Six transition patterns and seven capture types in different left bundle branch bipolar pacing configurations

Frontiers in Cardiovascular Medicine
AimsThis study aims to explore the different transition patterns and capture types during two bipolar pacing tests based on the selective left bundle branch (LBB) capture determined by the continuous pacing and recording technique.MethodsIn total, 67 ...

Acute impact of pacing at different cardiac sites on left ventricular rotation and twist in dogs. [PDF]

PLoS ONE, 2014
We evaluated the acute impact of different cardiac pacing sites on two-dimensional speckle-tracking echocardiography (STE) derived left ventricular (LV) rotation and twist in healthy dogs.Twelve dogs were used in this study.

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Deterioration of Cardiac Function Complicated by Ventricular Tachycardia After the Implantation of an Artificial Cardiac Pacemaker and Upgrading to CRT‐D: One Case Report

Clinical Case Reports
We reported an aging male patient who experienced deterioration of cardiac function accompanied by the onset of ventricular tachycardia 10 months after right ventricular pacing (RVP).

Location! The unanswered question in right ventricular pacing [PDF]

Journal of Nuclear Cardiology, 2015
Location, like in real estate, is the most important question in electrophysiology as it determines the acute and long-term outcomes in patients undergoing ablation as well as placement of pacing or high voltage leads. Right ventricular (RV) apex is the most commonly selected location for placement of RV pacing leads. This preference reflects the ease,

SpartanAnatomy.org: Evaluating a new interactive neuroradiology tool for early medical education

Anatomical Sciences Education, EarlyView.
Abstract Teaching neuroanatomy through the lens of magnetic resonance imaging (MRI) offers medical students a strong foundation for success. However, many existing MRI learning resources lack interactivity and user‐friendliness, require payment, or include an overwhelming number of labeled structures.

Immersive virtual reality as a teaching tool in neuroanatomy: A scoping review

Anatomical Sciences Education, EarlyView.
Abstract Basic core courses in various undergraduate programs, such as neuroanatomy, pose a challenge for students due to the large volume and complexity of the content. In this context, educational technologies such as immersive virtual reality (IVR), which allow students to actively interact with learning materials, offer a complementary pedagogical ...

Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.

A dual-chamber pacing mode to minimize ventricular pacing

Zdravniški Vestnik, 2005
Background: Though patients with sick sinus syndrome theoretically need an atrial pacemaker only, they usually receive a ventricular or a dual-chamber pacemaker because of possible developement of atrioventricular conduction abnormalities.

Is Right Ventricular Outflow Tract Pacing Superior to Right Ventricular Apex Pacing in Patients with Normal Cardiac Function? [PDF]

Clinical Cardiology, 2009
AbstractBackgroundWhether right ventricular outflow tract (RVOT) pacing is superior to right ventricular apex (RVA) pacing in terms of ventricular synchrony, cardiac function, and remodeling in patients with normal cardiac function is still unknown.HypothesisRight ventricular outflow tract pacing is superior to RVA pacing in patients with normal ...
