but heart failure most commonly first begins with left ventricular /systolic failure, which leads to right ventricular failure although signs of heart failure may become more evident with right ventricular failure. Systolic failure (Pumping) Most heart failure derives from systolic failure, or the inability of the heart to
Left atrial abnormality by electrocardiogram predicts left ...
Key words: left atrial abnormality, ventricular hypertro- phy, right bundle-branch block, left atrial abnormality, left ventricular mass, age, body mass index, body surface area, frontal axis Introduction Left ventricular hypertrophy (LVH) on the electrocardio- gram (ECG) may be masked in the presence of complete right

Normal myocardial function in severe right ventricular volume overload hypertrophy. Am J Physiol Heart Circ Physiol 280: H11–H16, 2001.—Severe left ven-tricular volume overloading causes myocardial and cellular contractile dysfunction. Whether this is also true for severe right ventricular volume overloading was unknown. We

4. Right ventricular hypertrophy Pathophysiology: The figure below compares the normal anatomy and blood flow of the heart to that found in Tetralogy of Fallot. The initial defect in TOF is a narrowing of the right ventricular outflow tract into the pulmonary artery.
in right heart chamber dimensions. However, less than optimal right ventricular (RV)–arterial coupling may already cause a decreased aerobic exercise capacity by limiting maximum cardiac output. In more advanced stages, RV systolic function cannot remain matched to afterload and dilatation of the right heart chamber progressively develops.
left ventricular hypertrophy, and diabetes mellitus are the most common culprits leading to heart failure [3,4]. The transition from an index event to overt heart failure is not well understood, but the different causes of cardiac remodeling share common molecu-lar, biochemical, and mechanical pathways. Remod-
