A randomized comparison of His bundle pacing versus right ventricular pacing: Effect on left ventricular function and biomarkers of collagen metabolism
(2023)
BACKGROUND: Right ventricular pacing (RVP) can result in pacing-induced cardiomyopathy (PICM). It is unknown whether specific biomarkers reflect differences between His bundle pacing (HBP) and RVP and predict a decrease ...
T-wave inversions during conduction system pacing: A marker of more physiological ventricular activation
(2022)
Permanent myocardial pacing can preserve adequate heart rates and improve symptoms and mortality in patients with bradycardia. Conventional right ventricular (RV) pacing is far from the optimal treatment since up to 20% ...
Left ventricular resynchronization with left bundle branch area pacing: does the type of capture matter?
(2023)
Cardiac resynchronization therapy (CRT) with biventricular pacing (BiV) has been a mainstream treatment in heart failure patients with wide QRS complexes for two decades. In recent years, left bundle branch pacing (LBBP) ...
Left ventricular septal pacing - can we trust the ECG?
(2023)
In contrast to left bundle branch pacing, the criteria for left ventricular septal pacing (LVSP) were never validated. LVSP is usually defined as deep septal deployment of the pacing lead with a pseudo-right bundle branch ...
Resynchronization for shifting conduction patterns - When a coronary sinus lead is not enough
(2023)
A 60-year-old patient with heart failure (NYHA II) due to non-ischemic cardiomyopathy with a left ventricular end-diastolic diameter (LVEDD) of 73 mm and left ventricular ejection fraction (LVEF) 20% presented with ...
Is it a true left bundle branch block or not?
(2023)
Among patients with wide QRS complexes of nonRBBB morphologies on ECG, there are those with preserved left septal Purkinje activation, i.e., intraventricular conduction delay (IVCD). Unfortunately, twelve lead ECGs do not ...
Bipolar anodal septal pacing with direct LBB capture preserves physiological ventricular activation better than unipolar left bundle branch pacing
(2023)
BACKGROUND: Left bundle branch pacing (LBBP) produces delayed, unphysiological activation of the right ventricle. Using ultra-high-frequency electrocardiography (UHF-ECG), we explored how bipolar anodal septal pacing with ...
