Left ventricular hypertrophy with secondary repolarization abnormalities as seen on ECG Histopathology of (a) normal myocardium and (b) myocardial hypertrophy. Scale bar indicates 50 μm. Gross pathology of left ventricular hypertrophy. Left ventricle is at right in image, serially sectioned from apex to near base.
Ventricular hypertrophy causes a dynamic pressure gradient across the left ventricular outflow tract (LVOT), which is associated with further narrowing of the outflow during systole. Pulling of the mitral valve leaflets towards the septum contributes to the outflow obstruction.
Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart. [ 1 ] [ better source needed ] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur.
Cardiomegaly is the state of an enlarged heart, and cardiac hypertrophy the thickening of the muscular wall of the heart, specifically the left ventricle, which pumps oxygenated blood to the aorta. Especially during an intensive workout, more blood and oxygen are required to the peripheral tissues of the arms and legs in highly trained athletes ...
Left axis deviation symptoms depend on the underlying cause. [5] For example, if left ventricular hypertrophy is the cause of LAD, symptoms can include shortness of breath, fatigue, chest pain (especially with exercise), palpitations, dizziness, or fainting. [6]
HFpEF is characterized by abnormal diastolic function: there is an increase in the stiffness of the left ventricle, which causes a decrease in left ventricular relaxation during diastole, with resultant increased pressure and/or impaired filling. [2] There is an increased risk for atrial fibrillation and pulmonary hypertension.
The most common causes of cardiomegaly are congenital (patients are born with the condition based on a genetic inheritance), high blood pressure (which can enlarge the left ventricle causing the heart muscle to weaken over time), and coronary artery disease. In the latter case, the disease creates blockages in the heart's blood supply, leading ...
Cor bovinum or cor bovis refers to a massive hypertrophy of the left ventricle of the heart due to volume overload, usually in earlier times in the context of tertiary syphilis but currently more often due to chronic aortic regurgitation, hypertensive and ischaemic heart disease.
