Background Cardiac resynchronization therapy (CRT) is an established for patients with cardiomyopathy, left bundle branch block, and heart failure. His pacing (HBP) may also improve clinical outcomes by narrowing QRS duration. The HBP not always be optimal. aim of the study was to determine if CRT could optimized sequential followed ventricular (LV) (His-Optimized [HOT-CRT]) maximize electrical resynchronization. Methods We attempted permanent in 27 (left block 17, intraventricular...

Abstract Aims A novel therapy offering cardiac resynchronization (CRT) with an additional lead placed in His bundle has been reported a few case reports and series as improving the hemodynamical clinical condition of patients permanent atrial fibrillation (AF) whom other therapeutic methods have not successful. Methods Fourteen consecutive AF, heart failure (HF), branch block (BBB) QRS complex width >130 ms, impaired left ventricular ejection fraction (LVEF) underwent implantation...

Background: The physiological activation of the left atrium (LA) happens through Bachmann bundle, which is crucial for heart's proper functioning. Bayes de Luna first described interatrial blocks (IABs) in 1979, noting their disruption atrioventricular (AV) synchrony. This study aims to evaluate LA mechanics by analyzing strain cases normal and impaired conduction, focusing on retrograde flow pulmonary veins (PV). Methods: included 51 patients who tested positive SARS-CoV-2 exhibited related...

Background: Permanent atrial fibrillation (AF) frequently coexists with heart failure (HF), leading to structural remodeling and progressive sinus node dysfunction. As the condition advances, bradyarrhythmia or tachy-brady syndrome may develop. Right ventricular pacing cardiac resynchronization therapy impair left function due non-physiological activation. His bundle (HBP) offers a more physiological alternative. This study evaluates HBP’s impact on in patients permanent AF. Methods: A...

AimsThe electrocardiographic (ECG) characteristics of atrioventricular (AV) block during reflex syncope may be unique due to the presence hypervagotonia. The aim present study was define ECG AV induced by neurocardiogenic provoked tilt testing (TT).

Anxiety is an emotion, which stimulates sympathetic nervous outflow potentially facilitating vasovagal reflex syncope (VVS) but reports on anxiety levels in patients with VVS are sparse. We studied young women (21–40 years) referred for unexplained transient loss of consciousness (TLOC), and age-matched female controls or without past history TLOC (≈probable VVS). Referred underwent head-up tilt (HUT) according to current ESC Guidelines. State Trait Inventory questionnaire evaluated plus a...
