Left ventricular hypertrophy - Symptoms and causes - Mayo Clinic
2024年8月6日 · Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber, called the left ventricle. This thickening may increase pressure within the heart. The condition can make it harder for the heart to pump blood. The most common cause is …
Understanding LVH Part 1: Concentric, Eccentric and ... - Cardioserv
The main contribution of echo in the management of hypertension is the assessment of left ventricular mass (LVM). In this blog we describe left ventricular hypertrophy (LVH) and identify the different categories of concentric, eccentric and concentric remodeling.
Left Ventricular Hypertrophy - StatPearls - NCBI Bookshelf
2023年8月8日 · Eccentric left ventricular hypertrophy is induced by an increased filling pressure of the left ventricle, otherwise known as diastolic overload, which represents the underlying mechanism for volumetric or diastolic overload in patients with regurgitant valve lesions such as aortic or mitral regurgitation as well as in the case of dilated ...
Concentric or Eccentric Hypertrophy: How Clinically Relevant …
2004年2月23日 · Different combinations of volume and pressure overloads cause different left ventricular (LV) geometric adaptations. Whereas this cause-effect relationship is obvious for valve disease, because clear-cut types of overloads are easily recognizable, in systemic hypertension the type of cardiac load is less evident but at least as important for LV ...
心臟篇（1）：認識心臟肥大 - Blogger
2018年1月8日 · 基本上，左心室肥大有兩種型態：同心肥大（concentric hypertrophy）和偏心肥大（eccentric hypertrophy）。 這兩種型態的心臟肥大都有其各自生理與病理的肇因。 要了解心臟肥大的肇因，就非先了解Laplace定律的生理意義不可。 Laplace 定律. 此定律所談的是心室壁應力（ventricular wall stress，σ）。 基本上，左心室類似橢圓，但為著方便討論起見，總是將左心室看作是個圓。 根據Laplace定律所言：心室壁應力與（1）腔室內、外的壓力差（也就是透壁 …
Eccentric Versus Concentric Hypertrophy - RK.MD
2017年12月12日 · This eccentric hypertrophy creates a dilated ventricular chamber with relative wall thinning. In contrast, concentric hypertrophy is more often associated with chronic pressure overload states like hypertension or aortic stenosis.
Left Ventricular Hypertrophy - Cleveland Clinic
2021年9月20日 · Left ventricular hypertrophy (LVH) makes it harder for the heart to pump blood efficiently. It can result in a lack of oxygen to the heart muscle. It can also cause changes to the heart’s conduction system that make it beat irregularly (arrhythmia).
What is Left Ventricular Hypertrophy (LVH)? - American Heart Association
2024年5月30日 · Left ventricular hypertrophy, or LVH, is a term for a heart’s left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle.
Left ventricular hypertrophy | Radiology Reference Article ...
2024年8月22日 · Left ventricular hypertrophy (LVH) is present when the left ventricular mass is increased. It is a common condition, typically due to systemic hypertension, and it increases with age, obesity and severity of hypertension. Studies have demonstrated a prevalence on echocardiography of 36-41% in hypertensive patients 1.
Left Ventricular Hypertrophy | Circulation - AHA/ASA Journals
2000年7月25日 · This review will focus on the pathogenesis of pressure- versus volume-overload types of left ventricular hypertrophy (LVH), detection, clinical manifestations, and prognosis. Where possible, observations from human studies will be presented that have led to major insights regarding the pathogenesis of hypertrophy and the potential for its reversal.
