Ventricular divergence correlates with epicardial wavebreaks and predicts ventricular arrhythmia in isolated rabbit hearts during therapeutic hypothermia [PDF]

open access: yes, 2020
INTRODUCTION: High beat-to-beat morphological variation (divergence) on the ventricular electrogram during programmed ventricular stimulation (PVS) is associated with increased risk of ventricular fibrillation (VF), with unclear mechanisms.

Histological study on the heart ventricle of Egyptian bovines (Bos aegyptiacus) [PDF]

open access: yesOpen Veterinary Journal, 2019
Background: The heart ventricles have thicker walls than atrium as they pump blood through blood vessels into all body organs. Aim: This study aimed to describe the histological changes of the heart ventricles in Egyptian bovine (Bos aegyptiacus) with ...

21 Tesla MRI Microimaging of Rat Heart by Superparamagnetic Antimyoglobin Bound Nanoparticles [PDF]

open access: yes, 2008
Superparamagnetic iron-oxide bound antimyoglobin (SPIOM) characteristics were analyzed at different pH. After injecting SPIOM in heart, ex vivo magnetic resonance microimaging (MRM) technique was used to visualize microvasculature of rat heart including

Functional modulation of the transient outward current Ito by KCNE beta-subunits and regional distribution in human non-failing and failing hearts [PDF]

open access: yes, 2006
Objectives: The function of Kv4.3 (KCND3) channels, which underlie the transient outward current I,, in human heart, can be modulated by several accessory subunits such as KChIP2 and KCNE1-KCNE5.

Heart transplantation for patients with single ventricle physiology [PDF]

open access: yesIndian Journal of Thoracic and Cardiovascular Surgery, 2021
There is a growing population of palliated and unpalliated single ventricle physiology patients for whom heart transplantation is the only treatment option available. There is a paucity of reports of heart transplantation in this challenging and growing subset of patients from our part of the world.

Implanted electrhydraulic artificial heart

open access: yesБюллетень сибирской медицины, 2010
The problem of full-featured, high-efficiency replacement of the heart’s pumping ability with an artificial analog is urgent all over the world. The most promising model of an implanted artificial heart is now the model with the elecrohydraulic principle

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Adversarial Convolutional Networks with Weak Domain-Transfer for Multi-sequence Cardiac MR Images Segmentation [PDF]

open access: yes, 2019
Analysis and modeling of the ventricles and myocardium are important in the diagnostic and treatment of heart diseases. Manual delineation of those tissues in cardiac MR (CMR) scans is laborious and time-consuming.

Signal-Averaged Electrocardiography in Patients with Advanced Heart Failure: A Better Indicator of Left Ventricular Enlargement Compared with Conventional Electrocardiography [PDF]

open access: yesJournal of Tehran University Heart Center, 2011
Background: The signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle.
