INTRODUCTION Chronic stimulation of the right ventricle with pacemaker is associated with ventricular dyssynchrony and loss of contractility, even in subjects without previous dysfunction. In these patients, there is a debate of which pacing site is less associated with loss of ventricular function. OBJECTIVE To compare pacemaker-induced dyssynchrony among different pacing sites in right vent...

OBJECTIVES We investigated whether the severity of obstructive sleep apnea (OSA) predicts blood pressure or cardiac left ventricular thickness in a clinical population of OSA patients, if adjustments are made for age, gender, use of antihypertensive agents, smoking, body mass index, history of coronary artery disease, hypercholesterolemia and circulating C-peptide concentrations. DESIGN Relat...

Acute myocarditis is a rare disease with a very diverse etiology. It produces a wide spectrum of clinical manifestations and in some cases has a fulminant course. The degree of echocardiographic impairment of myocardial contractility is also highly variable, ranging from no abnormalities to a severe deterioration in systolic function. The pattern of the condition may be diffuse or focal, and it...

background: echocardiographic evaluations of the longitudinal axis of the left ventricular (lv) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (hfnef). the evaluation of the global and segmental peak systolic longitudinal strains (pslss) by two-dimensional speckle tracking echocardiography (ste) may correlate with conventional echocardiogr...

Abstract Background Early diagnosis of cardiac amyloidosis (CA) is warranted to initiate specific treatment and improve outcomes. Conventional echocardiography unable reliably differentiate CA from other causes increased left ventricular (LV) wall thickness. Purpose To demonstrate the value a multiparametric approach utilising both standard advanced echocardiographic measures distinguish pathol...

The wall thickness of the left ventricle was measured in the hearts of 16 children and 2 adults who died of congenital pulmonary valve stenosis. A right-to-left shunt through a patent foramen ovale had existed in 12 cases and was excluded in the other 6. The thickness of the left ventricular wall and the interventricular septum was increased in the majority of hearts, especially in the older pa...

BACKGROUND To use cardiovascular magnetic resonance to investigate left ventricular wall thickness and the presence of asymmetrical hypertrophy in young army recruits before and after a period of intense exercise training. METHODS AND RESULTS Using cardiovascular magnetic resonance, the left ventricular wall thickness was measured in all 17 segments and a normal range was calculated for each....

Objectives: The aim of this study was to perform saline sonovaginography (SVG) in women with suspected rectovaginal endometriosis (RVE) in order to establish the thickness of the rectovaginal septum (RVS) in this population and to predict the presence or absence of RVE. Methods: Prospective observational pilot study. Women undergoing laparoscopy for possible endometriosis on the basis of histor...

Ultrasonic backscatter of myocardial walls is directly related to the morphometrically evaluated collagen content in humans. The integrated backscatter is also increased in hypertrophic cardiomyopathy, whereas it gives normal values in the physiological hypertrophy of elite athletes. We assessed the quantitatively evaluated myocardial reflectivity in 46 mild to moderate, clinically uncomplicate...
