NettetThe left ventricle is the main chamber of your heart. It is responsible for pumping oxygen-rich blood into your aorta (the largest artery in the body). If the heart has to work too hard to pump blood, the muscles in the walls of the left ventricle thicken. This thickening is called hypertrophy. Hypertrophy means growing (trophy) too much (hyper).

NettetIncreased thickness of the LV wall was not significantly associated with LV "strain" (p = 0.1). In this population, LV "strain" alone performed as well as other single or combined ECG criteria in the recognition of LVH (sensitivity 52%, specificity 95%). Nettet7. mai 2024 · 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. In response to this pressure overload, the inner walls of the heart may respond by getting thicker.

Nettet26. jul. 2024 · A notched P wave or bifid P wave indicates left atrial enlargement, nearly always the result of a narrowed mitral valve. The mitral valve lets blood flow from the left atrium into the left ventricle. If this valve is narrow – mitral stenosis – the atrium does not have time to empty before it relaxes. lego city beach houseNettetRight axis deviation. The electrical axis of the heart is the net direction in which the wave of depolarization travels. It is measured using an electrocardiogram (ECG).
