Left bundle fascicular versus left bundle trunk pacing: A comparison of their electrical synchrony parameters

Indian Pacing and Electrophysiology Journal
Background: Variation in human left bundle branch (LBB) anatomy has a significant effect on the sequence of left ventricular depolarization. However, little is known regarding the electrophysiological characteristics of pacing different LBB fascicles ...

Left Ventricular Pacing In Patients With Congestive Heart Failure [PDF]

, 2006
Cardiac resynchronisation therapy (CRT) using biventricular (BIV) pacing has proved its effectiveness to correct myocardial asynchrony and improve clinical status of patients with severe congestive heart failure (CHF) and widened QRS. Despite a different

Septal flash : at the heart of cardiac dyssynchrony [PDF]

, 2020
Cardiac resynchronization therapy (CRT) has been a major step in the treatment of heart failure patients and intraventricular conduction delay. As a considerable number of patients do not respond adequately to CRT, echocardiographic dyssynchrony ...

Autophagy Activators Normalize Aberrant Tau Proteostasis and Rescue Synapses in Human Familial Alzheimer's Disease iPSC‐Derived Cortical Organoids

Advanced Science, EarlyView.
A new cerebrocortical organoid model using isogenic hiPSCs with familial Alzheimer's mutations recapitulates key AD features, including amyloid‐beta and phospho‐Tau aggregation, neuronal hyperexcitability, and synapse loss. Single‐cell RNA‐seq reveals aberrant pathways in excitatory and inhibitory neurons.

Normalization of the EKG in patients with right bundle branch block by Right ventricular pacing

Majalah Kardiologi Indonesia, 2013
Right ventricle apex (RVA) pacing bypasses the His-Purkinje system result-ing in left bundle branch block like pattern on surface EKG. In preexisting right bundle branch block (RBBB), pacing from certain location of RV might change the EKG pattern.

Electro-energetics of Biventricular, Septal and Conduction System Pacing [PDF]

, 2021
Abnormal electrical activation of the ventricles creates abnormalities in cardiac mechanics. Local contraction patterns, as reflected by strain, are not only out of phase, but also show opposing length changes in early and late activated regions ...
