The Interplay of Ontogeny and Phylogeny at the Transcriptome Level of the Tetrapod Heart

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The main stages of development during which species‐specific heart anatomy is determined in the ontogeny of representative tetrapods. Transcriptomic similarity is expected earlier in development before heart anatomy diverges. ABSTRACT The tetrapod heart is characterized by three chambers in amphibians and non‐avian reptiles, as opposed to four in birds,

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

open access: yes, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

MRI Assessment of Energy Loss Within the Thoracic Aorta and Its Impact on Cardiac Function in Fontan Patients After Aortic Reconstruction

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background In Fontan patients undergoing aortic reconstruction, concerns regarding the impact of aortic function on ventricular function exist. Purpose 4D Flow MRI was used to compare energy loss (EL) within the thoracic aorta in patients with and without aortic reconstruction. Study Type Retrospective case control.

Mobitz type II second-degree atrioventricular block: a commonly overdiagnosed and misinterpreted arrhythmia

open access: yesFrontiers in Cardiovascular Medicine
Mobitz type II second-degree atrioventricular block (AVB) is an electrocardiographic pattern that describes what appears to be an all-or-none conduction without visible changes in the AV conduction time or PR intervals before and after a single non ...

Single-chamber Versus Dual-chamber Implantable Cardioverter Defibrillators: Do We Need Physiologic Pacing in The Course? [PDF]

open access: yes, 2006
Background: Many patients with ICD receive different antiarrhythmic drugs (e.g. sotalol, amiodarone, β-blockers) because of ventricular or atrial tachycardias.

Protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using extracellular field potential recordings of isolated atrioventricular-node of rabbit [PDF]

open access: yes, 2011
Introduction: Recent studies have shown acute cardioprotective effects of cyclosporine. The aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using ...
