An open‐label, single‐arm, dose‐escalating concentration–QT study to investigate the cardiac effects and safety of paroxetine in healthy adults

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Paroxetine is a selective serotonin reuptake inhibitor (SSRI), approved for treatment of major depressive disorder and anxiety disorders. Some SSRIs are known to prolong the QT interval; however, clinical evidence to establish a lack of association between paroxetine and corrected QT interval (QTc) prolongation is limited. Therefore, this

M-mode Diagnosis of Tachyarrhythmia Can be Erroneous Owing to “Pseudo 1:1 Atrioventricular Movement” of the Atrial Wall Adjacent to the Atrioventricular Valve Possibly due to Atrioventricular Constraint: A Case of Neonatal Atrial Flutter With 2:1 Atrioventricular Conduction

Clinical Medicine Insights: Cardiology, 2018
M-mode echocardiography has been playing an important role in the diagnosis of fetal tachyarrhythmia. We recently encountered a neonatal case of atrial flutter with 2:1 atrioventricular conduction.

Reliability of Early Fetal Echocardiography for Congenital Heart Disease Detection: A Preliminary Experience and Outcome Analysis of 102 Fetuses to Demonstrate the Value of a Clinical Flow-Chart Designed for At-Risk Pregnancy Management [PDF]

, 2016
Early fetal echocardiography (EFEC) is a fetal cardiac ultrasound analysis performed between the 12th and 16th week of pregnancy (compared with the usual 18-22 weeks).

Early clinical pharmacology evaluation of the novel anti‐inflammatory macrolide, glasmacinal (EP395): tolerability, pharmacokinetics and drug interactions

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims This work assessed the pharmacokinetics (PK), safety and tolerability of glasmacinal (EP395, an oral anti‐inflammatory macrolide with negligible antimicrobial activity in development for COPD treatment) in two healthy participant trials: ‘first‐in‐human’ (FIH) and ‘drug–drug‐interaction’ (DDI).

Transient 2:1 Atrioventricular Block with Peri-Conduction System Pacing After Leadless Pacemaker Implantation [PDF]

Texas Heart Institute Journal
This report discusses a case of transient 2:1 atrioventricular block with conduction system pacing 4 hours after leadless right ventricular pacemaker implantation in a 19-year-old patient with a history of cardioinhibitory syncope and asystole cardiac ...

Implantation of atrioventricular synchronous and atrioventricular universal pacemakers

The Journal of Thoracic and Cardiovascular Surgery, 1983
Implantation of pacemakers which sense in the atrium and the ventricle requires understanding of both antegrade conduction, from the atrium to the ventricle, and retrograde conduction, from the ventricle to the atrium. Of 53 patients undergoing pacemaker implantation, 25 (47%) had retained VA conduction and 25% of those with complete heart block had 1 ...

Automatic Mode Switching in Atrial Fibrillation [PDF]

, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM
