Can smartphone wireless ECGs be used to accurately assess ECG intervals in pediatrics? A comparison of mobile health monitoring to standard 12-lead ECG [PDF]

, 2018
BACKGROUND:Arrhythmias in children are often paroxysmal, complicating the ability to capture the abnormal rhythm on routine ECG during an outpatient visit. The Alivecor Kardia Mobile (KM) device is a wireless mobile health (mHealth) device that generates

Atrial Imaging and Cardiac Rhythm in Cryptogenic Embolic Stroke: The ARIES Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Unknown cardioembolic sources are frequent causes of cryptogenic stroke. We analyzed the risk of atrial fibrillation (AF) or high burden of ectopic atrial activity (HBEA) in patients with cryptogenic stroke, assessing atrial function and 1 ...

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Computerized electrocardiogram data transformation enables effective algorithmic differentiation of wide QRS complex tachycardias

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Accurate automatic wide QRS complex tachycardia (WCT) differentiation may be accomplished through the use of novel parameters derived from computerized data of the (i) WCT electrocardiogram (ECG) alone and (ii) paired WCT and baseline ECGs. Once automated WCT differentiation models are integrated into commercially available computerized ECG ...

Method to Annotate Arrhythmias by Deep Network [PDF]

, 2018
This study targets to automatically annotate on arrhythmia by deep network. The investigated types include sinus rhythm, asystole (Asys), supraventricular tachycardia (Tachy), ventricular flutter or fibrillation (VF/VFL), ventricular tachycardia (VT).

A novel approach for the diagnosis of ventricular tachycardia based on phase space reconstruction of ECG [PDF]

International Journal of Cardiology, Volume 172, Issue 1, March 2014, Pages e31-e33, 2014
Ventricular arrhythmias comprise a group of disorders which manifest clinically in a variety of ways from ventricular premature beats (VPB) and no sustained ventricular tachycardia (in healthy subjects) to sudden cardiac death due to ventricular tachyarrhythmia in patients with and/or without structural heart disease.

Acupuncture Treatment of a Patient with Bradycardia and Idioventricular Rhythm

Journal of Acupuncture & Meridian Studies, 2022
A patient with bradycardia and an idioventricular rhythm was observed. According to cardiologists, there is no reliable drug treatment for bradycardia with an idioventricular rhythm; instead, the sole treatment is a pacemaker. In the course of this case,
