Electrocardiographic Predictors of Cardiac Reverse Remodeling After Left Bundle Branch Area Pacing in Atrioventricular Block: Emphasis on Post‐Pacing QRS Duration

Journal of Arrhythmia
Background and Aim Permanent pacing is essential for atrioventricular block, but conventional right ventricular pacing may cause electrical dyssynchrony and ventricular dysfunction. LBBAP offers a more physiological alternative, although response varies.

Automatic diagnosis of strict left bundle branch block using a wavelet-based approach.

PLoS ONE, 2019
Patients with left bundle branch block (LBBB) are known to have a good clinical response to cardiac resynchronization therapy. However, the high number of false positive diagnosis obtained with the conventional LBBB criteria limits the effectiveness of ...

Correlation of QRS duration with myocardial blush grade as a marker of myocardial reperfusion in primary percutaneous coronary intervention

Indian Heart Journal, 2018
Background: The association between duration of QRS and myocardial reperfusion is not very well established. Our aim was to assess the relationship between measurements of QRS duration and myocardial blush grade (MBG) in patients with ST-elevation ...

Biventricular paced QRS area predicts acute hemodynamic CRT response better than QRS duration or QRS amplitudes

, 2017
Introduction: Vectorcardiographic (VCG) QRS area of left bundle branch block (LBBB) predicts acute hemodynamic response in cardiac resynchronization therapy (CRT) patients. We hypothesized that changes in QRS area occurring with biventricular pacing (BV)

Clinical applications of wearable devices for individuals with at‐risk substance use and substance use disorders: A systematic review

The American Journal on Addictions, EarlyView.
Abstract Background and Objectives Managing substance use disorders (SUDs) is limited by the lack of longitudinal clinical data during active use and recovery. Wearable devices may help address this gap by capturing physiological and behavioral data in real‐world settings.

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Aspects of Left Ventricular Morphology Outperform Left Ventricular Mass for Prediction of QRS Duration

, 2010
Methods: The study population of healthy adult volunteers was divided into a sample for development of a prediction model (n = 63) and a testing sample (n = 30).

Refining the treatment of immune checkpoint inhibitor–associated myocarditis: Challenges, innovations and rechallenge considerations

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitor (ICI)‐associated myocarditis has emerged as a severe and clinically complex immune‐related toxicity that poses significant challenges for therapeutic decision‐making in routine cardio‐oncological care. High‐dose corticosteroids remain the first‐line therapy, yet their timing, dosage and tapering require careful clinical ...

New method for measuring QRS duration using high-frequency electrocardiography

, 1982
Definition of QRS onset and offset is a basic problem in electrocardiography. Current techniques rely either on subjective estimates or on computer algorithms using QRS derivative or spatial vector velocity parameters.

Immune checkpoint inhibitor‐induced arrhythmias: Mechanistic insights from clinical and preclinical studies

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitors (ICIs) have transformed cancer therapy, but their efficacy continues to be limited by immune‐related adverse events. Among these, ICI‐induced cardiac arrhythmias are increasingly recognised as a major adverse reaction, encompassing a broad spectrum of clinical phenotypes, including conduction blocks, atrial fibrillation and
