El acueducto romano de Ebusus

Mayurqa, 2021
The Cornelia gens was a family of the Ebusitan oligarchy who performed acts of evergetism as the financing of the construction of an aqueduct. Contemporary archeology has recovered eight sites where remains of a Roman hydraulic canalization have appeared,

ECG and Pacing Criteria for Differentiating Conduction System Pacing from Myocardial Pacing

Arrhythmia & Electrophysiology Review, 2021
During His-Purkinje conduction system (HPS) pacing, it is crucial to confirm capture of the His bundle or left bundle branch versus myocardialonly capture.

Feasibility and Safety of Permanent Left Bundle Branch Pacing in Patients With Conduction Disorders Following Prosthetic Cardiac Valves

Frontiers in Cardiovascular Medicine, 2021
Background: The feasibility and safety of left bundle branch pacing (LBBP) in patients with conduction diseases following prosthetic valves (PVs) have not been well described.Methods: Permanent LBBP was attempted in patients with PVs.

The Cardiac Conduction System [PDF]

Circulation, 2011
The human heart beats 2.5 billion times during a normal lifespan, a feat accomplished by cells of the cardiac conduction system (CCS). The functional components of the CCS can be broadly divided into the impulse-generating nodes and the impulse-propagating His-Purkinje system.

Hyperchaotic behaviors, optimal control, and synchronization of a nonautonomous cardiac conduction system

, 2021
In this paper, the hyperchaos analysis, optimal control, and synchronization of a nonautonomous cardiac conduction system are investigated. We mainly analyze, control, and synchronize the associated hyperchaotic behaviors using several approaches.

Safety and feasibility of conduction system pacing in patients with congenital heart disease

Cardiovascular Electrophysiology, 2021
Conduction system pacing (CSP) has emerged as an ideal physiologic pacing strategy for patients with permanent pacing indications. We sought to evaluate the safety and feasibility of CSP in a consecutive series of unselected patients with congenital ...

Intraoperative conduction mapping in complex congenital heart surgeryCentral Message

JTCVS Techniques, 2022
Objective: Postoperative heart block is a significant problem in congenital heart surgery because of the unpredictability and variability of conduction tissue location in complex congenital heart defects.

Neonatal Deletion of Hand1 and Hand2 within Murine Cardiac Conduction System Reveals a Novel Role for HAND2 in Rhythm Homeostasis

Journal of Cardiovascular Development and Disease, 2022
The cardiac conduction system, a network of specialized cells, is required for the functioning of the heart. The basic helix loop helix factors Hand1 and Hand2 are required for cardiac morphogenesis and have been implicated in cardiac conduction system ...

Conductivity of continuum percolating systems [PDF]

Physical Review E, 2001
We study the conductivity of a class of disordered continuum systems represented by the Swiss-cheese model, where the conducting medium is the space between randomly placed spherical holes, near the percolation threshold. This model can be mapped onto a bond percolation model where the conductance $ $ of randomly occupied bonds is drawn from a ...
