A study on stability analysis of atrial repolarization variability using ARX model in sinus rhythm and atrial tachycardia ECGs [PDF]

, 2016
© 2016 Elsevier Ireland Ltd Background The interaction between the PTa and PP interval dynamics from the surface ECG is seldom explained. Mathematical modeling of these intervals is of interest in finding the relationship between the heart rate and ...

Multiple Catheter Recording in Horses to Investigate Atrial Depolarization Pattern During Sinus Rhythm and Induced Premature Atrial Complexes [PDF]

Journal of Veterinary Internal Medicine
Background Detailed characterization of arrhythmias can be performed by multiple catheter mapping; but this has not yet been explored in horses. Objectives Perform ultrasound‐guided multiple catheter mapping of the right heart during sinus rhythm and ...

Impact of digoxin on sinus rhythm restoration after catheter ablation of persistent atrial fibrillation and drug-refractory atrial tachyarrhythmia recurrence: A cohort study [PDF]

Journal of International Medical Research
Objective Early rhythm control has demonstrated clinical benefits even among patients with persistent atrial fibrillation. However, some patients continue to experience recurrent atrial tachyarrhythmias despite undergoing catheter ablation and treatment ...

Thromboembolic trapping and anticoagulation dilemma in a patient with heart failure and reduced ejection fraction in sinus rhythm: A case report [PDF]

Radiology Case Reports
Severe left ventricular dysfunction and ventricular wall motion abnormalities predispose individuals to thrombosis and thromboembolism. Thromboembolism is one of the main causes of increased mortality in patients with heart failure and reduced ejection ...

Absent fourth heart sound as a marker of adverse events in hypertrophic cardiomyopathy with sinus rhythm

Annals of Noninvasive Electrocardiology, 2022
Background Patients with hypertrophic cardiomyopathy (HCM) in sinus rhythm commonly show the fourth heart sound (S4). The lack of S4 may be a marker of impaired atrial function in HCM patients with sinus rhythm.

Atrial fibrillation, electroconvulsive therapy, stroke risk, and anticoagulation

The Egyptian Heart Journal, 2023
Background Electroconvulsive therapy (ECT) is a therapy used to treat refractory mental health conditions, ranging from depression to catatonia, and it has gained renewed prominence in practice and the literature of late.

Left atrial mechanical remodelling assessed as the velocity of left atrium appendage wall motion during atrial fibrillation is associated with maintenance of sinus rhythm after electrical cardioversion in patients with persistent atrial fibrillation.

PLoS ONE, 2020
The velocity of left atrium appendage (LAA) wall motion during atrial fibrillation (AF) is a potential marker of mechanical remodelling. In this study, we investigated whether the velocity of LAA wall motion during AF predicted the success of electrical ...

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

Role of clonidine in perioperative acute atrial fibrillation

Saudi Journal of Anaesthesia, 2011
We report a case of acute onset atrial fibrillation (AF) that presented for emergency surgery where rate control and sinus rhythm were successfully achieved using clonidine. Patient had acute AF with high blood pressure. Metoprolol failed to decrease the
