Transcription of Brain Natriuretic Peptide and Atria1 Natriuretic Peptide Genes in Human Tissues. [PDF]

open access: yes, 1994
We have compared the expression of atria1 natriuretic peptide (ANP) and brain natriuretic peptide (BNP) genes in various human tissues using a quantitative polymerase chain reaction technique.

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

Twisted atrioventricular connections in double inlet right ventricle: evaluation by magnetic resonance imaging [PDF]

open access: yes, 2008
Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed

Sudden Death and Left Ventricular Involvement in Arrhythmogenic Cardiomyopathy [PDF]

open access: yes, 2019
BACKGROUND: Arrhythmogenic cardiomyopathy (ACM) is an inherited heart muscle disorder characterized by myocardial fibrofatty replacement and an increased risk of sudden cardiac death (SCD).

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.

Disorders of cardiac hemodynamic in attack period of bronchial asthma in children [PDF]

open access: yesMedičnì Perspektivi, 2016
By dopplerechocardiography method there was studied functional state of cardiac ventricles and character of hemodynamic disorders in 48 patients aged 5-17 years in attack period of moderately-severe and severe bronchial asthma.

Skeletal Muscle Ventricles for Total Heart Replacement

open access: yesAnnals of Surgery, 1990
Skeletal muscle ventricles (SMV) were constructed from canine left latissimus dorsi muscle. The animals were divided into three groups: group A (n = 5), SMVs rested 4 weeks without electrical conditioning; group B (n = 6), SMVs rested 4 weeks and then electrically conditioned for 6 weeks; group C (n = 5), SMVs rested 18 weeks without electrical ...

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.

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.
