…The utility of smartphone ECG applications has previously been reported in the general population. 6 Previously, smartphone ECG devices have been used to rule out sinister pathology in athletes presenting with palpitations. 7 This case is novel, however, as there are no known previous reports in the literature where smartphone ECG monitoring has been successfully used to diagnose arrhythmias in a competitive athlete.…”

Assessment of signal quality measured with a smart 12‐lead ECG acquisition T‐shirt

“…The yield of the smart T-shirt to detect and diagnose cardiac arrhythmias in patients also remains to be demonstrated. Other devices have recently been tested to detect frequent arrhythmias such as atrial fibrillation in a large number of patients (Pagola et al, 2018;Tabing et al, 2017;Turakhia et al, 2019;William et al, 2018). However, none of these devices have achieved routine clinical use for the ECG recording.…”

“…During the last years, a number of new devices have been designed and proposed for continuous non-invasive ECG monitoring. A first category of portable devices measures a surrogate of cardiac activity (e.g., pulse rate with photoplethysmography or recorders with inner electrodes) to identify irregular beats as a potential marker of cardiac arrhythmias and then send the information through wireless transmitters such as smartphones (Bruce et al, 2016;Gropler, Dalal, Hare, & Silva, 2018;Tabing, Harrell, Romero, & Francisco, 2017;William et al, 2018). These devices have been demonstrated to provide good quality single-lead ECG signal and have good accuracy to detect pulse irregularities (Taggar, Coleman, Lewis, Heneghan, & Jones, 2016).…”
